Several weeks ago I integrated this device: Zigbee Steckerleiste
Worked quite well for a while then it was not available one day. A few days later it was available again. Nothing was done in the meantime. No it’s again marked as not available since several days, trying to reconnect and restarting the raspberry which is running HA didn’t help.
What else could I try?
Removeing it and reintegrating it every few weeks is no useful option.
Basic troubleshooting tips here:

What is it connected to … stick or zigbee(mesh) router object? Check the signal strength and.a tip: when you pair it with the stick/hub… you should do that from the location where you use it. example: pairing next to the stick and then move it to another floor might work but it might also not have the best/efficient connection
Sorry for the long delay,
I had to wait until the problem occurred again.
I checked all troubleshooting tips, none of them was relateed to my problem.
It’s connected directly to my zigbee usb stick (sonoff zigbee usb 3.0 donlge) and less than 1 m apart, both on my desk.
In the log there are a lot of error messages (I have no idea what is cauing them or what they could mean):

Looks for me as if the zugbee stick is not woirking, though there is no error shown in HA (but all entities are not available - I don’t hae currently other zigbee entities).
