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 Radiator Thermostat 2 Units is a good set to control your radiators individually. Install the Tado app on your smartphone and tablet, and set the temperature per radiator. Make sure you have the Tado bridge. Without the bridge, you can't control the radiator thermostat via the app. You can set the desired temperature per room. That means no more cold bathrooms. Since the radiator thermostat and your smartphone or tablet are connected at all times, the temperature automatically drops when you leave the house. You'll never have to think about turning off the heating again.
