ZHA + Conbee2 no setup possible

I‘m trying to add my Conbee2 Stick to HA via ZHA. HA is running in a docker-compose in privileged mode on a Ubuntu Server. I’ve not mentioned the ttyUSB in my config as it seems not necessary. Any ideas?

Unfortunately I always get these errors:

The above exception was the direct cause of the following exception:

Config entry 'ConBee II - /dev/ttyACM0, s/n:xxx - dresden elektronik ingenieurtechnik GmbH - xxx' for zha integration not ready yet; Retrying in background

Looks like the conbeeII is not ready/answering. Do you have Dezonz add-on or integration installed? It should not be installed if using ZHA

I had deconz running in a separate container, but removed it

Make sure:

  1. That you don’t have modem manager installed
  2. That the ConBee is on a short (0.5m to 2m) USB extension cable, and well away from any computers/WiFi devices

I’ve disabled ModemManager but still the same error…

Connected it USB3 no more troubles… ok why not
