@Grubstake Hello! I thank you to this tip.
I already have a broker MQTT to many other tasks and I'm trying to collect data to automatically decisions. I would like to have the data so simple as possible and I thinking that MQTT would be like a bridge to my own interaction. I can see already data incoming in my MQTT broker, but it's no so clear as I want. In true, the only thing that i want is the mesh network and data sending as a string json or something like that - for this reason I choose MQTT, but MySensors has a protocol behind and nor MQTT messages are clear to me.
I will think a bit more about what I can do, but if you have some suggestion to only use mesh without other layers, please, let me know.
