Hi evebody.
I’m trying to get the value of temperature from ispindel using Mqtt and if this value is around 19 Celsius, trigger a heater in fermentation place to increase the temperature to 20/21 Celsius.
I tried this without success
trigger: mqtt
topic: ispindel/iBigode01/temperature
payload: "{{ 'temperature:' > 20 }}"
encoding: utf-8
action: switch.turn_on
target:
device_id: 5c87152c0f0d783774d827a6b9b0d870
data: {}
Manually works..
Any help will be appreciated.

You cannot use a template in the trigger like that to make a decision. You can only extract the value in the trigger and then use a condition to check if it's what you want

I would first create an MQTT sensor for the temperature. Then you can create any number of automation based on the state of that sensor. You also will get history data for the temperature should that be useful.

@final ridge thanks. I can’t predict the exact value of temperature. Each one could have x.99 values and this sensor sends messages every 15 minutes.
@wraith sentinel Thanks.
The sensor already created.

That doesn't matter. You trigger on any change to the topic and use a condition to filter what you want

Could you give me an example ?

Here's a post from a guy trying to do exactly what you were trying to do: https://community.home-assistant.io/t/conditional-trigger-on-mqtt-payload/350116

Thanks, @final ridge I managed how to do it, and now it is working like a charm 🙂
