Hey there,
I’ve got a weird problem, and I’m hoping this is the right sub-forum.
For three months, my TRVZB worked just fine. Lately, it’s randomly turning into ‘IN’ mode (which normally indicates it’s looking for Zigbee connections), and thus opening the valve all the way up, with no way to stop it. Only thing that helps is taking off a battery, then it quickly returns. Not so practical if I’m not at home and can watch the temperature go nuts from far away.
I’m using ZHA for the Zigbee connection, Better Thermostat to control the device. Oh, and I made sure the batteries aren’t empty.
I can’t seem to find a pattern, it just happens after running for some hours. I originally thought it must be connected to Better Thermostat, which was updated to 1.7.0 a few days ago, but even reverting to 1.6.1 and restarting HA doesn’t help. I can neither talk to the valve via the ZHA device nor through Better Thermostat. When I try to turn it off via ZHA, the interface returns something like ‘Could not turn device on/off, device not responding’, even though the device has been seen in the Zigbee device’s settings.
Is this some known issue, with TRVZBs in general, ZHA or Better Thermostat? Anyone else encountering this?
Thanks in advance!
