I’ve created a (hopefully) all-in-one gateway solution for LoRaWAN on TTN. (PiWAN)
Running it on the RPi should host a Grafana dashboard that includes monitoring the health of the GW/RPi + packets being received (to your own application on TTN).
I’ve been using this setup for a couple of gateways using RPi4 + RFM301 for almost a year now (recently open-sourced the project).
Feedback (and contributions) are appreciated. I don’t have the capacity to test different boards (yet).
