New Danfoss 1.32 OTA causes issues on Popp hardware

[sopelt]

Hi @AresMaster , hi @Koenkk ,

I have several Popp TRVs which are a variation of this device/Danfoss Ally. The 1.32 OTA which was added for Danfoss was also offered as an update for the Popp devices.

After the update the valve motor is moved every 1-2 minutes (only very shorty - more like a click) which is annoying and probably a battery killer. Do the Danfoss Ally devices work as expected with this update? I tried downgrading but it seems to be rejected by the device and I get INVALID_IMAGE. I tried all variations of settings and also removed some of the reporting intervals.

As a last resort I removed a TRV from the network, factory reset it and just let it run standalone (without joining any zigbee network) and it still moves the motor every minute which looks like a clear indicator that the firmware introduced this behavior as the devices worked as expected the last two heating seasons.

I would try to avoid offering the OTA to Popp devices until there is more feedback/clarity if this is a general problem for that combination or if it is more complex.

I would appreciate any input on how to further diagnose/resolve this issue.

Thanks for all your work!
