About:
rtl_433 is a generic data decoder for Sub-GHz wireless devices. It listens to radio signals from sensors like weather stations, tire pressure monitors, and utility meters, decoding and outputting the data in various formats. This tool enables users to integrate and analyze data from a wide array of consumer radio devices.
Key Features:
  • Supports hundreds of device protocols (weather stations, sensors, TPMS, etc.)
  • Multiple data output formats (CSV, JSON, KV, MQTT, InfluxDB)
  • Raw signal analysis and device discovery tools
  • Runs on Linux, macOS, and Windows
Use Cases:
  • Building a personal weather station dashboard with off-the-shelf sensors
  • Monitoring home utility meters (water, gas, electricity) remotely
  • Decoding vehicle Tire Pressure Monitoring System (TPMS) data
Alternatives:
  • rtl-sdr – Lower-level library for raw IQ sampling; rtl_433 uses it as a dependency for decoding.
