Zigbee network not working (Zigbee2MQTT and SMLIGHT SLZB-06)

Hi,

I set up a zigbee2MQTT Addon with brand new SMLIGHT SLZB-06 coordinator (connect with POE ethernet). This 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:
  server: mqtt://core-mosquitto:1883
  base_topic: zigbee2mqtt
  user: *********
  password: **********
serial:
  port: tcp://xxx.xxx.xxx.xxx:6638
  baudrate: 115200
  disable_led: false
advanced:
  transmit_power: 20

It starts fine. I added 2 Tuya plug, It’s works fine too. The Map show the devices as well. I can control this plugs from HA…than after an half hour, the devices goes offline, and coordinator too. I try get map, but I get this errors:

Failed to execute LQI for 'Coordinator'

Failed to execute LQI for 'Tuya Plug1'

Failed to execute LQI for 'Tuya Plug2'

The SMLIGHT SLZB-06 web interface works fine, so It’s available.

After that, I can only restart the zigbee network by going to Tools/zigbee restart on the SMLIGHT SLZB-06 website and then restarting zigbee2mqtt addon on HA. And it’s starts and works fine for half an hour. And than the zigbee network offline again.

My HA version 2023.01.07 and my system Debian11 on the Hyper-V host.

(Before I try the zigbee2MQTT with Xiaomi Gateway 3 with AlexxIT integration, but the result was the same.)

I try delete the zigbee2mqtt addon, and the zigbe2MQTT addon folder too, but it did not improve.

Does anyone have any idea what the problem could be? Is my configuration wrong?

Hi,

The problem is solved. I turned off the old zigbee network (3 pcs Xiaomi gateway3), and the SLZB-06 zigbee network works fine.

I moved all the zigbee devices to it. It has been working for 2 days without any errors.
