I’m not sure and I think it’s similar to one of my enhancement requests: Récupérer une valeur "text" depuis MQTT
Envoyer un message MQTT only allows displaying a text on the dashboard (and that’s great!).
But in our case we want to be able to retrieve this Text value from MQTT to reuse it in scenes, for example, and in my request to retrieve a Text value from MQTT coming from another system.
