Best Smart Plugs 2022: Turn dumb things into smart things

A smart plug is just about the most convenient and useful bit of kit that you can add to any smart home. From making a dumb light smart to controlling when your tools charge, a smart plug gives you control over devices that you’d normally have to adjust manually.

There are plenty of different types of plug available, from simple one-socket ones, to power strips that let you control multiple devices. Here, I’ve rounded up the best selection of each, so that you can find the right smart plug for you.

With a home full of smart technology, all plugs are tested for compatibility with all voice assistants and smart systems, such as IFTTT, so you can rely on this being the best choice.

How we test

Learn more about how we test smart plugs

We test smart plugs in the same way, so that we can compare different models from different manufacturers. For each plug we make sure that we connect it via all methods available. We also see how easy it is to plug in other devices next to the smart plug.

We have a host of smart home kit in our test lab, so we test smart plugs for compatibility with all types of smart system, including Apple Home, Amazon Alexa, Google Assistant, Samsung SmartThings and IFTTT.

A tiny smart plug with lots of features
rating-star rating-star rating-star rating-star rating-star


  • Very small
  • Doesn’t require a hub
  • Good app


  • No geolocation

An updated to the older smart plug, the TP-Link Kasa KP105 Smart Wi-Fi Plug Slim is a much thinner smart plug. In fact, it’s so thin that it won’t block any sockets if you use it in a double wall socket.

TP-Link’s Kasa app is excellent, giving you all of the features that you’d expect, including timers, schedules, an away mode (this randomly turns the plug on and off, so you can fake occupancy by, say, connecting the plug to a lamp). The only thing that’s missing is geolocation to trigger the plug automatically based on where you are.

However, you can add this feature using the IFTTT service. There are Google Assistant and Amazon Alexa voice control, and you can even hook the plug up to Samsung SmartThings if you want to control everything through there. Most importantly, this plug is really cheap, so what more could you want?

Philips Hue Smart Plug

The most flexible smart plug that you can buy
rating-star rating-star rating-star rating-star rating-star


  • Works with HomeKit
  • Excellent size
  • Can use without Hue Bridge thanks to Bluetooth


  • Slightly fiddly accessory setup

Designed to work with the Philips Hue lighting system, the Philips Hue Smart Plug can work with either Zigbee (if you have a Hue Bridge) or Bluetooth. The former is the best option, and we recommend this smart plug for those that have a full Hue system. There are two main reasons. First, Zigbee has better range and reliability than Wi-Fi and, secondly, if you have a network failure, you can still operate the smart plug using a Hue remote control.

Connecting to the Hue ecosystem gives this smart plug another advantage: it’s the only smart plug that we’ve tested that works with Apple HomeKit, so you can include this product in all of your automations. Otherwise, there’s Google Assistant, Amazon Alexa and IFTTT support.

Installation through the Hue app is a little fiddly and, if you just want to control this plug via a device, you’ll need to put it in its own room or Zone. If you don’t have Hue already, then one of the other products on this list will do a better job; if you do, then buy this one.

TCP Smart WiFi Plug

An excellent value smart plug, particularly when bought in a four-pack
rating-star rating-star rating-star rating-star rating-star


  • Decent app, particularly if you use Smart Life
  • Compatible with lots of other products
  • Excellent value as a four-pack


  • A little expensive for one

The TCP Smart WiFi Plug is tiny and won’t obscure a second socket, so you can even use it next to larger plugs. Its default software is pretty good, but this plug is compatible with the Smart Life app, which opens it to working with tonnes of other devices from lots of other manufacturers.

In the app, you get basic control, but you can add automations, making your plug work how and when you want it to. Smart Life also brings IFTTT, Amazon Alexa and Google Assistant compatibility.

While one of these plugs is quite expensive, they’re cheaper if bought in a two- or four-pack, making them excellent value if you need more than one device.

A handy power strip that lets you control three devices individually
rating-star rating-star rating-star rating-star rating-star


  • Convenient design
  • Powerful app
  • Great value


  • Short power cable

You can plug any multi-way strip into a smart plug, but what if you want to control multiple devices individually? The best way to do that is with the TP-Link Kasa KP303 Smart Wi-Fi Power Strip. This product gives you three individually controllable sockets all in one neat device, and you get two USB devices for charging, too. The main power cable is a little short but that’s our only complaint.

Controlled via the TP-Link Kasa app, each socket can have its own name and icon, giving you full individual control, including schedules and power toggling. Individual control spills over into other places, too, with Amazon Alexa, Google Assistant, SmartThings and IFTTT support.

More importantly, the price of this product makes it cheaper than buying three individual smart plugs and plugging them into an extension strip.

Eve Energy

A smart plug that monitors power consumption and integrates with Apple HomeKit
rating-star rating-star rating-star rating-star rating-star


  • Thread and Bluetooth
  • Works with HomeKit
  • Monitors energy usage


  • No Alexa or Google Assistant support
  • Quite chunky

If you control your smart home through the Apple Home app, then the Eve Energy may be the smart plug for you. It’s built for HomeKit and the future, with support for Thread, the new low-power wireless mesh networking protocol.

If you don’t have a compatible Thread border router, the Eve Energy will default to using Bluetooth. If you have an Apple Home Hub in range, such as the original HomePod, then you’ll be able to control the plug remotely when you’re not at home.

Although it’s comparatively big, the plug should fit into a wall socket without blocking a second one. You can add the plug using the Eve app, although it’s automatically added to HomeKit, too. There’s no Android app, so this is strictly an Apple-only product. Via the Home app, you can toggle the plug on and off, or include it in Automations, say turning it off when you go out. HomeKit support also means you get Siri control, so you can turn the plug on and off with your voice. Schedules are saved to the device, so they’ll run regardless of whether you have a HomeKit Home Hub.

With the Eve app, you can also monitor power usage. By setting the current price of your electricity in kWh, the app can tell you how much money it’s cost you to run the device plugged in.

What type of smart plug do you want? 

Smart plugs are available as either single plugs or as strips, with multiple individually-controlled sockets. The latter is a good choice if you’ve got multiple devices that you want to control close together.

What size plug is best for you?

Some smart plugs can be quite large, obstructing the second socket in a double socket. Our reviews tell you how big each smart plug is, so that you can find the right type for you.

What protocol do you need?

Smart plugs can work on multiple protocols, although Wi-Fi is the most common. With Wi-Fi, you just connect the plug to your home network, so all you need is a strong enough signal where you want to plug in. If you get a smart plug that uses a smart home protocol, such as Zigbee, you’ll need to have a compatible system, such as Philips Hue.

What integrations do you want?

Smart plugs are best when integrated into other systems. At a minimum, you’ll want your plug to work with Google Assistant or Amazon Alexa, so you can have voice control. Look out for SmartThings or HomeKit integration if you want to integrate your plug into routines. IFTTT support is also useful if you want to automate how your plug works.
