Tado radiator valves actuating when off??
I have two Tado radiator valves in a bedroom. They are set to OFF overnight, coming on at 0630 to warm the room for getting out of bed. They don't control the boiler, they are only a component of a bigger system (actually controlled for 10 years by Elv/Conrad soft zones, now unobtainable, plus a homebrew ESP32-based weather compensator).
At around 4:30 in the morning (+/- half an hour, not always the same time) I notice the valve motors actuating. They are quiet so don't wake me but I sometimes am already awake. But they are set to OFF so they have no business doing anything.
Why do they do this and how do I stop this waste of battery life?
