HomeMatic Integration thermostat Temp-Offset

Hello!

i am using CCU3 with HmIP-etrv-2 heating thermostat. not all options are available within the HomeMatic climate serice, but some are accessable via templates, but not all. I need the temperature-offset. iOBroker has all the values available - is there a possibility to get these values in HA?

now i can only get the following ones:
