Noobie needs a helping hand

Hey.
I tasmotized a IR blaster (dont ask me why! Long story!) and I can check TASMO_IP to use the console. It works! If I send this command Ill get an IR flash to turn on a gadget.
IRsend:{"Protocol":"NEC","Bits":32,"Data":"0x807F50AF","DataLSB":"0x1FE0AF5","Repeat":0}

My MQTT settings are
user: mqtt_user
password: xxxxxx
topic: tasmotair
Full topic: tasmo/%topic%/

The Tasmota Info page (http://TASMO_IP/in?)

Program Version 13.2.0(ir)

And for a first test I went to https://HASS:8123/config/mqtt
and tried every combination of my topic name and the full name… What do I have to write into “topic” to send the command to my Tasmota device.

I also tried to correct every " and turned them into "

And as I am here helpless let me add 2 more questions

How do I create a pushbutton on my dashboard which sends the command to the Tasmota device?
And how can I use this in an automation?
When I give voicecommand X

  • turn on x
  • turn off y
  • send command xyz via MQTT to “TASMO_IP”

Much appreciation for your help.
Help me keep my sanity :smiley:

For all others who struggle and find this

Publish the payload in curly brackets as payload to

cmnd/tasmtair/IRsend
Thats the MQTT Full Topic ,but the command comes into the topic string!!!

And if you want to listen to the stuff from the console:
It works for me to lusten to tele/tasmotair/# as a wildcard. This keeps a lot of sys info out of my logs, but gives me all the infos to work with. That was a lot easier to understand.

Cheers,
