Store value from mqtt event and only trigger if it changes

Configuration
1

Hi, This automation triggers each time the shelly switch is pressed, via mqtt
The problem is, it also polls every 30 seconds so it triggers each 30 seconds as well

alias: shelly_test
description: ""
trigger:
  - platform: mqtt
    topic: shellies/shelly1l-E8DB84AB4E5D/input/0
condition:
  - condition: template
    value_template: "{{trigger.payload != input_number.current_shelly_switch_input}}"
action:
  - type: toggle
    device_id: b8ec72d8f44c0beca6bcfda68dbd0c57
    entity_id: light.luz_armario
    domain: light
  - service: input_number.set_value
    data:
      value: "{{trigger.payload}}"
    target:
      entity_id: input_number.current_shelly_switch_input
mode: single

I’m not sure if the condition works, and I’m not sure if I’m saving the payload value correctly in the input_number helper I created.

The payload it self is either a 0 or a 1

Hmm, i would approach it differently…

Create a sensor from mqtt (which subscribes to the topic)

And then use that sensor change to trigger your automation :wink:
