This repository contains a Grafana dashboard for rtl_433_prometheus. This script exports a various data captured by rtl_433, which is another awesome script for decoding unlicensed 433MHz ISM band. This band is mainly used by low power RF devices, such as simple temperature, humidity and other sensors, and even by cars (TPMS). Using my dashboard (both Slovak and English version), you can nicely see temperature and humidity data.

When it comes to hardware, basically any SDR receiver will do. On the other hand, the most important thing is an antenna, mainly the placement. I am using RTL-SDR Blog V3 with 4 elements Yagi-Uda antenna for DAB radio. The antenna is absolutely not tuned to 433MHz, but it works well, as it is mounted on my roof.
