@Kulisak Out of curiosity, but why did you set the scheduled period to till 5:59AM and not 6:00AM as well? This would prevent the one minute of Frost Protection. My KE110 installments now also work...

FYI: I'm in contact with a higher up support level and we've been testing different firmware for the past two weeks, so they're working on it

@Wayne-TP got the mail, thank you

And another missed temperature change on KE110 number 1. This is clearly a bug.

The scheduled change from 23° to 20° didn't happen tonight with my second KE110 and the heating kept running for more than one hour until I noticed. I'm sorry @Wayne-TP but that can't be the desired...

@Wayne-TP I can try that, but shouldn't the displayed "target temperature" at least match the one in the schedule? It always does so with every single TRV that is not bound to a KE110.
