Devices not answering after backup restore


I have a Conbee II connected to a Raspberry Pi 4 (headless).
Some other program on that RasPi stopped working after a try to upgrade.

I took a new SD-card and put a new openhabian 32 bit on it.
I configured the openhabian and installed deconz.
I restored the fresh backup file into the new phoscon web client.

Everything seemed to work perfectly.
I can see my groups and lights.

But they do not respond to switching them on and off.

Where is the problem and how can we debug it?
Do I have to take any additional values from the old sd-card image?
If so, is it possible to gather that information headless?
