Domoticz, MQTT and Sonoff basic with Tasmota: help Topic is solved

[MichelFrance]

Hello,
I am running: Domoticz Version: 2022.1 on an ubuntu server and Sonoff Basic R1 and R2 with Tasmota 11.1.0.
The server also runs a MQTT server (mosquitto) and Zigbee2MQTT.

In Domoticz I created a new hardware "MQTT Auto Discovery Client Gateway with LAN interface" with Auto Discovery Prefix = homeassistant and the Zigbee devices are well recognized and are working.

But the Sonoff devices are not recognized.

Nothing in Domoticz log, but spying MQTT, I discovered that the Tasmota-Sonoff starts with this message:

Code: Select all

tasmota/discovery/B4E62D24ED35/config {"ip":"192.168.1	...

So, I created a new hardware "MQTT Auto Discovery Client Gateway with LAN interface" with Auto Discovery Prefix = tasmota

Still no Sonoff detected in Domoticz, but now some messages in the log:

Code: Select all

What is going bad? Someone to help me? Link to a good tutorial to interface Sonoff basic/tasmota to Domoticz?
Any suggestion?

Thanks in advance

Answer to myself:
it works with "MQTT Client Gateway with LAN interface" and a dummy switch with od configured in Tasmota.

I'd like to have it work with auto discovery if possible, so this topic is not full closed. Any idea?

[waltervl]

Did you use Tasmota
SetOption19 1
To set tasmota device to MQTT Autodiscover protocol?

Thank you!

[waltervl]

Thank you!

You are welcome I suppose you got it working now?

[MichelFrance]

Yes!
