Generic ISM-band receiver and decoder for 315 / 433.92 / 868 / 915 MHz devices. Out of the box it recognises 320+ device protocols, weather and soil/temperature sensors, TPMS tyre-pressure monitors, energy/water meters, doorbells, contact sensors and many remotes, and demodulates both OOK/ASK and FSK, printing each decoded device as a line of JSON (also CSV, MQTT, InfluxDB, syslog). It is itself the decoder: where Wi-Fi or BLE hand a PCAP to Wireshark, rtl_433 turns raw I/Q straight into named, fielded device events. Runs on RTL-SDR natively and on HackRF / other radios via SoapySDR.
