Status change and MQTT publication

Configuration
1

Hello, I am new to HA.
I would like to retrieve the change of state of my Thermostat entity and published it on MQTT.
How can I do ?

2

Create an automation that triggers on the state of your thermostat and call the MQTT service that publishes it to the topic of your choice.

Plenty of existing samples on the forum.
What piece of the puzzle evades you?

Replace {{ states(“select.blitzwolf_frigo_power_outage_memory”) }} with the correct entity_id

My id is climate.chambre_parents

But the Fan ID how to find it?

10

It is the attribute fan_mode

You will need

{{ state_attr("climate.chambre_parents", "fan_mode") }}

The system has successfully updated the file automations.yaml but without the part
{{ state_attr("climate.chambre_parents", "fan_mode") }}

I would now like to publish all the states of my air conditioning at once

current_temperature: 23
temperature: 22
fan_mode: quiet
hvac_action: heating
swing_mode: off

friendly_name: Climatisation Chambre Parents

Can I combine all this information in the same Topic Mqtt?

To be useable for the receiver, you should send json in the payload when combining several messages.

However,
