This repo contains instructions and code to setup a Raspberry Pi to act as a "stats hub" for the OpenTRV/Radbot Thermostatic Radiator Valves.

These TRVs transmit a short radio burst approx. every 2 minutes, which can be picked up by RFM23 or compatible radio modules working at 868MHz. A custom Python program detects these & accumulates the 20-ish data points they transmit over a full cycle in an open-source time-series database called Prometheus. A monitoring interface called Grafana turns this into easy to read graphs of temperature, light levels or valve activity.
