Sonoff 4CH help

Hardware
1

I followed the steps from Dr.zzs - https://www.youtube.com/watch?v=NNW05smSNOA and flashed the 4CH device.

I can that the device has connected to the MQTT from the logs - 1543166045: New client connected from 192.168.1.75 as Sonoff_4CH (c1, k10, u’MQTT’).

I used the “SetOption19 1” and still the switches are not getting discovered by HA even after several restarts, please help.

TIA

Have you tried manually configuring it? I have not tried the discovery option yet.

You will want something like…

configuration.yaml

light:    #or you can use switch:

  - platform: mqtt
    name: "Channel 1"
    state_topic: "stat/sonoff4Chan/POWER1"
    command_topic: "cmnd/sonoff4Chan/POWER1"
    availability_topic: "tele/sonoff4Chan/LWT"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    payload_available: "Online"
    payload_not_available: "Offline"
    retain: false

  - platform: mqtt
    name: "Channel 2"
    state_topic: "stat/sonoff4Chan/POWER2"
    command_topic: "cmnd/sonoff4Chan/POWER2"
    availability_topic: "tele/sonoff4Chan/LWT"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    payload_available: "Online"
    payload_not_available: "Offline"
    retain: false

  - platform: mqtt
    name: "Channel 3"
    state_topic: "stat/sonoff4Chan/POWER3"
    command_topic: "cmnd/sonoff4Chan/POWER3"
    availability_topic: "tele/sonoff4Chan/LWT"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    payload_available: "Online"
    payload_not_available: "Offline"
    retain: false

  - platform: mqtt
    name: "Channel 4"
    state_topic: "stat/sonoff4Chan/POWER4"
    command_topic: "cmnd/sonoff4Chan/POWER4"
    availability_topic: "tele/sonoff4Chan/LWT"
    qos: 1
    payload_on: "ON"
    payload_off: "OFF"
    payload_available: "Online"
    payload_not_available: "Offline"
    retain: false

“sonoff4Chan” being what ever you named the device on the mqtt setup page on the Sonoff 4Ch

Apparently, I can’t post the same message in two threads, so can you do this

Adding the switches manually worked, I used the MQTT.FX tool to check the messages. I did notice that the QOS for mine was set to “0”, where do i change it to QOS1?
