Smart plugs, also known as smart outlets, are one of the best smart home devices out there. These compact devices fit into traditional wall sockets and can be installed in a matter of minutes, giving everything from your bedside lamps and living room TV to small appliances like dehumidifiers and coffee makers a new way to operate.
Here at Reviewed, we’ve been testing smart plugs for years, looking for important details like connectivity, energy monitoring, and enhanced privacy settings, and scheduling features. After a new round of testing, the Wyze Smart Wi-Fi Plug(available at Amazon) is our top pick for the best smart plugs. While it doesn't offer energy monitoring, it is one of the only smart plugs we tested that offers two-factor authentication, an important feature that helps to keep your smart home safe and secure. But there are plenty of great plugs on our list to pick from.
These are the best smart plugs we tested, ranked in order:
Wyze Smart Plug
Geeni DOT Smart Wi-Fi Outlet Plug
TP-Link Kasa Ultra Mini
Amazon Smart Plug
Philips Hue Smart Plug
Meross Smart Plug Dual Wi-Fi Outlet Plug 2-in-1
Meross Smart Wi-Fi Plug Mini
Leviton Decora Smart Wi-Fi Mini Plug-In Switch (2nd Gen)
Sengled Smart Plug Outlet
Wemo Smart Plug
Wyze Smart Plug
After testing the Wyze Smart Plug for the better part of a year, we are confident it’s the best smart plug you can buy—for a variety of reasons. It maintains a strong and stable connection to help control your devices whether you’re sitting on the couch or the other side of the world, and the setup process is a cinch. It’s also one of the only smart plugs in our guide that offers two-factor authentication, an important security feature that alerts you immediately when someone tries to gain access to your account, and a shared device user list to help you keep tabs on who has access to your plug.
We didn't run into any issues when using the Wyze app with Amazon Alexa, or Google Assistant to control this smart plug. HomeKit users may be disappointed to find that there is no support for Apple’s Siri but that’s not uncommon in the space. Overall, Wyze’s smart plug was responsive to our voice commands and in-app controls.
The plug offers scheduling and automation features, as well as a timer. There's also a special setting called Vacation Mode, which can turn your devices on and off at random times to give the appearance that someone is home.
As for design, this compact 15 amp model looks like most others with its front-facing socket and rectangular design that doesn’t block the second outlet. There’s a power button on the side, for when you need to physically control the plug, and the LED status light on the front is a handy visual cue that relays the plug's power status.
The plug doesn't offer real-time energy monitoring, but the app tracks the daily and weekly runtime for the plug to help give you a sense of your average energy usage. Wyze may still be carving out a name for itself in the smart home space, but this smart plug packs a big punch, offering exceptional value for any Alexa or Google-enabled smart home.
Hi, I’m Rachel Murphy, Reviewed’s smart home staff writer. I live in a smart home that’s full of smart cameras, smart speakers, and more. During my tenure at Reviewed, I’ve tested video doorbells, smart coffee makers, and other gadgets that can be controlled remotely or via smart assistants such as Amazon Alexa and Google Assistant.
Our previous tester, Monica Beyer, has been writing about tech for over a decade. She's an Amazon Alexa user and lived with (and extensively used) some of these plugs for a couple of months to get a full feel for how they'd be used in a typical smart home—and how well they worked.
Since we originally published this guide in 2016, many new controlled plugs have come on the market. Browse the smart home section at Amazon and you’ll find a cornucopia of outlets from no-name brands, many of which feature identical specs and near-identical looks. We regularly update this guide to assure the picks are the best on the market and check out the latest newcomers to the space.
Our tests start by setting up each plug using both Android and iOS, taking note of any difficulties in the installation process. Once up and running, we put the plugs through their paces, testing their apps, smart home integrations, reliability, range, and responsiveness. We explore each app for security features like two-factor authentication and take into account what types of user data (and how much of it) the companion apps collect. We test each plug over a Wi-Fi network as well as using a remote data connection. Where available, we check to see if their energy consumption results were in line with the pack. We also note any differences between features on Android and iOS, since we think everyone should enjoy the same perks. Finally, we judge each plug on its looks and ergonomics since you’re probably going to be looking at and interacting with these things for a long time to come.
What You Should Know About Smart Plugs
Whether you use Alexa, Google Assistant, or Siri, it’s important to make sure the smart plug you choose works with your preferred smart assistant. It may seem obvious, but not all plugs play nice with all assistants.
Many connected plugs work with both Alexa and Google Assistant, but that’s not always the case with Apple’s Siri. To avoid any surprises or headaches, look for a smart plug that’s compatible with the smart assistant you use the most. Compatibility information can be found on the product’s page or the exterior of the product’s packaging.
These connected outlets can do more than give you remote and voice control for your not-so-smart devices—many can also monitor how much energy your connected devices are using. These details can usually be found in the smart plug’s companion app and will tell you how many kilowatts the smart plug is using each hour, day, month, or year.
While energy monitoring isn’t a make or break feature and it won’t impact your ability to use a smart plug, it can help give you a clearer picture of how much energy your connected devices are using and help you identify areas to reduce your energy consumption. This may save you money on your monthly electric bill and help you develop more energy-efficient habits at home.
Smart plugs come in all shapes and sizes. Before you buy one, consider where you want to put it. A slender, rectangular plug likely won’t block the second outlet on a wall panel, no matter where you plug it in. Most of these smart plugs are meant for indoor use only, but outdoor smart plugs are an option, too.
There’s always a potential privacy risk involved when you use internet-connected devices at home. To help safeguard your smart home, there are some steps you can take. First, look for devices that offer two-factor authentication, which sends a code to your mobile device to verify it’s you. That way, if someone tries to hack into your account, you will receive an alert and can quickly take care of the problem. Many devices also allow you to activate email or other push notifications in the settings to alert you if someone has logged on.
Additionally, make sure to use a unique, strong password composed of multiple characters, numbers, and letters for each of your smart home accounts. Data breaches feel like the norm as of late, making it all the more important to use different passwords across multiple websites and apps.
The Geeni Smart Dot is a front-facing, circular smart plug that works with voice assistants like Alexa, Google Assistant, and Microsoft Cortana (but not Siri). The setup is simple and we didn't run into any hiccups during use. The plug’s design doesn’t block the second outlet, but it is large enough that you won’t be able to plug two of these stacked on top of each other like you can with many rectangular-shaped smart plugs.
Geeni offers in-app security features like two-factor authentication and a list of shared device users, to help keep unauthorized users at bay. The plug is only compatible with 2.4 GHz Wi-Fi networks and does not require a hub. You can control this plug using the Geeni app, which is responsive and user-friendly, as well as voice control with compatible smart assistants like Alexa and Google Assistant. It’s rated for 10 amps (most plugs are rated for 15 amps), so make sure not to overload the outlet with too much power.
From smart bulbs to outdoor plugs and indoor cameras, Kasa makes a lot of smart home devices that work with Alexa and Google Assistant. Adding to its impressive lineup is the ultra-compact Kasa Smart Wi-Fi Mini Plug. Measuring less than 2.5-inches long, it's one of the smallest products we've ever tested—and you can easily stack several of these plugs without blocking the second outlet.
It doesn't work with Siri, but voice control with Alexa or Google Assistant worked well every time we tried it. The plug is rated for 15 amps, so you can plug in any small home appliances like dehumidifiers and standing fans. Features like smart schedules, grouping, remote control, and an auto shut-off timer are available in the Kasa app and work great.
Though the app doesn’t have security features like two-factor authentication, it offers daily, weekly, and monthly insights into how many hours the plug remains on. It’s not as helpful as in-app energy monitoring stats, but the data is useful enough to help curtail your energy consumption.
Amazon has its own smart plug that works exclusively with Alexa. So, in other words, it will not work with Google Assistant, Apple’s Siri, or any other smart ecosystem. We had a difficult time getting it going, even though it doesn't need a third-party app—Alexa just didn't recognize the plug the first time and we had to try again.
Once it connected, though, it was flawless. It integrated painlessly with Alexa, had no problems connecting and disconnecting, and it was simple to control with both the Alexa app and via voice controls with an Amazon Echo speaker.
Aside from the initial setup issues, the Amazon Smart Plug works great. Of course, those who don't use Alexa-enabled devices should look elsewhere.
We’ve been a fan of Philips Hue, maker of some of the best smart bulbs we’ve ever tested, for a while now. So we expected good things from Philips Hue’s smart plug—and it delivered. The plug maintained its connection throughout our weeks of testing and was able to easily reconnect to Wi-Fi when switching outlets. It’s compatible with Alexa, Google Assistant, and Apple HomeKit.
The app doesn’t offer any special energy monitoring capabilities, but there are plenty of other useful features to choose from within the Philips Hue app, like routines and timers. You can also elect to share your location with Philips Hue so that your plug automatically turns on and off as you come and go. Overall, this plug is a good option for anyone who is already running a Philips Hue ecosystem at home.
Works with Apple HomeKit, Alexa, and Google Assistant
Need a space-saving smart plug that offers two independently controlled outlets? That’s exactly what you’ll get with Meross’ dual-outlet smart plug. It’s also a very versatile smart plug when it comes to smart assistant control because it works across the big three: Alexa, Google Assistant, and Apple’s Siri. However, an Apple Home Hub like the HomePod Mini is needed to control the plug using Siri when you're away from home.
The dual-outlet model can also be controlled using the Meross app, which is simple to navigate and works well for remote control. There’s also a noticeable “click” sound that happens every time the plug is powered on or off. It’s not loud enough to wake the neighbors, but it’s louder than your average smart plug and therefore something to note before you buy.
Unfortunately, the plug does not offer two-factor authentication for added security. It’s also only rated for 10 amps, so make sure it can handle the load of whatever you’re plugging into it.
Meross makes fantastic outdoor smart plugs, so we were eager to try the company’s indoor smart plug, the Meross Wi-Fi Smart Plug Mini. The tiny white plug never lost connection during our tests and was fast and simple to get up and running. We found the app to be very user-friendly, too, offering ways to create scenes and routines that can automate your home.
On the downside, the 16-amp plug doesn’t offer any way to track how much energy a device is using or how long it’s been on. It also doesn’t offer two-factor authentication to secure your account.
However, this indoor smart plug is reliable and responsive when controlled remotely using the Meross App or via voice assistants like Google Assistant and Alexa. It also supports IFTTT, and Samsung SmartThings.
Leviton Decora Smart Wi-Fi Mini Plug-In Switch (2nd Gen)
Leviton's 15-amp second-gen model works seamlessly across the three major smart assistants: Alexa, Siri, and Google Assistant, which is fairly rare for a smart plug. The setup is simple—it took mere minutes to connect the plug to Wi-Fi and integrate it with compatible voice-activated smart assistants. If you want to control this plug away from home using Siri, you’ll need an Apple HomeHub like the HomePod Mini. It also doesn’t block the second outlet no matter what position it’s in.
One noticeable difference between the first-gen plug and the second-gen plug tested here is the added support for Leviton’s DAWSC Anywhere Companion Switch. When using this model, you can place the wireless Anywhere Switch within 50-feet of the plug and use the switch to turn it on and off—no wires required.
While there are plenty of pros about this plug, there is no two-factor authentication offered in Leviton’s app, reducing security. The plug also lacks energy monitoring or any other usage insights. But, if you need a smart plug that works great with Alexa, Google Assistant, and Siri, the Leviton Decora Smart Plug-In Switch is a fantastic choice.
Sengled’s Smart Plug requires a hub, which isn’t the norm for most smart plugs. We paired it with a Samsung SmartThings Hub and it connected easily within seconds, but any Zigbee hub like the Echo Show 10 will do.
One bummer about this smart plug is the design. While we like that it’s a break from the traditional white rectangular shape of most smart plugs, the square design ever so slightly blocks the socket immediately above (or below) the plug. This shouldn’t be much of an issue if you’re using a regular corded plug, but the design doesn’t allow for two smart plugs to be stacked on top of each other. It also does not offer energy monitoring or two-factor authentication for increased security.
Overall, the Sengled plug is responsive when used with Alexa and Google Assistant, easy to use via the Samsung SmartThings app, and it offers a steady connection even when moved from room-to-room. The app, like other smart plug apps, offers scenes, schedules, and more ways to automate your smart home. It’s a fine smart plug, but not the best if you’re looking for extra outlet space or enhanced security.
We were excited to try out the Wemo Smart Plug, as it’s one of the rare few that works with Alexa, Google Assistant, and Apple’s Siri. It also is one of the most compact smart plugs we’ve seen, making it ideal for small spaces and crowded outlets. To control the plug using Siri when you’re not home, you will need an Apple Home Hub like the HomePod Mini.
However, this plug struggled to maintain a steady Wi-Fi connection, often disconnecting randomly for no reason. A smart plug should be reliable, especially for remote management, and Wemo’s did not deliver on that front. It also does not offer two-factor authentication or energy monitoring, and is only rated for 10 amps.
When this plug works, it works well, but given the connectivity issues we had, you’re better off selecting a more reliable plug from our guide.
