The cold bathroom in the morning is just as uncomfortable as the turned on radiator with the window open. With smart radiator thermostats you can prevent both – and ideally also save money. Because the thermostats control themselves with sensors and rules that have to be created once. Spontaneous interventions – whether directly on the device, via voice or app – are still possible.
After our comparison of twelve smart thermostats in October 2020, we wanted to know which functions current models will offer in autumn 2021, how great the gain in convenience will be and how quickly they will pay for themselves. We changed three models compared to the previous year: The Livisi thermostat is no longer available, updates announced by Fibaro are missing and the third generation Eve Thermo is no longer up-to-date. Bosch, Meross and Homematic IP are also involved with a new, second thermostat. Once again represented are AVM, Eurotronic, Gigaset, Netatmo, Revolt, Tado, Telekom and Wiser – which complete the mix of budget and premium models.
The installation on the radiator is relatively easy everywhere: Loosen the old thermostat, tighten the new one. Sometimes you need a pipe wrench, but mostly manual use is sufficient. Almost all devices fit the valve directly. If this is not the case, the adapters, which are often included in the scope of delivery, will help. With Netatmo you have to use one.
