I am a bit desperate and hope someone can help me here.
I have deconz / phoscon running on a raspi 4 with iobroker. A few days ago all my zigbee devices suddenly stopped working. I tried restarts, loaded a backup via phoscon, than I tried to load some older zigbee configs ( Network lost issues · dresden-elektronik/deconz-rest-plugin Wiki · GitHub ) but nothing fixed the issue. No connection to any device could be established.
I tried a fresh installation of Raspberry OS and deconz and used the gateway backup but that did not help either. I reseted a lamp and tried to reconnect it but i had no success in doing so.
Also using a backup image of the whole system from when I new it was working had not positive effect.
So I thought that possibly the stick was broken and I ordered a new one. With the new Stick and restored zigbee configuration it worked again for about 5 Minutes. After I tried to reconnect the lamp that I had previously reset, the connection to all devices failed again and now I’m back at the same point.
Has anyone an idea on what i can do next or what the problem might be? The setup worked pretty stable perviously.
