Hello.
I want to publish mqtt messages in a broker that is not managed by HA. I’ve been reading the HA documentation regarding MQTT and I can’t understand how to link the value of an entity for example → entity ID: sensor.salon_heating (which is part of an integration related to heating management) with the actual publication in configuration.yaml of the mqtt section:
If you have at hand any example, I would appreciate it.
Thanks in advance
Cheers
