Embeded MQTT, switch unavailable

Configuration
1

Hi All,

Could i get some advice, I’m new to HA, have just setup MQTT (embeded) and my switch is marked as unavailable (using a flashed sonnof tasmota).

my configuration.yaml;

mqtt:

switch:
- platform: mqtt
  name: "Immersion Heater"
  state_topic: "stat/sonoff_immersion/POWER"
  command_topic: "cmnd/sonoff_immersion/POWER"
  availability_topic: "tele/sonoff/LWT"
  qos: 1
  payload_on: "ON"
  payload_off: "OFF"
  payload_available: "Online"
  payload_not_available: "Offline"
  retain: true

my Tasmota settings:
Host: 192.168.0.66
Port: 1883
Client: sonoff_immersion
Username: homeassistant
Password:
Topic: sonoff_immersion
Full Topic: %prefix%/%topic%/

I don’t get any errors in the dev-info, and i can get to my sonoff switching using its native http access and toggling it works.

I think your availablility topic is wrong.

your availability topic is most likely “tele/sonoff_immersion/LWT” and not “tele/sonoff/LWT”
