The Aqara W600 radiator thermostat lets you control your heating with your phone, without the need for a complex or pricey installation process. Instead, this plug-and-play (almost) smart radiator valve gives you instant remote control of a dedicated radiator in your home.
Buy a bunch of them, and you can fit them to many of the radiators in your home, providing room-by-room control over the temperatures in each.
