The smart radiator thermostat from Tado doesn't work with all brands of radiator valves. Check beforehand which brand of thermostat dial you have. The radiator button from Tado is suitable for faucets from Caleffi, Comap, Danfoss, Giacomini, Herz, Olymp, Siemens, and Terrier.
The Tado Smart Thermostat V3+ Smart Thermostat including 2 Radiator Knobs can make your home more efficient. The V3+ is compatible with all smart platforms. You can also control the thermostat wherever you are with the Tado app. In the app, you can set a weekly schedule so it's always nice and warm when you come home. Because the thermostat is constantly connected to your smartphone, it knows exactly when you're near your home. This means you won't have to heat your home unnecessarily, which saves you a lot of money. The same is true for the open window detector. When the window is open, the thermostat automatically lowers the temperature by a few degrees.

For the thermostat's wired connection, connect the thermostat to the wires of your current thermostat. Are you using the thermostat wirelessly? In that case, you'll need the extension kit to fully connect the thermostat. This isn't included by default.
