Cannot use Onecta as action in automation, to set the offset

Hi everybody,

Nice to meet you all here. I am new in this forum.

I just connected my Altherma 3 using the wlan and added the onecta integration in my HA.
But I cannot use it as an action to change the leaving water temperature offset.
I can only do one of the followings:

  • change hvac mode
  • change leaving water temp preset mode to away or none
  • refresh

Can someone please help?
Thank you
