Description

The TRV always switches back to system_mode "auto", which means that schedules of the TVR will be used and not BT. This "fall-back" happens with certainty when a window is opened and closed again, and the window contact switches the system_mode to "off" and then back to "heat". But the fault not even happens by manual triggering (window), but also automatically at irregular intervals. It seems like the default logic of the TRV checks the current_heating_setpoint in certain intervals, and sets it back to its own schedule temperature.

In this z2m-issue (#4750) the problem is described, with the advance to correct the problem in the automation of the respective task. I guess this need to be done in the BT-automation?

Steps to Reproduce

1. Set desired temperature in BT
2. Wait some time - or open and close a Window (manual trigger)
3. TRV switches to system_mode "auto"
4. The temperature and the settings of BT are no longer taken into account from the TRV: system_mode "auto"

Did you check the config: "If the auto means heat for your TRV and you want to swap it" if its checked, uncheck it

[Daniel-WW]

Hi, yes, this is unchecked.

Same for me, same TRV, same behaviour. Havent looked into it, but I guess BT is using Manual mode. You probably can set manual mode again after the TRV was set back to system_mode "heat" via attribute "preset". When I fiddled arount with it, it seems there needs to be a delay between setting "system_mode" and then "preset".

I have the same issue, BT is unusable for me. Would be nice to actually have a mode where BT just changes temperaturs, and leaves the modes alone. Off = set temp to 6° for example.

There is an option for use min temp in beta 51 now
