Problem with Homematic(IP) updates

Hello. I am using a Homematic CCU3 and Openhab 2.4, running on a Synology.
Now i have a problem and i can’t fix it.

Every (Homematic)Switch is not updating on the Openhab-Item (for example, i turn on the light in the kitchen with a homematic hardware-button Openhab gets no update).
There is only an update, when a HomematicIP Component is switched on.
So -
Homematic Component: No update (no update on Sitemap or Habpanel)
HomematicIP Component: Update.
I can’t find any entry in the logfile to fix this problem.

Thanks for help

Solved. I removed all non working HM-Components from OH and connected them new. Now it works…
