Ha! Today has been a good day. I’ve got my Air Quality sensor talking MQTT to the Connected Humber server and sending messages. This has been a bit of an adventure, mainly because I had to mess around with the libraries for the Heltec device that I’m using.
Anyhoo, I’m now sending messages over both LoRa and MQTT at the same time. Go me. Now I just need to add some configuration options and I think we might actually have a product here.
Incidentally, I’m using a Windows app called MQTTBox to view the messages on the server and post test messages to my sensor. Works rather nicely. And free.
