Use MQTT retained value as condition?

Configuration

Hey,
Google wasn’t too helpful, so here’s my question for all of you lovely folks.
As far as I see it right now it is not possible in an automation condition to ask for an MQTT state, something along the lines of (and I’m completely making this up)

condition:
  - condition: template
    value_template: '{{ mqtt("my/topic") > 0 }}'

Am I correct in that assumption? I would guess I’d have to incorporate an input_number into that automation?

Best regards and happy new year
Halest

Create an MQTT sensor. Sensor subscribes to the topic on MQTT, and your automations work off the sensors state

Ah, so that’s what the other Google results meant. I thought they were talking about actual physical sensors.
Thanks, I’ll try that out

Yeah. An MQTT sensor/switch/binary sensor is nothing more than a “fake” device subscribing/publishing on topics.
