Make your gadgets smart with these handy products
The smart home is increasingly commonplace, with smart thermostats, connected smoke alarms, colour-changing light bulbs, voice-controlled speakers and much more.
But the main entry point to this world is through a simple but important accessory: the smart plug.
With the smart plug, you can make a “dumb” gadget smart. For instance, use it for the bedside lamp so instead of struggling across a dark room with your hands full, say, “Alexa, turn on the bedside light”.
Alexa is Amazon’s voice assistant, though you can also say “Hey, Google” or “Hey, Siri” for products that respond to Google Assistant or Apple HomeKit smart home set-up.
Not all gadgets get really brainy. Some kettles still need you to press a button before they start working – so getting your morning brew going from the comfort of your bed may not apply.
We tested a range of smart plugs for set-up, simplicity of use, compatibility with multiple platforms, and efficiency in performance, and considered price and design as well. Note that a smart plug is adding an extra layer over the regular socket, and the bulk of some means they overlap two sockets on a multi-gang socket, for instance, or may not be suitable where space is cramped.
Best: Overall
The smart plug mini lives up to its name and is noticeably smaller than most here, so you can be sure it’ll only take up one socket in a power strip, for instance. As it’s HomeKit-compatible, a QR code is printed on the side of the plug. Scan that to simply connect it to your Apple device through the iPhone or iPad Home app. Meross warns that it only works with devices running iOS 13 or later, and emphasises that it’s more seamless with iOS 14. Otherwise, it’s a great versatile all-rounder, and reasonably priced, too.
Best: For Apple households
Eve energy is the best plug for anyone who has Apple products in their lives. It’s a well-built, highly effective gadget which works brilliantly with Apple HomeKit and its Siri personal assistant. To control the plug when you’re not at home you need an Apple Home Hub, in the form of either a HomePod or Apple TV, and you need an iPhone to use it. Thread compatibility has arrived recently with this latest version – thread technology is designed for smart home applications to improve connectivity so they are more robust and more responsive. It means that there’s no need for a central hub. Instead, compatible devices work together as a mesh network (the more Thread devices, the stronger the network).
The Eve companion app usefully measures energy consumption in tremendous detail. It even lets you work out how much the product you have plugged in is costing, if you enter your supplier’s rate in.
Best: For multiple devices
There’s no issue with overlap here because this power strip has a regular-sized plug. The smart components are contained near the three sockets. There are also two USB sockets, too. Each regular socket has its own smart control so you can use them for regular plugs, too. The Kasa app helps you set the power strip up and includes energy monitoring as well. Of course, you may not have three gadgets which you need to make smart which will naturally sit next to each other, but if you do, this is a great solution.
Best: For size
The Philips smart plug is small and efficient, not much bigger than a regular plug. If you own other Philips Hue devices, you’ll likely have the Hue Bridge – that is, the hub that’s needed to control the bulbs in most circumstances. If so, you can add Apple HomeKit compatibility to the Smart Plug’s capabilities.
Best: For Amazon households
An LED shows whether this smart plug is on, changing colour and blinking when setup is in progress or if there’s no network connection, for instance. Where other plugs are platform-agnostic, this is designed exclusively to work with Alexa, Amazon’s voice assistant. There’s no microphone in the plug, of course, so you speak your commands to either a separate Alexa-capable device such as an Echo speaker or the free Amazon Alexa app, available for Apple and Android smartphones. It’s quite big but the shape is vertical so it shouldn’t overlap with adjacent wall sockets.
Best: For value
TP-Link’s Tapo app is a simple way to set up this smart plug and it has plenty of features, such as an away mode which can turn devices off and on so that it seems somebody is at home or to create a countdown until gadgets turn themselves off. The plug is compact enough to avoid spilling over to an adjacent socket but big enough to be easy to use, for instance to easily access the power button on the left side.
Best: For indoor and outdoor use
Suppose the socket you’d like to make smarter needs to be outside, for garden lights, a sprinkler or seasonal decorations, for instance? This useful double socket makes that possible. A weatherproof housing protects the sockets, though it’s best kept under cover when not in use. It’s chunky and robust and while the design isn’t as attractive as some here, you’ll perhaps tuck it away out of sight. Of course, it works indoors, too.
Best: For price
This plug is better in an individual socket than an extension cable as it’s just that bit wider than some here, though a mini version is also available for £7 extra. But it’s effective and simple to use, with a clear LED telling you if it’s on or off. Set-up is not quite as simple as on some here but it works well. D-Link’s app is simple and wide-ranging. The plug usefully has two buttons, one for power, one for smart connectivity.
Eve energy is a real winner, with great performance, though its seamless fit for Apple devices means it’s best for households with an iPhone or iPad, while our overall best buy Meross homekit smart plug mini MSS110 combines compact size with strong capabilities. If you use Amazon Echo devices, the Amazon smart plug is hard to beat.
