[solved] HA-OS & Conbee II (z2m): stick at /dev/ttyACM0, cannot get z2m running

I installed HAOS directly on an older Atom board that I had laying around.
Now I’m trying to get a Conbee II running with z2m

ATM I don’t know what FW is on the Conbee II and I have seen that there might be issues with z2m (depending on the FW version)
If the FW is to new, is it possible to go back to a working version?

I found the device under ‘System’ → ‘Hardware’ → /dev/ttyACM0
Used that as the port in z2m but doesn’t work.
Also added the following to (first without the port) configuration.yaml:

serial:
  adapter: deconz
  port: /dev/ttyACM0

No luck either: z2m fails to start

EDIT: this is the error I get

Error: Failed to connect to the adapter (Error: SRSP - SYS - ping after 6000ms)

According to: Error: SRSP - SYS - ping after 6000ms I guess it is related to the port but have no clue how to solve this with HAOS.

Thanks already for any help!

Try using the device by ID address - mine is - /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DExxxxxxx-xxxx

You should see it under settings - system - hardware - all hardware

Hi Simon, thanks for jumping in!
I have tried that too. Did you only use this in the z2m add-on like this:

port: /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DExxxxxxx-xxxx

Nothing in your configuration.yaml and are you also using HAOS?

Yes HAOS and nothing in configuration.yaml

BTW, the xxx’s at the end of the address are related to my specific adapter and I blanked them out.

You should find yours under settings - system - hardware - all hardware

Ok, so this is what I have now:

  1. I removed those settings form configuration.yaml
  2. configuration from zigbee2mqtt

The rest is default.

This is the way I got it working: in the Zigbee2MQTT add-on configuration, under ‘serial’

port: /dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DExxxxxxx-xxxx
adapter: deconz

Thanks a lot for your help Simon!
