The dongle and configuration is migrated from PC where it worked just fine.

Zigbee troubleshooting instructs to use udevadm to check and set write permissions by editing /etc/udev.conf which is not present in HA Green.

Getting error “udevadm: command not found”

[core-ssh ~]$ ls -1 / dev/serial/by-id
total 0
Urwxrwxrwx 1 root root 13 Jan 25 2024 usb-ITEAD_SONOFF •_Zigbee_3.0_USB_Dongle_Plus_V2_20220818080600-if00 > ../../ttyACMO

[core-ssh ~]$ test -w ../../ttyACM0 && echo success || echo fail
fail

[]$ udevadm info -a -n /dev/ttyACMO | grep 'serial'
bash: udevadm: command not found

This exact configuration and dongle worked fine on a PC.

Alternatively user can be adde to groups tty, uucp, dialout. But it seems like it’s running under root anyway? There’s no homeassistant user. And no commands like usermod.

What can I do to make it work?

Thanks!

Why don’t you use

port: /dev/serial/by-id/usb-ITEAD_SONOFF •_Zigbee_3.0_USB_Dongle_Plus_V2_20220818080600-if00

in your Zigbee2MQTT configuration, instead of /ttyACM0 ?

(ID is not correct, but I pasted it from your post)

You can see at tehend of line it shows it’s symlinked to > /dev/ttyACM0 and exactly same was working on a PC, addressign through /dev/TTYACM

And that port id is full of special symbols, I’m not sure it’s possible to input.
But I will try, thanks for suggestion.

First do

ls /dev/serial/by-id

and then copy it to Zigbee2MQTT’s configuration

Finally managed to get the id exactly right and getting same error as through symlink ttyACM0:

config:

data_path: /config/zigbee2mqtt
socat:
  enabled: false
  master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
  slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5

Ok, it is a dongle E

data_path: /config/zigbee2mqtt
socat:
  enabled: false
  master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
  slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
