Yes, exactly! Actually I do not have a clue what is wrong. It has the necessary HVAC modes as well as the right mode (Manual). My question is: Why do “Homematic” devices do not react to the services to climate.turn_off (if it is on) and climate.turn_on (if it is off)? (Please double-check again before proceed!)
I have absolutely no experience with Homematic besides it is a very popular system in Germany. Therefore, please ask some Homematic users, how they are experiencing and handling Homematic Climate devices and forward the information to me.
Of curse there are several ways to control the climate. On the other hand this blueprint is aiming to be a general solution for all climate.* entitys in HomeAssistant. If there is NO other solution to it, I would recommend designing a special Blueprint just for the Homemtic users.
