Not sure about this but it seems as if the MQTT settings differs between your configuration.yaml and user_config.h?

The HASS uses an MQTT server called domus1 on port 1883 and the sonoff uses m20.cloudmqtt.com on port 20123, i.e. two totally different MQTT servers. Right?

Perhaps this is of some use??

Have a look at my config:

- platform: mqtt
  name: "kitchen_tv"
  state_topic: "stat/kitchen_tv/POWER"
  command_topic: "cmnd/kitchen_tv/power"
  payload_on: "ON"
  payload_off: "OFF"
5

i think the mqtt run in “domus1”

can you gei me the mqtt config?

thank you,let me see

mqtt:
  broker:    !secret mqtt_address
  port:      !secret mqtt_port
  client_id: !secret mqtt_clientid
  username:  !secret mqtt_user
  password:  !secret mqtt_password

:joy:thanks
but i can’no use you config

Have you checked to make sure that MQTT is working properly, separate from the Sonoff?

For my install, from shell, I can subscribe with

mosquitto_sub -d -u username -P password -t dev/test

then open another shell session and publish

mosquitto_pub -d -u username -P password -t dev/test -m "Hello world"

thanks! I know the question,the MQTT ip error,has been modified.
