Hello,
I have a problem getting my heating to work in Home Assistant.
It works perfectly with the glass button from MDT.
In the HA I only get the temperature displayed, but I can’t adjust the temperature.
So that it can be seen on the glass button that the target temperature has changed.
Here is my config maybe someone of you can give me a tip.
I am very glad for any help.
Hi 
!
Your setpoint_shift_address is 4/0/20 and it’s state_address is 4/0/23
And you don’t seem to have a GO for operation_mode_state_address - maybe you can activate it in parameters or use the same address as for setting (and eventually set the read flag).
PS. Your post will eventually be deleted by mods since it is not written in English. See How to help us help you - or How to ask a good question
I’m so stupid 
This was the solution. Big thank you
