Homematic Integration Wall Thermostat

Dear HA Community,

I’m struggling with the this Homematic Integration. First is to set that I‘m a newbie while using HA.

Since 4 Years I’ve more then 100 Homematic actors in my house. Therefor I’ve collected a lot of experience with Homematic.

In my house I’m using Homematic (non Homematic IP) wall thermostats. This are added to a clime group where also my window binary sensors and all thermostats are.
Now I’ve already successfully add all my Homematic actors to HA. Currently I‘m struggle with the wall Thermostats. When modifying the mode or temperature the group and the wall thermostats will be modified but the heating thermostat takes longer. This can be check while I’ve running Pocket Control on my iPhone.

Does any one of you has a similar setup and observed similar issues?

Thanks in advance
