LoRa mesh on the bench

I’ve been building and testing a LoRa mesh setup, with an interactive dashboard to see what the sensors are doing.

In these tests, I’m watching the radios hop between frequencies in SDR++ on the left, while my dashboard on the right shows button state and liquid level. It’s useful to see the radio activity and sensor updates side by side.

Button-state test, with SDR++ and the dashboard side by side. Still from my test video.

Liquid-level view in the same setup. Still from my test video.

Still a work in progress. For now, I’m putting the pieces together and checking how they behave on the bench.
