I have SLZB-06 via IP.
Below is my 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
  options: "-d -d"
  log: false
mqtt:
  base_topic: zigbee2mqtt_lan
serial:
  port: tcp://192.168.91.204:6638
  baudrate: 115200

Can anyone help?

Did you restart your SLZB-06 ?

Yes, I restarted several times and nothing works.

The only thing I can think of is to reflash the firmware

OK, I’ll try it tonight

unfortunately it didn’t help,

Same problem, reflashing didn’t help.

I have the exact same issue now with the SLZB-06. Anyone get this resolved?

Dear future Googler,

The fix for me was to delete (or rename, if you are paranoid) the /config/zigbee2mqtt/coordinator_backup.json file, and restart zigbee2mqtt
