as much as I do like automation, I’m still strongly convinced that radiator valves are the most wrong things to do automation with and it’s because three main issues:
- battery
- battery
- reliability
I can kind of understand that they are working in small places (but then it does not make much sense to have one). But in quite normal bigger house with like 10-20 radiators it’s nonsense, just simply because changing battery is pain and reliability in connection is very discutable.
I would love to see some valves with tasmota and some sort of wired power tho
