Hi,
After upgrading HA to 2025.10, I noticed that Z2M is not starting up. When looked into the addon log, this is the error I see:

error: z2m: Error: failed to start adapter connection to firmware at Timeout.<anonymous> (/app/node_modules/.pnpm/zigbee-herdsman@6.1.5/node_modules/zigbee-herdsman/src/adapter/deconz/adapter/deconzAdapter.ts:116:28) at listOnTimeout (node:internal/timers:588:17) at processTimers (node:internal/timers:523:7)

It was working properly and nothing has been changed since then, except HA upgraded to 2025.10.
Im running HAOS on proxmox. Z2m addon version is '2.6.2-1'.
Any help would be appreciated!
Thanks!

A HA upgrade shouldn't affect the Z2M addon. Please share the whole log as well as your config.

Have you already rebooted your vm? Recommend reboot vs. restart after updating os

restarting the Proxmox fixed the issue! Thanks!

I'd still like to see that config. Maybe you didn't use a proper reliable path.

distant raptor I'd still like to see that config. Maybe you didn't use a proper reliable path.

is this one you're referring to:

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
  options: "-d -d"
  log: false
mqtt: {}
serial:
  port: /dev/ttyACM0
  adapter: deconz

Yes. Deconz might be specific here but generally you'd want to use a /dev/serial/by-id/... path. See what this says

ls -l /dev/serial/by-id/

➜  ~ ls -l /dev/serial/by-id/
total 0

#

Great. Use that instead.

grim breach Oct 8, 2025, 5:21 AM

#

ran ls command inside HAOS terminal

#

sorry use what instead? and whre in config? (sorry but thanks!)

light wagon Oct 8, 2025, 5:24 AM

#

in your zigbee config where you set the /dev/tty path. replace /dev/ttyACM0 with the id

grim breach Oct 8, 2025, 5:25 AM

#

so should be:

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
  options: "-d -d"
  log: false
mqtt: {}
serial:
  port: usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2686332-if00
  adapter: deconz

?

distant raptor Oct 8, 2025, 5:25 AM

#

Replace

/dev/ttyACM0

with

/dev/serial/by-id/usb-dresden_elektronik_ingenieurtechnik_GmbH_ConBee_II_DE2686332-if00

That way it will always point to the right device even if you add another serial device.

ah ok. let me fix it!
