Library and CLI tools for interacting with RFlink 433MHz transceiver.

Project description Maintainability Test Coverage

Library and CLI tools for interacting with RFlink 433MHz transceiver.


  • Python 2.7 or 3.6 (or higher)


This package is created mainly as a library for the Home assistant Rflink component implementation. A CLI has been created mainly for debugging purposes but may be extended in the future for more real-world application if needed.

The package also provides a CLI utility which allows a single RFLink hardware to be shared by multiple clients, e.g. Home assistant + Domoticz or multiple Home assistant instances.


$ pip install rflink

Usage of RFLinkProxy CLI

$ rflinkproxy -h
Command line interface for rflink proxy.

  rflinkproxy [-v | -vv] [options]
  rflinkproxy (-h | --help)
  rflinkproxy --version

  --listenport=<port>  Port to listen on
  --port=<port>        Serial port to connect to [default: /dev/ttyACM0],
                         or TCP port in TCP mode.
  --baud=<baud>        Serial baud rate [default: 57600].
  --host=<host>        TCP mode, connect to host instead of serial port.
  --repeat=<repeat>    How often to repeat a command [default: 1].
  -h --help            Show this screen.
  -v                   Increase verbosity
  --version            Show version.

Share RFLink connected to serial port /dev/ttyACM1, the proxy will listen on port 2345:

$ rflink --port /dev/ttyACM0 --listenport 2345

Share TCP mode RFLink instead of serial port (eg: ESP8266 serial bridge), the proxy will listen on port 2345:

$ rflink --host --port 1234 --listenport 2345

Debug logging is shown in verbose mode for debugging:

$ rflink -vv --host --port 1234 --listenport 2345
