Decision gist · record as of 2026-08-14
Yes, if you own an RFXtrx device and need Python-level control over RF signals. The library is actively maintained, has low install friction, and the copyleft license is standard for this project type. Not relevant if you don't have RFXtrx hardware.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a physical RFXtrx device connected via serial port and Python 3.9 or later.
- Low install friction with a single runtime dependency (pyserial).

What it is and what it does
pyRFXtrx is a Python interface to RFXtrx RF receiver/transmitter devices, which capture and send wireless signals from home automation sensors and controllers. It bridges the gap between RFXtrx hardware and Python applications, allowing you to receive events from wireless sensors and control RF-enabled devices. The library handles serial communication with the device via pyserial and parses incoming RF packets into usable Python objects.
The package targets developers building custom automation logic or integrating RFXtrx devices into broader systems. It requires only pyserial as a runtime dependency and supports Python 3.9 or later, making it straightforward to integrate into existing Python projects that need RF sensor data.
Use it for
- Receive wireless sensor data from RFXtrx-compatible devices in a home automation system.
- Build a custom Python daemon that listens to RF signals and triggers local actions.
- Integrate RFXtrx hardware with home automation platforms via a Python bridge.
- Send RF commands to control wireless devices through the RFXtrx transmitter.
