Hi klakol!
starting from your very hepful work i managed to get infos in HA from my De Dietrich Alezio heat pump.
Now i have some troubles with DHW tank temperature…do you had any luck with this regisrer value? I got always or 0 or invalid value. Just tried all device_class (int16, uint16, float16, etc…). or maybe do you found this information (DHW tank temperature) from other register…
solved reading the equivalent register in Zone 2 so 1631 and 1632.
