HmIP-eTRV-C malfunction

Beitrag von mats@intnu.se » 12.11.2021, 11:16

Hi,
During the last months i have got the below error on 2 different HmIP-eTRV-C, once on each.

The HmIP-eTRV-C reports that the valve is open x% but it is closed, the radiator is coled.
If I try the boost function the HmIP-eTRV-C reports 80% open but the valve is still closed.

Solution is to remove the batteries for some time and then add them back and close the lid. After that the HmIP-eTRV-C has syncronized everything works again.

Anybody having any clue why this happens.

My setup is as follows.
CCU Firmware is: 3.59.6
HmIP-eTRV-C firmvare is: 1.2.4
HmIP-WTH-2 firmware is: 2.6.0

Is this the latest firmwares for the devices?
If not where can I get the latest?

PS. I just saw new CCU firmware in the GUI: 3.61.5, should I upgrade?

Thanks in advance :)
