Phoscon loses connection to ConBee II

Hello everyone,

I have an inexplicable problem.

The deCONZ binding with the Phoscon app on port 8090 has been running in the background on the same Raspi as openHAB 3.4.4 for some time without any real problems.
Two IKEA STARKVIND and currently 4 HUE lamps (3x extendedcolorlight, 1x colortemperaturelight) are registered.
Suddenly I can’t control my lights anymore and get no more sensor data.
In OH, a lamp is displayed online that is definitely off and all other devices are offline.
My ConBee2 stick is no longer displayed in the Phoscon app, but the Phoscon Gateway.
In addition, the details of the gateway are missing. …NOT CONNECTED…

After testing a new ConBee2 stick, another USB extension cable and all USB ports - all to no avail - I tried the following:
7 days old backup image → does not work
14 days old backup image → works !!!
All devices are active and controllable again, in Phoscon my ConBee2 is displayed again with all information…
…that was yesterday.
And today…
Again no communication with the ConBee2 stick.

I updated the firmware on the ConBee in Windows.
The Phoscon app has the following version:

openhabian@openhabian:/ $ apt list -a deconz
Auflistung… Fertig
deconz/unbekannt,now 2.21.02-debian-buster-stable arm64  [installiert]
deconz/unbekannt 2.21.02-raspbian-buster-stable armhf

I have now done the following:

sudo systemctl stop deconz-gui
sudo systemctl stop deconz
/usr/bin/deCONZ -platform minimal --dbg-aps=2 --dbg-info=2 --dbg-error=2 | tee debug.txt

The result is in this link.

Somehow an update doesn’t seem to run properly or the hardware path is wrong?!?

Is the problem visible somewhere and is help possible?

Thanks and regards


You updated your full pi by any chance?

If so, you probably are affected by this:
