I’ll post a demo of the code I have written in the next few days, but I’ve got an esp32 reading temperature data and posting to a relay. I wrote a basic client that can pull in temp data and filter based on time. It’s on GitHub at
I'm curious what problem this is attempting to solve that isn't solved with MQTT and Sparkplug B protocol. Is it just a proof of concept to send data via relay? Again, you can bridge MQTT servers to replicate this. Just curious if I'm missing the point.
