I have Tado in 4 rooms with underfloor heating in the Minergie area, where the heating is super portable. Whether this results in energy savings, I only believe to a limited extent. The main advantage, however, is the time-based control (I only need certain rooms at weekends), the remote control (switching on and off during holidays) and the statistics. Gimmicks such as location-dependent control is of course nonsense again for underfloor heating. But all in all, I would buy Tado again and recommend it.
