The Bosch Radiator Thermostat II is the upgraded version of the original - and will also be available with Matter from the end of 2024. It has a robust housing, a large, easy-to-read display and a nice light ring that briefly lights up red or blue depending on the set temperature. The smartphone app could do with a bit more love: it seems confusing - important functions are hidden in the menus.

On the road and forgot to turn off the heating? With digital radiator thermostats, that's no longer a problem. The room temperature can be turned up or down from anywhere via a smartphone app. The apps also enable automatic heating according to schedule. At home, heating only takes place when it should be warm - without you having to worry about it. This way you can also save energy and costs.
