Homeassistant discovery zigbee2mqtt bulbs state channel missing

Hello,

homeassistant auto discevory works good for me (openhab 5.1.1) with zigbee2mqtt. But all my bulbs from zigbee2mqtt are missing the state channel. For example my “Bad” Group. When i add the auto discovered group as a thing in openhab the state channel is not discovered:

The same problem occures with bulbs that are not in a group. I am unsure where to look for the problem. Is it a zigbee2mqtt problem or the openhab addon? It would be great if someone could give me a little advice where to look for the origin of the problem. Thanks a lot!

The problem was me. I am using openhab since more then 10 years. At the moment im am starting from scratch with proper semantic modeling etc. So if someone else ist landing on this thread. The behaviour is intended. Because you can use a brightess or a color item like a switch. It is all documented. I just did not find it:
