How to turn a mqtt.publish assignment into a light switch in lovelace?

Configuration Frontend

Hi I’m a new user of Home Assistant and have been reading forums for weeks now to set up a good system myself.

This works quite well, but I still have one problem with sending a message via a light switch in Lovelace via mqtt.publish to my Sonoff 433Mhz RF Bridge.

With this command in Developer Tools I can switch it on and off. So that works.

Lights ON

topic: “cmnd/tasmota_C2350D/RfRaw”
payload: ‘AAB04E050801540A3200BE04D827EC01020302030203030202030203020302030203030202030302020302030302020303020203030202030203020303020203030203020203030202030203020302030455’

Lights OFF

But how to proceed? I completely lost it.

Thank you in advance for your help!

Why not create a template switch which you can then put in your Lovelace

switch:
  - platform: template
    switches:
      light_name:
        turn_on:
          service: mqtt.publish
          data:
            topic: “cmnd/tasmota_C2350D/RfRaw”
            payload: ‘AAB04E050801540A3200BE04D827EC01020302030203030202030203020302030203030202030302020302030302020303020203030202030203020303020203030203020203030202030203020302030455’
        turn_off:
          service: mqtt.publish
          data:
            topic: “cmnd/tasmota_C2350D/RfRaw”
            payload: ‘AAB04C0408012C0A6404F6283201000200020002020000020002000200020002020000020200000200020200000202000002020000020002000202000002020002000002000200020002000200020355’

First of all, thank you for your quick help.

I put it in my configuration.yaml, but I get this error.

Error loading /config/configuration.yaml: ‘utf-8’ codec can’t decode byte 0x93 in position 461: invalid start byte

That wouldn’t be anything to do with that switch template. Take a look here:

The configuration files, including configuration.yaml must be UTF-8 encoded. If you see error like 'utf-8' codec can't decode byte , edit the offending configuration and re-save it as UTF-8

With troubleshooting the config has been restored.

Sorry apmillen I could not make the switch with your setting for configuration.yaml.

Then i get the message: Entity not available: switch.mqtt_switch

The setup of @apmillen is basicly correct, however, never use ‘fancy’ quotes :

switch:
  - platform: template
    switches:
      your_light_name:
        turn_on:
          service: mqtt.publish
          data:
            topic: 'cmnd/tasmota_C2350D/RfRaw'
            payload: 'AAB04E050801540A3200BE04D827EC01020302030203030202030203020302030203030202030302020302030302020303020203030202030203020303020203030203020203030202030203020302030455'
        turn_off:
          service: mqtt.publish
          data:
            topic: 'cmnd/tasmota_C2350D/RfRaw'
            payload: 'AAB04C0408012C0A6404F6283201000200020002020000020002000200020002020000020200000200020200000202000002020000020002000202000002020002000002000200020002000200020355'

and of course you can only have one switch: statement

Ahh I missed those damn fancy quotes! Thanks for rectifying!

Thank you all for your help. With this config I indeed have a working light switch in my lovelace interface.

It can control my Sonoff RF Bridge Portically via the MQTT. On and off works, only now the question if I can put multiple switches in it and if I can create automations for these switches.

Configure a default setup of Home Assistant (frontend, api, etc)

default_config:

Text to speech

tts:

  • platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
sensor: !include sensor.yaml

switch:

  • platform: template
    switches:
    light_name:
    turn_on:
    service: mqtt.publish
    data:
    topic: “cmnd/tasmota_C2350D/RfRaw”
    payload: ‘AA B0 4E 05 08 0154 0A32 00BE 04CE 27EC 010203020302030302020302030203020302030302020303020203020303020203030202030302020302030203030202030302030202030302020302030203020304 55’
    turn_off:
    service: mqtt.publish
    data:
