rtl_433 test samples

rtl_433_tests contains the test suite for rtl_433

This repository contains lots of signal recordings that are supported by rtl_433.

The regtest system is not developed yet, but accepting signal recordings.

Installation instructions

Clone this reposity to the root of rtl_433


Enter the directory and run make test. The output will tell if the tests failed or not.


Run rtl_433 with rtl_433 -S unknown and wait for you signal to be detected. When it is detected note what gfile name it has. This file can now be run through rtl_433 offline:

$ rtl_433 -r g001.cu8

Look at the -A analyze mode output and include a timing description if you like. You can also include a flex decoder (-X ...), don't include raw analyzer output.


Add signals by creating directories and then add the sample files. We need to watch the repo size, add only about 5 interesting sample files. If you have more interesting samples (e.g. to recover a checksum), include the bitbuffer codes in the README.md.

You can rename the sample files to add information, e.g. replace g001 with low_battery. Do not remove the frequency and sample rate information.

Also add a README.md and perhaps pictures of the hardware. E.g. front.jpg, back.jpg, inside.jpg. Limit the picture size to about 50k by cropping and compression.

Samples are contained in directories with the scheme: tests/GROUP/DEVICE/SET

  • GROUP is optional and usually the manufacturer or common protocol, e.g. lacrosse
  • DEVICE is the device name, e.g. tx141w
  • SET is optional and used for different actual devices, not functions. E.g. 01
  • Each level should have a README.md describing that level.

To discuss the device and decoding open an issue on rtl_433open in new window. Issues in rtl_433_tests are used for the acutal building and testing only. PRs on rtl_433_tests should only discuss the merging and not the device.
