Z2M onbording screen

Configuration Zigbee

I know that there have been similar threads, but unfortunately I haven’t found a solution to my problem. I have a SONOFF MAX dongle. I’ve tried various configurations, but for some reason the panel won’t show up.

Config:

version: 4
mqtt:
  base_topic: zigbee2mqtt
  server: mqtt://core-mosquitto:1883
  user: xxxxxx
  password: xxxxx
serial:
  port: >-

  adapter: ember
  rtscts: false

  ext_pan_id: GENERATE
frontend:
  enabled: true
  port: 8099
homeassistant:

And log from Z2M:

ZHA is not integrated, rtscts: false, configuration as shown above. I have no idea what is wrong.

Set onboarding to false

9

no change after that

10

Could the fact that the HA is supervised cause this problem? I don’t think it should have any effect, but I’m looking for a starting point.

Problem solved - I added “#” before
Onboarding page is available at http://0.0.0.0:8099/
and it works
