No control after Raspi Reboot

Hi there,
I’m new to deCONZ. I successfully installed the image on a Raspi 4 and added 2 Paulmann light controllers (one LED stripe and one Dimm controller).
I can control the dimm level an on the stripe the colour temperature.

Now the problem: After rebooting the Raspi, there is no more control on the items. The also flash red in the deCONZ App.
What should I do?
