Add entites too Rooms

i have configure Hometic CCU (without IP) in the Configuration.yaml.
I can configure all devices, that i will add to the Raspberymatic CCU.

How can i add the entities to the specific rooms?

I can’t see any Tab where i can move the entity to a room. WIth Devices i can do this, but i can’t see any Devices for Homematic. It’s all entites.
