Help with connecting a Sonoff/Tasmota DIY, please

Configuration
1

Hello,

I have a mini Sonoff DIY and want to add it to Home Assistant.
I did the following:

  • Flashed it with Tasmota 8.2. (I can access its web page for configuration etc.)
  • Followed the instructions with the Mosquitto broker from the add-on store, adding it and a user which I entered into the Sonoff. (The log says it has connected to the Sonoff, giving IP address and client name.)
  • The MQTT integration appeared and I added that.

This all seems to be fine, but I don’t see the Sonoff device in the Devices or Entities list.

Is there something I’m missing?

Thanks in advance!

Karl

SetOption19 in the Tasmota device will enable discovery for home assistant to automatically find it.

Or you can manually add the mqtt entities to home assistant using yaml. There’s a page about it in the Tasmota wiki somewhere.

Probably in this page: https://tasmota.github.io/docs/Home-Assistant/ - doh!

HA responded almost immediately after setting SetOption19 to 1 in the device’s console.
(Also had to set GPIO4 to Switch1 and GPIO12 to Relay1 for the mini).

Now, I can toggle a radio button in Home Assistant and watch text on a web page served from the Sonoff change between “OFF” and “ON”. Endless fun!

Thank you tom_I, you are helpful and brilliant!
