Zigbee2mqtt error encontered

Configuration Zigbee
1

Hi all,

I had Z2M installed & running without any problems for months. Suddenly since 2 days it gave errors & does not connect anymore.

I get following error

error: zh:ezsp:ezsp: Connection attempt 4 error: Error: Error: No such file or directory, cannot open /dev/ttyUSB0

The coordinator was connected to ttyUSB0. But now when I goto All hardware, I could not see any tty… there anymore.

Following are my configuration.

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:
  server: mqtt://core-mosquitto:1883
  user: mqtt
  password: mqtt
serial:
  port: /dev/ttyUSB0
  adapter: ezsp

I have installed HA in Raspberry Pi 4 & I have tried changing the USB ports but no luck by doing it.

This is my dongle.

Open Advanced SSH and Web terminal (or the other SSH add-on) and enter

ls /dev/serial/by-id

What is returned ?

Seems your Pi does not recognise the ZB-GW04 any more. Maybe try re-flashing it.

Thank you very much. Re-flashing has done the trick.
