Serial 2 MQTT Gateway
I have a moteino. This MCU has no WIFI. I want to forward all messages as the arrive in the moteino and forward thenm 1:1 to a MQTT broker (like mosquitto). And from there I will consume and process the messages with node-red and fhem/openhab in parallel.
This allows me to change the controller layer easily since the all support MQTT.
I remember there was already something about serial to mqtt in the forum. Did you check the search?
@siouxme if you connect the moteino as serial gateway to the system running node-red, only a few blocks are required to go from serial to mqtt (or node-red, whatever suits you best)
