The possibility of what you can do with Alexa compatible smart plugs is endless, and features are growing rapidly – no more having to wait until you’re home to boil the kettle or warm your house up.

The final component, the smart radiator thermostat, is a white plastic cylinder, which fit to the radiator once the existing valve has been unscrewed. To manually override any schedules you may have set, simply swivel the top of the radiator thermostat right to start the radiator heating, or left to stop heating. An LED on the radiator thermostat glows red temporarily when the radiator is heating, and blue if it's been turned off. Turning and holding the radiator thermostat will also reset or put it into set-up mode, depending upon how long you hold it in that position.Powered by two AA batteries, the smart thermostat can be freestanding on a table or shelf, or mounted on a wall. It has three touch controls on the front. The plus and minus button allow you to adjust the desired temperature of the room, while the middle button boosts the heating in said room by two degrees. The screen automatically goes to sleep after 15 seconds to conserve the battery, but pressing any of the three touch controls will wake it up. The Heat Hub is a rectangular box with two buttons. One button activates the set-up process, while the other starts the whole system heating. LEDs above the buttons glow green when these options are active. The Heat Hub should be screwed to the wall next to your boiler. The square smart thermostat has a two-inch screen that shows the current temperature of the room it’s in, as well as the desired temperature. It also displays the relative humidity and battery level, and features a flame icon to indicate if the heating is switched on. They also have the added benefit of a built-in signal range extender, automatically boosting the signal of all nearby Drayton Wiser devices. Our Verdict: We also found it was easy to create some basic automations in the app using the Moments feature - such as turning the radiators in the lounge on, while also dimming the map connected to the Wiser smart plug to create a cozy atmosphere of an evening. App From the home screen, you can also view the weather for your location and sunrise and sunset times, too. The cog icon at the top of the home screen provides access to the main Settings menu, from where you can activate smart modes such as Eco and Comfort, and set a temperature for the Away mode.

When the plug is off, the on/off button will be light grey and the smart plug will not provide power to the electrical appliance connected to it. However, it does have an Away Mode. Rather than switching the heating off completely while you’re out, this feature allows you to set a minimum temperature at which you want your home to remain at while away. If the temperature plunges below this threshold, the heating will spring to life – handy, if you're concerned about frozen pipes when you’re not at home. They might look like an ordinary adaptor or extension lead, but they can do so much more, connecting to your wifi and letting you manage your gadgets from an app on your phone. These smart radiator thermostats replace the TRVs (thermostatic radiator valves) on your radiator, the type that let you adjust the temperature of the radiator manually. If you don’t have TRVs then you’ll need to bear the cost of changing your current valves to TRVs on top of the cost of the smart heating system. There’s no denying the radiator thermostats are bulkier than TRVs, but we found we didn’t notice them as much as we expected to.The Wiser smart plugs offer the ultimate smart home convenience; when you are away from home, you can still control what goes on within your own four walls from a completely different location. They also work with your Alexa products.
