What make are they? The 18th edition regs say that you can only fit breakers that match the manufacturer of the board. All boards are slightly different and gone are the days we use to mix and match. Don’t get me wrong it’s a fantastic idea and glad they are finally here but need to make sure we still conform to current regs!!!

I need circuit diagram for water level indication through GSM sim card

it is too much educating site and am too happy with this one dear developers.

It’s good in these modern technology. But there is a control switch in between circuit breaker & Appliance,so how could be operate it, it’s more good if same technology could be use between appliance and switch.

Can this, or another product, be used for the mains breaker (breaker for incoming mains as opposed to individual house ciruits)? I have a need to be able to remotely control (wifi or ethernet is fine) the main breaker in the house.

Yes You can if used according to the total load rating factors.

I’m impressed with the skills I have received from this field. I’m looking forward to do more projects with you.

Hi, I can’t find any information how to reset this breaker to factory default settings. I would like change the WiFi router as the old one has to short range and device loosing connection.

Pls suggest something for industrial purpose wifi smart devices

Not impressed being a ret master electrician 20 years in the field, A breaker is designed to trip when encountering a overload . short, etc and to find the problem first , and than manually re setting the breaker with your finger, This thing will wind up burning alot of house’s and buildings down . I would never use one ret or not just asking for trouble !

Thank you for informing us about the new technology MCBs….

The Best Smart Plugs

A collection of plug-in smart outlets that we tested to find the best ones.

Using a smart plug is the cheapest, easiest way to remotely control any electrical device in your home. Just plug one into an electrical outlet, and add a lamp, fan, or other on/off device. Then set it up with an app, and—boom—you’re making magic.

We recommend the TP-Link Kasa Smart Wi-Fi Plug Slim (EP25) for inside the home and the TP-Link Kasa Smart Wi-Fi Outdoor Plug (EP40A)  for outdoor use, since they both work really well on their own and when paired with many other devices.

We also recommend the TP-Link Kasa Smart Wi-Fi Power Strip (HS300) if you want to be able to plug in and independently control and automate multiple devices.

Everything we recommend

TP-Link Kasa Smart Wi-Fi Plug Slim (EP25)

The best smart plug.

This smart plug worked reliably in tests, and it includes real-time energy monitoring and an Away Mode. Also, it’s widely compatible with all the major smart-home platforms.

Buying Options

This model turns one outlet into six independently controlled smart ones, with built-in energy monitoring and integration with Amazon Alexa and Google Home (but not Apple Home). It also has three USB ports.

wifi trip switch

TP-Link Kasa Smart Wi-Fi Plug Mini (EP10)

The best smart plug for tight spaces.

This smart plug is easy to use, affordable, and small enough to fit behind furniture. It can also track the amount of time (in hours and minutes) you’re using electrical devices.

Things to know

Many smart plugs can monitor usage in hours and minutes, and some can track actual energy usage in kilowatt-hours.

Most smart plugs are rated for 15 amps of current and so should be used only with low-power devices like lamps and small appliances.

Indoor smart plugs are compact but not weather-resistant. Outdoor models are bulkier but ruggedized.

Consider where a plug will be placed—for tight spots, like behind furniture, you may have to use a mini model.

Compatible with: Amazon Alexa, Apple Home, Google Home, Samsung SmartThings

The Kasa Smart Wi-Fi Plug Slim (EP25) includes all of the features you’d want in a single-outlet smart plug. In addition to remote-control access, a timer, and the ability to be scheduled, it can be integrated with a large number of other smart-home devices through Alexa, Home, and Google Home. It also supports real-time energy monitoring, so you can keep tabs on electricity use in hours and minutes, or in watts and kilowatt-hours. It’s available only in a two-pack and a four-pack , but the price is similar to or less per unit than that of other plugs we like.

The Kasa Smart Wi-Fi Outdoor Plug (EP40A) is built to weather the outdoors. (You should never attempt to use an indoor smart plug outdoors.) The EP40A has an operating-temperature range of -4 to 122 degrees Fahrenheit, so it can handle a wide range of weather. It includes two outlets that you can control independently using the app or voice (via Alexa, Google Home, or Siri—and if you don’t need Siri, you can go with the Kasa EP40 ), and it’s easy to set up and use. This smart plug can also track the running time of devices plugged into it, in hours and minutes.

Compatible with: Amazon Alexa, Google Home, Samsung SmartThings

The Kasa Smart Wi-Fi Power Strip (HS300) transforms one wall plug into six independently controllable outlets, so you can turn different devices on and off, and you can also create separate schedules and triggers. Of the smart power strips we tested, this one is the most well built. It also has the most USB charging ports (three) for smartphones and tablets, as well as the longest power cord. And it supports energy monitoring (in watts and kWh) and voice control via Amazon Alexa and Google Home.

The Kasa Smart Wi-Fi Plug Mini (EP10) is the smallest and least expensive of our picks, but it lacks energy monitoring or Home support, which our top pick has. Sold in packs of two or four, this smart plug has built-in usage monitoring. So it can keep tabs on the precise amount of time you’re using a device (like a fan or AC) that’s plugged into it (though it doesn’t provide info on the actual energy consumption).

The research

Why you should trust us, who this is for, how we picked and tested, our pick: tp-link kasa smart wi-fi plug slim (ep25), our pick: tp-link kasa smart wi-fi outdoor plug (ep40a), power-strip pick: tp-link kasa smart wi-fi power strip (hs300), runner-up: tp-link kasa smart wi-fi plug mini (ep10), other good smart plugs, the competition, what to look forward to.

I first started testing smart-home devices more than 20 years ago, back when the only smart-home devices were X10 . Since 2016, I’ve been covering smart-home gear for Wirecutter, and I’ve had my hands on everything from in-wall light switches , smart bulbs , and water-leak sensors to smart video doorbells , indoor security cameras , and security systems . I’ve also written tech articles for The New York Times, Wired, and Men’s Health, among others.

Bringing smart functionality to your home doesn’t have to be complicated or expensive. If you have a smartphone and an empty outlet, you can use a smart plug to control, schedule, and automate nearly any electrical device. You don’t need programming skills or an installer on speed dial to set up smart outlets, and they become immediately useful with very little fuss.

For example, hooking even just one smart plug to your old table lamp ensures that you’ll never have to enter a dark house. And if you have mobility or dexterity issues, a smart plug can make it much easier to set lights, fans, speakers, air purifiers, game consoles, and air conditioners on a schedule, or to control them with a smart speaker and the sound of your voice.

Our four top picks for the best plug-in smart outlets, in several different styles.

We’ve been covering smart plugs for over seven years now. All of the models we’ve tested share a few common features that we think are essential for anyone:

  • They allow you to create a schedule that turns electrical devices on and off at specific times of the day or week. That’s very convenient, and it can also be a crucial aid for anyone who has mobility issues and difficulty reaching light switches or other controls.
  • They can be integrated with popular smart-home services through support for Amazon Alexa, Apple Home, and Google Home. Some devices also support Matter, so all of the smart-home platforms work together. All of this integration allows you to control the devices with the sound of your voice, or you can combine them with other smart devices—such as a motion sensor that triggers a device on or off when someone comes into a room.
  • They have physical buttons you can use to turn outlets on or off.

Additionally, some smart plugs can monitor how much you’re using a device that’s plugged into it (reported in hours and minutes), while others actually track the amount of energy consumed (in kilowatt-hours). Either of these can help you determine what it costs to run a power-hungry device, such as a TV or an air conditioner. Though we don’t think either is a must-have feature, for some it may be a nice perk.

For this guide we considered both indoor and outdoor smart plugs, with single and multiple outlets. To test smart-plug candidates, we use them with fans, table lamps, a noise machine, a radio, and Christmas lights. We used an iPhone 12, a Google Pixel 7 Pro, and an iPad to review the plugs’ companion apps. And we used several Echo speakers, a Google Mini, and an Apple TV to see how each smart plug reacted to voice commands and smart-home integration.

Two of the best plug-in smart outlets that we tested, both TP-link Kasa models.

Once we narrowed our pick candidates, we reviewed their respective privacy policies, to make sure they were in line with those of other smart-home companies. We then sent a security and privacy questionnaire to each of the manufacturers, asking more-specific questions about each one’s security policies and practices and how they handle device owners’ data. Among other things, that includes login practices, whether a company supports two-factor authentication, what user data is encrypted, and what data is recorded and shared. We also connected those devices to Firewalla Purple SE , a firewall device that monitors the communications of all devices on a network and reports which devices are sending out data and to what country.

The small, white, rectangular TP-Link Kasa Smart Wi-Fi Plug Slim (EP25), our pick for the best plug-in smart outlet.

The TP-Link Kasa Smart Wi-Fi Plug Slim (EP25) combines all of the best features you can find in a smart plug at a price that makes it possible to deploy them throughout your home. This smart plug provides reliable remote control and scheduling, and it works with all of the major smart-home platforms. It also includes energy monitoring, so you can track precisely how long you use a device as well as how much power it consumes.

It’s smart but still simple. Setting up the EP25 is quick and easy. In our testing, it promptly responded to both app and voice commands. We also found it was straightforward to create Schedules based on specific times as well as on our local sunrise/sunset, and we used them to control fans and lights.

Choose your own app. The EP25 works with the Kasa app but also the newly released Tapo app , which is the better option. Both were extremely easy to use, but the Tapo app allows you to access, group, and control both Kasa and Tapo devices which is more streamlined. For instance, we created a group with the EP25 and the TP-Link Kasa Smart Wi-Fi Light Switch Dimmer KS220 (our in-wall dimmer pick). And we were able to turn the dimmer in our entryway and a living room lamp on and off with a single click (instead of having to individually trigger each device).

It’s widely compatible. The EP25 can be set up using an iOS or Android app, or using Apple’s Home app, and it’s compatible with all of the major smart-home platforms. But if you’re using Apple’s Home app, the setup is slightly different. For instance, you can bypass using TP-Link’s app, but then you miss out on a few attractive features—most notably the EP25’s built-in energy monitoring and the ability to use the Away Mode (which triggers devices randomly so it looks like someone is home).

It can save energy (and money). Energy monitoring makes the EP25 a standout. It allows you to track device usage in hours and minutes for the day, and it can also provide that information for the past seven and 30 days. It also delivers stats for the day in watts and kilowatt-hours (kWh), as well as the Daily Average and Total Consumption numbers for the past seven and 30 days. Those allow you to keep tabs on which devices you might be running too much—and which ones are driving up your energy bill.

Flaws but not dealbreakers

  • The EP25 is sold only in packs of two or four . Though the price per smart plug is good, you may not want to pay for multiple plugs—especially if you need only one. Instead, you can opt for the TP-Link Tapo P125 , which is sold individually and has Matter support, but doesn’t include energy monitoring, though it does cost more per plug.

The black, weather-resistant, TP-Link Kasa Smart Wi-Fi Outdoor Plug (EP40), our pick for the best plug-in smart outlet.

If you’re looking to extend your smart home outdoors, the TP-Link Kasa Smart Wi-Fi Outdoor Plug (EP40A) is easy to set up and use, reliable, and affordable, and it includes two outlets you can control independently. It’s also widely compatible with several major smart-home control apps, but if Apple Home and Siri aren’t a necessity, you can go with the cheaper Kasa EP40 , our previous outdoor plug pick.

It’s pretty rugged. The EP40A can withstand temperatures between -4 to 122 degrees Fahrenheit, which is pretty typical for outdoor plugs (temperatures below or above those numbers may not even be an issue—the EP40A is just not guaranteed to work in those conditions). Like most outdoor smart plugs, this model has an IP64 rating, so it’s weather-resistant but not considered weatherproof. That means it can’t tolerate being submerged in water, but it can withstand dust and water splashes (which would include flurries and snow). As you should with any outdoor plug, always plug the EP40A into an outdoor receptacle with a weatherproof box.

It’s uncomplicated. There are two buttons on the top of the EP40A that allow you to manually control each outlet. It works with both the Kasa and the Tapo iOS and Android apps, which allow you to name and control each outlet independently so that you know, for example, which one is the strand of twinkle lights and which is the pool pump. (Labeling outlets this way also makes things work more reliably when you use voice commands to smart speakers.) You can also group the outlets (perhaps in an “Outside” group), so you can turn off both outlets with a voice command or the tap of a button on your phone. All of our picks work with both the Kasa and the Tapo app, which also means this device includes an Away Mode and scheduling for individual devices.

It tracks device usage. Unlike our top pick, the EP40A doesn’t track energy usage and instead tracks how long a device is used in hours and minutes on a daily, weekly, and monthly basis.

The Kasa Smart Wi-Fi Power Strip (HS300), our pick for the best power-strip style plug-in smart outlet.

Sometimes you want more than one thing to be automated. The TP-Link Kasa Smart Wi-Fi Power Strip (HS300) stretches smart-home capabilities, with six independently controllable outlets and three USB ports. It’s an excellent option not just for home-office and entertainment uses, but also for anyone who wants to control multiple devices due to mobility and dexterity issues. For instance, you can plug in a table lamp, a space heater, a radio, and other necessities, and make them controllable via voice commands. Or you can set them on a schedule so they go on and off at the same time every day.

It converts one outlet into six smart ones. This device works with TP-Link’s two apps: Kasa and Tapo. We prefer the latter, since it allows you to group Kasa and Tapo devices together. Both apps lay out each outlet as if it were a separate device. You can rename each plug, too, so you don’t have to remember what’s plugged in where. Individually naming each plug also makes it easier to use voice commands, so you can use natural language commands like “Alexa, turn off the table lamp,” rather than “outlet 6” or something similar. You can also group all of the outlets to turn several devices on and off simultaneously. Each of those outlets also has an energy-usage feature, so you can peek at real-time power consumption based on readings from the embedded power-meter chipset, as well as daily, weekly, and monthly averages in kilowatt-hours.

It has a bonus charging area. The HS300 includes three USB ports. Although these aren’t remote-controllable, it’s handy to have another spot to power up phones, tablets, and other electronic devices.

It’s foolproof. The HS300 is the only smart power strip we reviewed that includes manual controls on the actual device for each of its outlets. And since it has the longest cord (38 inches) of any of the power-strip models we tested, you can tuck the HS300 in a corner, out of sight.

It’s not surge protection. Per TP-Link, this model is rated to reduce power spikes to 500 volts when exposed to a 6,000-volt surge in testing. That means it will clamp down high-voltage surges to that level and limit the damage to any connected devices. By contrast, for our surge-protector guide , the models we test are generally rated to lower surges—to 400 volts or lower—in the same situation. And in our own tests using 5,000-volt surges, our top surge-protector picks were able to reduce that even further, to under 200 volts. As such, we don’t think anyone should buy this Kasa power strip for its surge protection as much as for its smart-home capabilities.

How the Kasa HS300 has held up

About three years ago, senior editor Christine Ryan installed the HS300 to replace a few Wemo plugs that were controlling lamps and an espresso machine. She’s been pleased but recently had difficulty reconnecting the HS300 after changing her home Wi-Fi password. “I’ve looked all through the Kasa app, and there’s no place that I can find to update the password,” Christine said.

Unlike many smart-home device makers, Kasa doesn’t provide a way in the app to update a password after a device has been set up. Instead you’ll need to do a complete factory reset of the device and then reinstall it again from scratch; this isn’t ideal but it’s also not terribly complicated. Kasa provides full instructions here .

The small, white, rectangular TP-Link Kasa Smart Wi-Fi Plug Mini (EP10), our runner up pick for the best plug-in smart outlet.

The TP-Link Kasa Smart Wi-Fi Plug Mini (EP10) is the smallest of our picks, so it fits a little better in tight spaces you can’t or don’t want to reach that often, such as behind furniture. Otherwise, it’s almost identical to our top pick , but this one doesn’t have as many features.

It’s cheap and compact. At 2.36 by 1.5 by 1.21 inches, the EP10 is easy to place anywhere. And because it’s the least expensive of our picks, you can install these in multiple places around the house. The EP10 is sold in packs of two or four , but not individually.

It works with some smart-home platforms. Although this is not the most widely compatible plug we tested, the EP10 can be paired with Alexa and Google Home. Those integrations enable voice commands using a smart speaker or smartphone, so you can turn the plug on and off hands-free. We named the plug “Office Fan” in the app and connected it to both Alexa and Google Home. So we were able to say, “Alexa, turn the Office Fan off,” and it worked seamlessly.

It tracks usage. Like our outdoor pick , the EP10 can track device usage by day, week, and month. (In our testing, we learned that we used a lamp for roughly 16 hours a week.)

We tested a number of smart plugs that we didn’t prefer as overall picks but that are perfectly fine choices.

If Matter matters: We thought the Meross MSS115 Matter Smart Wi-Fi Plug Mini , the TP-Link Kasa KP125M Smart Wi-Fi Plug Slim , and the TP-Link Tapo P125M Mini Smart Wi-Fi Plug all worked fine, but are more expensive than our top pick—and we actually found the non-Matter Kasa model to be easier to set up with all three smart-home platforms. Plus, out of these three Matter models, only the Kasa 125M adds in energy monitoring.

If you want one plug: Our top single-outlet picks are sold in multipacks, but the Meross MSS110 is a good smart plug with support for Alexa, Home, Google Home, IFTTT, and SmartThings. We found our top pick to be a little easier to use, and the Meross is also a bit bigger (measuring 2.65 by 1.5 by 1.5 inches) than some of the other plugs we tested. If you don’t care about Home, the Roku Indoor Smart Plug SE is a good, less expensive option.

If you’re prone to torrential downpours: The Lutron Caséta Outdoor Smart Plug is IP65-rated, so it can handle water at a slightly higher pressure than the other smart plugs we tested. However, we found this single-outlet model (which also requires the Lutron Smart Bridge for remote operation) to be lacking some of the special features that our lower-cost picks offer.

If you’re interested in Thread wireless: The latest incarnation of the Eve Energy includes Thread , the low-power wireless mesh networking protocol that should allow more reliable and faster connectivity among compatible devices. It also supports Matter , but it wasn’t easy to set up with every smart-home platform and Matter doesn’t support a few key features (such as energy monitoring). Also, a single plug costs as much as a four-pack of our top pick.

If you’re all in with Alexa or Ring: We found that the Amazon Smart Plug and the Ring Outdoor Smart Plug worked fine. But prices and functionality would limit them to users who are all in with their respective ecosystems.

If you need an outdoor dimmer: The Meross MPD100 Plug-in Dimmer Outdoor Plug has a single outlet that can dim outdoor lighting. However, it has just one controllable outlet and a limited operating temperature of 14 to 104 degrees Fahrenheit.

Our top picks offer a better overall user experience and have better features than the Geeni Smart Dot , the Geeni Surge , the RCA Smart Outdoor Plug , the Monoprice Stitch Mini , the WiZ Smart Plug , the Shelly Plus Plug US , the UltraPro Plug-In 1-Outlet Wi-Fi Smart Switch , TopGreener’s TGWF115APM , TopGreener’s TGWF115PQM , Wemo Smart Plug , and GE's Cync Outdoor . However, these models performed fine in our testing.

The ConnectSense Smart Outlet2 has a double outlet, but it’s more bulky and not as user-friendly as our top picks. Also, we found the Leviton D215P-2RW Decora Smart Wi-Fi Mini Plug-In Switch , the Leviton D23LP-2RW Decora Smart Wi-Fi Mini Plug-In Dimmer , the Lutron Caséta Smart Lamp Dimmer , and the Satechi Dual Smart Outlet to be too expensive for the features each one offered.

The Ezlo PlugHub has an internal Z-Wave hub built in; this makes it chunky and may explain why it’s currently $60. That would be fine, if it weren’t so difficult to use.

We prefer our other outdoor plug picks to the Geeni Outdoor Smart Plug , the Geeni Outdoor Duo , and the Meross MSS630 Smart Wi-Fi Indoor/Outdoor Plug , since their operating temperature range is better. Also, in our testing, these three models had other performance issues.

During our testing, the Array by Hampton Single Outlet Smart Plug failed often. And we originally dismissed the Monoprice Stitch Wireless Smart Power Strip due to its lack of features and an especially short cord (19 inches). Also, it died after a year of use.

We also had setup and performance problems with the GE Enbrighten Wi-Fi Outdoor Smart Plug , the  EZVIZ 30-10B-US .

We plan to test the Aqara Border Router Plug and the Shelly Qubino Wave Plug US when they are released in the coming months. Both include energy monitoring features, but the Aqara supports dual-band Wi-Fi and also has the ability to act as a Thread border router. The Shelly is a Z-Wave plug, and so requires a compatible hub to function.

We’re also looking at the TP-Link Tapo TP25 Outdoor Plug and the Tapo P110 . The TP25 has an IP65 weatherproof rating, Matter support, and dual antennas for a greater Wi-Fi range. The P110 is an indoor plug that has many of the same features as our top pick , but it’s smaller and includes energy use monitoring.

We've started testing the Leviton Decora Smart Wi-Fi Outdoor Plug , a single-outlet model with Matter support. It claims to have better weather resistance than our current pick (-20 to 122 degrees Fahrenheit) and can be paired with the Anywhere Switch Companions (DAWSC) , a wire-free wall-mounted controller.

We also plan to test the $18 Monoprice Stitch Smart Outdoor Plug . It has an IP65 water-resistance rating, two individually controlled outlets, and works with both Alexa and Google Home.

Like traditional light switches, most smart light switches have a physical toggle, paddle, or button to turn your fixtures on, off, or dimmed. With the integration of Wi-Fi, Bluetooth, ZigBee, Z-Wave, or a proprietary connection for home automation systems, smart switches can be controlled from your smartphone and/or voice assistants like Alexa, Google Home, or Apple HomeKit.

Smart switches allow for features like timers and schedules, so you can turn lights (or appliances) on or off from outside the home, adding extra home security. Here are the overall benefits:

✔️ Convenience . Having the ability to switch the lights on or off remotely or with voice control is the number one benefit for most. When you're tucked under the covers and need to turn lights off, you'll understand why.

✔️ Security . Use scheduled timers to enhance home security by controlling when the lights turn on or off when you’re away from home. Timers can be set for specific times or at random.

✔️ Energy savings. Dimming capabilities and occupancy sensing can significantly cut down your electricity bill. It's also worth noting that smart switches are a cheaper alternative to smart bulbs in a whole-house setup.

✔️ Greater control. You can create a truly personalized experience using intuitive controls that work seamlessly with your existing home Wi-Fi network. A smart switch can turn on your outside lights when you're minutes from home, or set your living room blinds to roll down at dusk.

See below for the best smart light switches hand-picked by the pros at the Good Housekeeping Institute:

This Wi-Fi-connected smart switch works as a dimmer and motion-sensor all-in-one and is packed with features to enhance your standard light bulb's functionality. Our engineering pros loved that the switch includes a motion sensor to trigger the light automatically (you have the option to turn it off so it doesn't turn on at night, and it has an ambient sensor to stay off in daylight). This switch works with all kinds of bulbs, and if you happen to own other C by GE smart bulbs, the switch can also control them even if they aren't wired to the dimmer.

We found using voice-control with Alexa, Google Assistant, or Apple HomeKit compatible devices simple, as was the the accompanying iOS app. No hub is needed, but installation does require a neutral wire. (There is a 3-wire version available.) Some reviewers claim that the Android version of the app needs some work and that setting up automation for a room is a bit confusing at first.

Turn your home into a smart home for under $20 with this WiFi-connected smart switch and dimmer. With n o hub required, this switch is easy to install as it only requires a neutral wire (no 3-way). It includes three buttons (for dimming, on, and off) plus a status light. Designed to support Amazon Alexa, Google Assistant, Microsoft Cortana, and IFTTT for voice control, or you can also control your electronics from anywhere using the Kasa IOS and Android app.

In our testing, we found the app to be very user-friendly, particularly for automated scheduling and dimmer controls. You can even set the controls based on how you touch it (a long press or a double tap, for example, can instantly turn it on/off or fade.)

Our engineering team noted they loved this switch so much because it works with so many smart home devices like motorized smart shades, ceiling fans, thermostats, and speakers. In addition to connecting over its own proprietary protocol using a not-included smart bridge (hub), this dimmer/switch supports 3-way wires, doesn't require a neutral wire for installation and has an easy-to-use, multi-button keypad.

But the top cool-factor is all of the features, including scheduling, scenes, zones, and geofencing (which means your lights will automatically turn on or off when you leave or arrive at home.) Although it's a bit more expensive than some other picks, the Lutron Caséta dimmer switch works with Amazon Alexa, Apple HomeKit, and Google Assistant, as well as SmartThings, Sonos, and many other popular smart-home systems for ultimate control.

If you want an easy-to-use, smart light switch that is packed with features and connects directly to your home WiFi network (no hub needed), then the Legrand Tru-Universal Dimmer is the one for you. Not only does this claim to control every standard bulb, but they say it auto-detects and calibrates with LED, CFL, halogen, incandescent, and EFL bulbs.

It is also compatible with Apple Homekit, Amazon Alexa, and Google Home, so you can use voice control with your favorite assistant. Simply install your smart dimmer using a neutral wire, download the IOS app on your iPhone (sorry, Androids), connect to WiFI, and start scheduling, dimming, and setting the scene.

If you're already a fan of Philips Smart devices, you will want this dimming switch for even more convenience and features. It can be used as a wireless remote or a mounted wall switch that doesn't require any electrical installation, other than peeling the covering off the adhesive back. Although it only controls Hue bulbs and devices, having the power to set the scene and dim without having your phone nearby is magical. The Hue Bridge is required, but if you already have Hue bulbs, you have that set.

This dimmer/switch can be controlled by your voice through Amazon Alexa, Google Home, and Apple HomeKit. It's also compatible with a host of other smart home platforms. The GH Institute experts love that the intuitive app for IOS and Android is full of fun controls and creative themes for your Hue bulbs. You can set schedules, timers, and custom scenes in seconds via your smartphone, voice, or with the handy remote that comes with the dimmer switch. When using your switch, use the on button to switch between four light recipes without the Philips Hue app for even more convenience.

Designed with Z-Wave technology for increased communication range and no WiFi needed, this smart dimmer switch features two-way feedback, is scene capable, and is supported by security systems, hubs, and gateways that are Z-Wave enabled. The rocker style is simple and clean, allowing users to push the top of the paddle to turn on or the bottom to turn off. Wall plates come in six colors to suit your decor.

You do need a separate Z-Wave enabled hub, such as Wink or SmartThings , to schedule lights to dim or turn on/off automatically and control via app, or you can use voice control using Amazon Alexa. We found that installation was pretty easy; you just need a neutral wire.

Not only does the WeMo Dimmer look cool with its glowing LED status light, but one of the best features of the switch is that it calibrates to work with any light bulb for maximum dimming with minimum flickering. Online reviewers love that it also has a night mode button that keeps you from blinding yourself with full-on bright lights if it's the middle of the night. They did comment that it is virtually impossible to remember the seven different statuses, though.

Since this dimmer switch connects to your WiFi network, you don't need a hub, but you will need a neutral wire. The WeMo app supports numerous smart products and offers many features, including light scheduling and various lighting modes. You'll also be able to review power-consumption data and control multiple WeMo devices with a single swipe. Although it's not compatible with a ton of smart home systems, it does work with Alexa, Apple HomeKit, and Google Home, for hands-free voice control.

What are the best smart light switches?

line, rectangle,

Before you settle on any particular smart switch, there are several things you should think about beforehand. Here's a quick rundown of things to consider:

Smart home compatibility: Looking to integrate with smart home platforms like Google Home, Amazon Alexa, or Apple HomeKit? You might want to check that your switches are compatible before you buy them. You also want to check that your switches are compatible with your existing smart devices or ones you plan to buy in the future (i.e. thermostat or fans.)

Connectivity: The way the smart switches "talk" to your app varies. Some are controlled via a wireless technology called Zigbee or Z-wave, others over your Wi-Fi network or Bluetooth.

  • Wi-Fi connectivity means that you can control your switches anywhere you have an internet connection.
  • Bluetooth switches can only connect to a phone within a specific range.
  • ZigBee and Z-Wave use wireless communication to send data back and forth to each other and to your phone. Hub-based switches like those using ZigBee and Z-Wave can work independently or collectively and can be controlled by multiple users. While ZigBee and Z-Wave aren't directly compatible with one another, smart speakers like Alexa and Google Home now support one or more, helping to bridge the gap.

Setup: You will want to research how easy it is to set up the switches – in our testing, some required connection to a hub or gateway, others require more robust electrical work. You'll also want to take into account how the accompanying app works, and how fast the switch responds to voice commands.

Hard-wiring: Most smart switches require a neutral wire (single-pole) to operate; some just stick on the wall; some require three-way wiring (three-pole). Although single-pole and three-way switches look almost the same when installed, there is one big difference: A single pole switch has "on" and "off" markings and one neutral wire, a three-way switch doesn't. That's because the three-way switch is used in conjunction with another three-way switch to power a single light fixture, and turning the light fixture on and off may require different lever positions.

Dimmers: Even though most modern CFL & LED bulbs are dimmable by design, make sure to check compatibility with the types of bulb you intend to control.

App features: Some lighting apps offer only basic on/off and scheduling options, while others include special effects or third-party integrations that increase the lights' functionality.

The 5 Best Smart Switches of 2024

Take high-tech control of your home's lighting

wifi trip switch

The Spruce / Amelia Manley

One of the most seamless ways to integrate smart home technology throughout your house and daily life is by upgrading the light switches on your walls to internet-connected smart switches and dimmers. Using your Wi-Fi network or other wireless connectivity, these modern switches give you remote control through a mobile app or voice assistant, often serving as an alternative to installing individual smart light bulbs.

"Automating with the use of light switches is an effective and often less expensive way to automate your lighting system," says Johann Whitehouse, owner of the home automation company WH SmartHome . "In addition to the cost benefits, replacing switches allows you to change out the bulbs whenever needed without worrying about losing your automation. If the light bulb went out or you decided you wanted a different color temperature on those bulbs, everything will continue to work exactly the same."

With Whitehouse's expert insights as a foundation, we researched a wide range of smart switches from various leading brands, including units with dimmers, three-way switch support, and motion sensors. We considered the products' connectivity options , feature sets , and, their compatibility with popular smart platforms.

A smart switch is an energy-efficient, electrical switch that can be controlled via smartphone app, voice assistant, or other smart home device. Smart switches are conveniently installed to replace traditional light switches, but they can also be used to control fans and appliances, too.

What to Know Before You Get Started

There are a number of terms you may come across when looking into smart switches, here's what you need to know:

  • Three-way switches typically come in pairs and can control the same light fixture from two different places in a room, such as the top and bottom of a staircase or either end of a hallway. 
  • Smart switches often require neutral wiring to deliver constant power to the switch. From homes without a neutral wire (often built before the 1980s), no-neutral smart switches are the ideal option. "There's not a definitive benefit for the function of the switch to not need a neutral wire, but it definitely helps with ease of wiring," says master electrician Ryan DalPezzo of RD Matthews Electrical Contracting . "It's easier for the installation since no additional wiring would have to be added." 
  • Most smart switches connect directly to your Wi-Fi network, but certain models can utilize Z-wave wireless technology to interact with other smart devices in your home, provided you already use a Z-wave network. "The biggest advantage Z-wave has is the ability to use very little power and effectively build a mesh, expanding the coverage area in which the switches can communicate," says Whitehouse. "The biggest disadvantage is the need for a dedicated hub for this to work, translating the signals between Wi-Fi and Z-wave." 
  • Smart switches are generally used to replace a single-pole switch , which is the most common type of wall switch found in homes, controlling a single 120-volt circuit. (Double-pole switches for 240-volt circuits are much less common and used for larger appliances or industrial settings.) 
  • Most smart switches connect to your home Wi-Fi network as their connectivity method to access the internet and remote features. Some may require a separate hub or bridge to facilitate local wireless communication, whether it's a network for Z-wave, Matter, or a brand-specific platform. 
  • Smart switch styles can range from a single button—often appearing similar to a modern paddle switch —or a rocker switch with two positions, to more complex configurations with dimming buttons. (Smart switches are not usually made in the traditional toggle switch style.)

Best Overall

Kasa smart wi-fi dimmer switch ks225.

Great compatibility through Matter

Simple Bluetooth-assisted setup

Gentle fade features

Supports Amazon Alexa and Google Home

Neutral wire required

No three-way support

Hub device required for Matter

Within its Kasa Smart brand, TP-Link produces several high-quality smart switches to suit a variety of situations, and the KS225 Wi-Fi Dimmer Switch spotlights the latest technologies. Installing the single-pole switch does require a neutral wire, but as long as you have one at the location, the process is relatively straightforward. The primary on/off switch is a large button that looks like a typical paddle-style switch, but you can't push both the top and bottom of it like a true rocker. Two smaller buttons increase or decrease your lights' brightness (with a KS205 model available without dimming). 

Connecting the switch to Wi-Fi and the Kasa Smart app is also simple, thanks to a setup process aided by Bluetooth wireless. Through the app, you'll be able to control the switch from anywhere with internet access, including full brightness control, scheduling, multi-device scenes, and an away mode to make it look like you're home. Its option to gradually fade lights on or off is another nice touch. 

The KS225 supports Amazon Alexa and Google Home and can take advantage of voice commands and integrations with those ecosystems, but it especially stands out as one of the few switches at the time of writing to support Matter. Designed to foster universal compatibility across brands, the Matter standard allows Matter-compatible devices from any smart platform (including Apple Home and Samsung SmartThings) to work smoothly together, as long as you have a device that can serve as a Matter hub for the network. 

Connectivity: 2.4GHz Wi-Fi, Matter hub | Switch Style: Single-button paddle with dimmer | Circuit Type: Single-pole | Control Method: Kasa Smart, Amazon Alexa, Google Assistant, Matter

Wyze Switch

Good compatibility and integrations

Multi-press functions

Available in packs of 3

Wyze has quickly made a name for itself as a budget-friendly smart home brand, and the one-button Wyze Switch is a great example of its simple but effective offerings. While you can find switches with more advanced features like dimming and motion sensing that are fairly close in price, each dollar can make a difference if you're buying multiple switches to place throughout your home. The Wyze Switch also comes in packs of three for a better value (but note that three-way switches are not available). 

The Wyze app gives you the basic controls to turn the switch on and off, set schedules and timers, and activate vacation mode. You unlock the potential for much more advanced functions and automation, though, by integrating the switch with other Wyze gadgets—particularly smart bulbs that would essentially become useless if turned off by a traditional switch. You can even program different customized actions to different types of button presses, like turning on all your Wyze Bulbs with a triple-press or opening smart locks with a long-press. The Wyze Switch is also compatible with Alexa and Google Home, and you can set up other third-party automations through IFTTT applets. 

Connectivity: 2.4GHz Wi-Fi | Switch Style: Single button | Circuit Type: Single-pole | Control Method: Wyze, Amazon Alexa, Google Assistant, IFTTT

Best Dimmer

Leviton decora smart dimmer switch, wi-fi 2nd gen d26hd.

True rocker switch and dimmer

Great compatibility, including Matter

Wireless multi-location option

Leviton's Decora switches were so iconic that they became the household name for the switch style, so it's no surprise that today's D26HD Smart Dimmer Switch is a dependable, top-quality option. Its physical design may look and feel more familiar to more users, with the ability to push both the top and bottom and half of the switch rather than just a single button. The dimmer controls are also a simple rocker alongside the main switch. While the D26HD installs at a single-pole location with a neutral wire required, you can wirelessly pair it with Leviton's Anywhere Companion switches or dimmers for control at two or more locations on your wall. 

This second-generation model already worked with the major smart platforms and voice assistants from Amazon, Google, and Apple, but a firmware update further adds support for the universal Matter standard. It's a forward-thinking step that lets you integrate the switch with any Matter-compatible platforms or devices if you have a Matter network set up. The My Leviton app also gives you a rich suite of remote settings and controls, including preset brightness levels and fade rates, multi-device grouping, and schedules based on sunrise/sunset times. 

Connectivity: 2.4GHz Wi-Fi, Matter hub | Switch Style: Rocker switch with rocker dimmer | Circuit Type: Single-pole | Control Method: My Leviton, Amazon Alexa, Google Assistant, Apple Siri, IFTTT, Matter

Lutron Smart Dimmer Starter Kit

True rocker switch with sliding dimmer

Excellent compatibility

No neutral wire required

No smart features without hub

Only one switch included

No Matter support

If you're ready to invest in a full smart switch environment across your home, Lutron's Caseta platform is a trusted choice, and the Diva Smart Dimmer Switch Starter Kit is a great way to jump in. A big advantage of the bundle is that it comes with the Lutron Smart Hub that the local wireless system operates on. It's an extra piece of equipment that needs to stay cabled to your router for smart features to work, but it lets you easily add other Lutron switches, without a neutral wire or having to connect each unit to Wi-Fi. Besides making app control possible, the hub offers compatibility with more smart platforms and voice assistants than most switches do, even without any plans to add Matter compatibility. 

Also included in the kit is a Pico smart remote that serves as another control point—some versions come with a pedestal to set the remote onto, while others provide a wall plate for mounting the remote to your wall like a three-way switch. For the switch itself, the original Caseta switches used a multi-button design much like the remote, but the newer Diva style opts for a more conventional paddle/rocker that fits more naturally with most homes' aesthetics. The dimmer function , too, forgoes buttons in favor of a slider with a thin LED bar to indicate the current brightness level. 

Connectivity: Lutron Clear Connect RF | Switch Style: Rocker switch with dimmer slider | Circuit Type: Single-pole | Control Method: Lutron app, Amazon Alexa, Google Assistant, Apple Siri, Samsung SmartThings, Ring, IFTTT, remote control

Best with Motion Sensor

Ge cync dimmer + motion sensing smart switch.

No neutral wire or hub required

Bluetooth pairing with Cync bulbs and multi-location switches

Adaptor needed for loads under 15 watts

Unconventional switch design

Devices like the Dimmer + Motion Smart Switch from GE's Cync smart line combine capabilities that make a lot of sense together. By using a motion sensor as well as ambient light detection, the switch can determine whether someone's in the room or not and turn the connected lights on or off accordingly. It automates your lighting even more intelligently and potentially saves you on energy costs. Dimming, too, is built into the switch, designed with a circular primary button and brightness up and down buttons above and below it (which may not suit everyone's decor tastes).

Another significant advantage of the switch is that a no-neutral version is available for locations without neutral wiring. No hub is required, either; this model utilizes just three wires for line, load, and ground. It does, however, require a minimum of 15 watts total across the bulbs at the switch. LED lights often fall below this threshold, so if they don't add up to 15 watts, you'll need to screw on the included bulb adaptor. Once the switch is installed, it connects to the Cync app via Wi-Fi, as well as uses Bluetooth to pair with GE Cync smart bulbs that aren't on the same switch and with other similar switches for control from multiple locations.

Connectivity: 2.4GHz Wi-Fi, Bluetooth | Switch Style: Single button with dimmer and motion sensor | Circuit Type: Single-pole | Control Method: Cync app, Amazon Alexa, Google Assistant

Our best overall is the TP-Link Kasa Smart Wi-Fi Dimmer Switch KS225 because of its effective design, simple installation, intuitive app controls, and excellent cross-platform compatibility and potential through Matter. For those willing to commit to a specific smart lighting control platform, the Lutron Caseta Diva Smart Dimmer Starter Kit (our best kit pick ) provides a well-designed switch, a remote that doubles as a movable three-way location, and a hub that powers the ecosystem's connected features and wide compatibility with leading smart home brands. 

What to Look for in a Smart Switch

Switch type.

The basic type of switch you can replace with a smart model is a single-pole switch that turns your lights on or off from a single location. Many smart switches also function as dimmers to adjust the brightness of your bulbs, and some come equipped with motion sensors to detect if a person is in the room. 

Today's smart switches are generally not designed in the classic toggle style that flips up and down, instead using buttons for the on/off or dimming functions. Some models replicate the paddle or rocker style of switch, where they still operate through buttons but visually blend better with home design styles more people are familiar with. The original Lutron Caseta switches, for example, used a busy combination of buttons, but the brand now offers a more contemporary smart switch design as found in our best kit choice, the Lutron Caseta Diva Smart Dimmer Starter Kit .

Device Compatibility 

Compatibility with other smart home systems is a key consideration with smart switches. The manufacturer's own mobile app usually handles core controls like dimming and scheduling, but a lot of a smart switch's conveniences draw on integration with other devices. A switch's compatible smart platforms determine what products it can interact with, how you can issue voice commands , and more. 

Amazon's Alexa and Google Home (and its Google Assistant) are the most commonly supported ecosystems; fewer devices tend to work with Apple Home and the Siri virtual assistant. But select smart switch models like our best overall pick, the TP-Link Kasa Smart Wi-Fi Dimmer Switch KS225 , and our best dimmer pick, the Leviton Decora Smart Dimmer Switch, Wi-Fi 2nd Gen D26HD , also support the new Matter standard for universal compatibility across leading platforms. You'll want to coordinate your switches with the ecosystems you currently use or soon intend to, which can take some planning.

"Consider the overall use of your smart switches," says Johann Whitehouse of WH SmartHome. "Are you going to do just a couple throughout your house and don’t mind having a separate app to control them? Or do you plan to integrate everything in your home into a single app? This will determine how robust the brand of switches has to be."

Programming Options 

Besides live app and voice control of your light fixtures, smart switches let you program custom schedules and timers for turning lights on or off on their own. The Leviton Decora Smart Dimmer Switch, Wi-Fi 2nd Gen D26HD , our best dimmer choice, has particularly detailed programming options, including sunset- and sunrise-based scheduling. Most smart switches include a vacation mode that randomly activates your lighting to make it appear like you're home, even while you're away. 

You can also set up automated scenes or routines that work together with other switches and smart devices, often within the brand's own ecosystem or a compatible one like Alexa or Google Home. Switches that support IFTTT (If This, Then That) open up the potential for even more customizable automations or applets that coordinate between a variety of third-party products and services. 

Installation Requirements

One of the first things to check for is whether neutral wiring (often color-coded white or gray) is present at the location where you want to install your smart switch. This may not be the case for older homes, particularly if those built before the 1980s. Many smart switches will specify that they require a neutral wire, which serves to deliver a constant bit of power to keep the switch wirelessly connected even when your light fixture is off. If you don't have a neutral wire, look for no-neutral switches, which often connect through a separate hub rather than directly to Wi-Fi. Our pick for the best with motion sensor , the GE Lighting Cync Dimmer + Motion Smart Switch, No Neutral , is an option that allows for installation without a neutral wire or a hub, making it even more simple to set up.

In terms of other electrical factors, the majority of smart switches are designed for single-pole switches with 120-volt circuits , so they should be fine as long as you're not trying to control double-pole switches and higher electrical loads. An important distinction, though, is whether you're connecting to your lights from just a single switch or using three-way or four-way switches to control the same fixture from two or more different locations. "Make sure to know if the switch/dimmer supports three-way installations," Whitehouse says, "otherwise your lights with two switches controlling it will not work. Not all smart dimmers/switches support three- or four-way applications.

For more advanced fixtures, he adds, it’s also important to consider the dimming phase the fixture requires (forward vs. reverse) and ensure the dimmer will be compatible.

Smart switches will draw a small amount of electricity in order to stay connected to your network and be ready for your commands, but not enough to make a big impact. 

"It would be so minimal, I'm not sure it would have any significant load to it," says master electrician Ryan DalPezzo. "I wouldn't say smart switches save energy; they would be about the same as a regular on/off switch." He suggests that the kind of light bulb used, such as LED rather than incandescent, would help save energy instead.

Generally speaking, yes, as long as you're replacing it with a compatible type of switch and meeting the electrical requirements at the location, which tend to be standardized across the switch market. 

"Most homes have 120 volts for their lighting, and most switches would be rated for that," DalPezzo says. "A big thing is your wattage, and what your LED bulb's wattage is. You can have a lot of bulbs with low wattage and no issue with overloading the switch."

Smart switches usually come with relatively straightforward installation steps designed for homeowners to follow, involving connecting a few electrical wires and mounting the hardware to your wall. Depending on your needs and your home's current electrical setup, however, the process can quickly become complex or require some troubleshooting. Contact an electrician any time you're beyond your comfort zone—when live electricity is in play, you could start risking the safety of yourself or your equipment. 

"Work safe, keep the power off, and be careful," advises DalPezzo. "Check your connections. With some brands, you need to specify your line (which is power in) and load (which is power out to the light). Make sure you have those oriented correctly or it won't work.

"I'm not opposed to people giving things a shot," DalPezzo adds. "But if it doesn't work right, then call a professional. It can be less expensive if you call a professional right away, before you burn out your equipment."

With the popularity of our Laser Trip Sensor we designed the Wireless Trip Sensor for 2003! We combined a very low power sensor along with a powerful UHF transmitter that can send from over 300 feet away. Each transmitter and receiver can be set for their individual code, allowing you to protect various 'zones' and tell you which zone was violated! The source is generally placed near a continuous power source and the remote transmitter can be placed anywhere without running any wires. The transmitter is typically effective for up to 600 feet. The WTS1 will constantly look at the ambient light in the room or area you wish to protect, and sense any blockage of the light. Once that happens, it sends its wireless signal to the matching receiver to alert you! No definitive trip paths and no wires!

The sensor/transmitter mounts in a standard piece of 1½” PVC pipe (included) for easy and inconspicuous mounting. Being battery powered, there are no wires or plugs attached. The receiver includes a visible LED alarm as well as a built in audible alarm. Once tripped, the alarm remains on until it is reset by the front panel reset switch. Transmitter and receiver work at 433MHz and are designed around our proven RF modules. Receiver includes a built in wire whip antenna and the attractive black custom case set shown.

The transmitter operates on four AA batteries (not included) and the receiver runs on 9-15 Volts DC, or our AC125 power adapter (optional). Case size 5”W x 1½”H x 5¼”D. Find out when someone goes into that room today, with the Wireless Trip Sensor.

Best Network Switches: Add Ports, Speed and Versatility to Your Network

We tested several network switches to help find the right one for your needs and budget.

Best Network Switches

As home networks get more complicated (and packed with more wireless devices) wired networking starts to feel almost dated. Who needs a wired connection from one of the best network switches when you can get Gigabit speeds or better from one of the best gaming routers ? 

But a wireless connection introduces several variables. Protocol compatibility, interference, signal-obliterating wall materials, or even poorly-designed radios and antennas can slow a speedy gigabit connection to a comparative crawl. For much more on this, see our how-to choose a gaming router feature.

Conversely, a good wired connection can cut out these and other shortcomings of an over-the-air signal, while providing faster speeds and a reliable, stable connection. But with most mainstream routers only offering just four Ethernet ports -- or sometimes fewer -- the best network switches step in to fill the gap, giving you more ports to plug your wired devices into. Not only that, they can also spread out some of the load on your network, freeing your router up to carry out its primary mission of getting internet service to all the wireless devices on your network that need it.

Like the Ethernet hubs that came before them, one of the best network switches can add several ports to your network, letting you plug in more devices to your network than would otherwise be possible using the router's limited number of built-in ports. 

What’s more, the best network switch can filter your LAN traffic, moving prioritized packets to the front of the line to keep things like games or 4K HDR streams running smoothly. And most normal networks don’t require more than the simple solution of an unmanaged switch. We did some hands-on testing with several different (mostly unmanaged) network switches to see which ones are the best for most people. This is by no means an exhaustive list, but these network switches perform well and are solid options for each given use case. 

Shopping Tips for Best Network Switches 

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test .

When looking for the best network switches, consider:

Number of Ports: You can get anywhere from four all the way up to 48 or more Ethernet ports. Some also have USB ports.

Managed or Unmanaged: If you just need to get wired internet access to a few devices, then you’ll want an unmanaged network switch, which we recommend for most users. This doesn’t mean the switch has no features -- unmanaged switches can often do plenty of fancy things, from traffic prioritizing QoS to loop detection. 

Managed network switches are more secure and can monitor traffic for troubleshooting purposes or separate chunks of your network into their own virtual local area networks, or VLAN. If going this route, you’ll also want to make sure your router is compatible with VLANs -- a non-bridged setup using Amazon ’s eero mesh routers, for instance, makes VLANs unusable.

Power Needs: Most won't need it, but certain devices can get power over Ethernet if your switch supports it. 

Network Speed: Gigabit Ethernet is the minimum speed, but you should consider going with 2.5 GbE or higher, even if you don't need it right now, because future devices may benefit. 

Best Network Switches You Can Buy Today

1. tp-link tl-sg108 (unmanaged).

Our expert review:

Specifications

Reasons to buy, reasons to avoid.

When it comes to 8-port network switches for the home or small office network, it’s hard to beat the TP-Link TL-SG108. It’s compact, has a fanless metal enclosure, plus dimmer-and-less-distracting LEDs than some of its competitors (Don’t worry; there are still two per port, each informative based on color and/or blinking pattern). The TL-SG108 also features traffic-prioritizing QoS, full duplex flow control, auto-negotiating ports for choosing transfer speed up to a gigabit, and simple, plug-and-play setup. This best network switch performed at rough parity with other 8-port switches we tested and ran cool.

The one notable omission from this network switch is loop detection, which prevents your network being slowed to a crawl or disabled entirely by looped network traffic. This can be a very important troubleshooting tool in a complicated network, with visual indicators on a switch that tell you which Ethernet ports to investigate for issues. 

If loop detection is a requirement, we recommend either the ProSAFE Netgear GS108 or the Cisco CBS110-8T-D . However, each of those switches, at $40 and $68 respectively, is also significantly more expensive than the less-than-$20 TP-Link. And we do not feel that, for most people, loop detection justifies the extra cost. 

Lastly, the TP-Link features a nice limited lifetime warranty, providing a nice peace-of-mind that you wouldn’t get from, say, the similarly-inexpensive Netgear GS308, which only has a 2-year warranty. On the whole, even if you only need 5 extra ports, we recommend this switch for its price, feature set, and build quality to expand the wired capability of your network now and in the future.

2. TP-Link TL-SG105-M2

After what seems like an eternity, network devices are finally beginning to embrace faster-than-gigabit connections. From routers to modems, computers to NAS, big data pipelines are starting to enter the mainstream. And that’s a good thing, particularly as we now use more data than ever before. It’s even possible to get a 2 Gbps connection now if you live in one of the cities where Google is now offering the service .

Of course, you needn’t have a connection that fast to get use out of one of the recent 2.5 GbE network switches. File transfers, home media servers, and high-capacity, high-bandwidth NAS setups can all stand to benefit from a high-bandwidth switch, and as they come out, we’ll try to put our hands to the latest and greatest to let you know how they fare. That brings us, today, to the TP-Link TL-SG105-M2: a super fast unmanaged 5-port, 2.5 GbE switch that, while bigger than your average 5-port gigabit switches, should still fit into just about anyone’s setup - and budget, for that matter.

Along with its 8-port sibling - the TL-SG108-M2 - the TL-SG105-M2 is low-profile, easy to set up, and features a fanless design and metal enclosure that will keep it as quiet as it is fast. And because it’s a 2.5 GbE switch, you might not need to buy new cabling; as long as you’re already using Cat 5e cabling in your network, you’re good to take advantage of the 802.3bz network protocol, which promises 2.5 GbE or 5 GbE connections over 100 meters of cable. In testing, this bore out, with super fast file transfers that didn’t even blink when we loaded the network down with as much traffic as we could muster. The switch ran a little warm though, topping out at about 115 degrees Fahrenheit.

This switch supplants our previous choice for best 5-port switch, the QNAP QSW 1105-5T, for a few reasons. First, the TP-Link just has a bigger pipe for data, pushing a consistent 2.34 Gbps where the QNAP, in our testing, only barely got over 2 Gbps in real world use. It also has a slightly more space-friendly form factor. And perhaps most importantly, where the QNAP’s warranty ends at 2 years, the TP-Link TL-SG105-M2 falls in the company’s business class of switches, giving it a generous limited lifetime warranty. Lastly, the TL-SG105-M2 sports QoS - a feature typical of most unmanaged switches that is conspicuously absent on the QSW 1105-5T. 

If we had to pick a couple things that aren’t ideal about this neat little switch, it would have to be the lack of loop detection, and the fact that the power supply plugs into the side opposite the ports -- of course the latter is entirely personal preference, but it can also complicate installation in some setups. The TP-Link’s list price is $129.99 - although as of the time of this writing, you can actually get it for $109 at Amazon , which is the same price as the QNAP. The TP-Link is the choice either way, but with the current price, it’s a no-brainer.

3. Ubiquiti Unifi USW-Flex

This is a complicated recommendation. Recent news concerning a privacy breach at Ubiquiti notwithstanding, we believe the Unifi USW-Flex to be the best network switch for anyone looking to bring PoE to the edge of their network. This affordable, 5-port wonder can supply up to 15.4 watts of power to each of its four output ports. Note the use of “up to” here; once you’ve got all ports occupied, the 46-watt power budget will prevent 15.4 watts going to all four ports at once. So if you are using up all of that power at every port, the fourth port gets reduced priority and lower wattage. The PeE features also only apply provided the Unifi USW-Flex is powered itself by a proper PoE injector. If you’re uncertain which injector to buy, Ubiquiti sells a fairly inexpensive one . 

Although it’s a managed switch, the Unifi USW-Flex lacks certain key features like Spanning Tree Protocol, which helps prevent switch loops, or the ability to use SSH for extensive command-line-management (although you can SSH in for some basic functionality like firmware updates), it works well as an edge-of-network device to power things like IP cameras or sensors that you may want to have minimal wiring going to.

Additionally, the USW-Flex is built for outdoor use and comes with multiple mounting options - either magnetic or pole/wall mounts - as well as a hood that can be affixed over the Ethernet ports to help prevent moisture ingress when it rains. As a quick aside, part of this switch’s outdoor-friendly design is its recessed ports, which can be hard to remove an RJ45 connector from, as there isn’t much room for your fingers to squeeze the connector’s release clip.

In testing, we found that, when using the Flex without configuration, it worked about as well as any other in this list: Transfer speeds were solid, and faster than other gigabit switches tested under load. It’s worth noting here, however, that the Ubiquiti does get quite hot, sitting easily over 100 degrees Fahrenheit at idle and getting as warm as 118.7 degrees F with every port in use --  and that’s in a cool room, with plenty of air movement. It’s rated to operate in temperatures up to 149 degrees F (at 25W output - 131F at 46W), but it would still be a good idea to keep it in a shaded area if using outside, as direct summer sun could shorten its lifespan or impact performance. 

The USW-Flex comes with other caveats, too. The switch is managed via a browser-based GUI (the same general-purpose interface that is used for all other UniFi gear, which is nice if you have an all-UniFi network, but irritating and confusing if you only have this switch. And though it can function without ever touching its settings, there are some you’ll have to change to access promised capability. For instance, the switch does not default to the 802.3bt protocol that provides for the full 46-watt power budget, so you must change the power source under settings to PoE Injector. 

You’ll want to be certain that the device powering it is outputting with the 802.3bt protocol, or you will not be able to get all 46 watts. The final note is applicable to managed switches in general: If setting up and using a virtual LAN, you would do well to first ensure that your router supports VLANs -- Amazon’s eero, for instance, currently does not. In spite of all of this, the convenience of bringing both Gigabit Ethernet and 802.3af PoE power from four ports to anywhere in-or-out of your home for a hundred bucks is quite a weighty item in the “pro” column in our opinion.

4. Zyxel XGS1010-12 (Unmanaged)

In between 8-and-16-port switches, you have some funky units like this ZyXel XGS1010-12. It’s billed on the box as a desktop switch with 8 gigabit ports and four bonus ports in the form of two 2.5 GbE and two 10 GbE SFT+ uplink ports. The latter fiber Internet customers would recognize as the data port on a fiber ONT (Optical Network Terminator -- think of it like a Fiber modem for customers without last-mile copper). 

Physically, the XGS1010-12 has a solid metal enclosure, a fanless design, an external power supply, with all the ports on one edge while the power supply connects in the back. Each port has two LEDs for power and status, with colors to indicate the speed of connection being provided. It boasts QoS, Auto MDI/MDIX in all ports, and flow control.

The switch did well in testing, putting up numbers slightly better than the QNAP on its 2.5 Gb ports, while its gigabit ports performed very well. Under heavy traffic, we saw no performance loss, which is to be expected given its total bandwidth of 66 Gbps. The ZyXel was the second-hottest of the switches tested, peaking at 100 degrees Fahrenheit under load - which is definitely going to be warm to the touch, but not concerningly so. Just make sure the box has a bit of ventilation. 

Though the ZyXel XGS1010-12 will run you $150 when bought at its MSRP, the addition of two 2.5 GbE ports and two 10 GbE SFP+ uplink ports makes this a very good deal relative to similar switches, which typically go for hundreds of dollars and lack this much versatility. If you have a high-speed NAS or need a super-fast connection between a couple of your computers, this switch lets you do that on the cheap, while still serving as a great hub for your other devices. 

Lastly, it is somewhat unclear what the warranty terms are for this switch (the included documentation only refers the buyer to the website, where it’s not explicit under which warranty it falls, Standard or Limited Lifetime). But we contacted Zyxel and were able to confirm that while XGS1010-12 falls under the 2-year Standard Warranty, this particular switch is among those that have had their term extended to 5 years. That still isn’t amazing, but it’s better than what you’ll get from many cheap switches.

5. TP-Link TL-SG116

TP-Link is once again a best network switch choice here because of its affordability. At $50 it’s not quite as much a deal as the TL-SG108, but finding a lower-cost 16-port unmanaged switch with the kind of reliability, warranty, and proven performance offered by TP-Link would be challenging and perhaps involve some good fortune. 

With the TL-SG116, you’ll get the same benefits as the 8-port version: IGMP snooping, flow control, QoS, etc. It also has the same unobtrusive LEDs, metal housing, and fanless construction and limited lifetime warranty. Like its 8-port sibling, however, it lacks loop detection, which may be a bigger issue when you’re the type of user looking for a 16-port switch.

The TL-SG116 performed as well as can be expected in testing, with a small drag in transfer speed under load, but otherwise maintaining at least near-gigabit speeds while testing with iperf and normal file transfers, streaming, and gaming. If you have more complicated network needs, we recommend the D-Link DGS-1100-16V2 Easy Smart Managed Gigabit desktop switch, which features an approachable GUI management interface and a well-rounded feature set for $109.99.
