Read the Test Data section at the bottom.
Compiling rtl_433 requires rtl-sdr to be installed.

cd rtl_433/
mkdir build
cd build
cmake ../
make
make install
Installation using autoconf:
cd rtl_433/
autoreconf --install
./configure
make
make install
rtl_433 -h

[-p <ppm_error] Correct rtl-sdr tuner frequency offset error (default: 0)
[-s <sample rate>] Set sample rate (default: 250000 Hz)
[-S] Force sync output (default: async)
= Demodulator options =
[-R <device>] Listen only for the specified remote device (can be used multiple times)
[-l <level>] Change detection level used to determine pulses [0-32767] (0 = auto) (default: 8000)
[-z <value>] Override short value in data decoder
[-x <value>] Override long value in data decoder
= Analyze/Debug options =
[-a] Analyze mode. Print a textual description of the signal. Disables decoding
[-A] Pulse Analyzer. Enable pulse analyzis and decode attempt
[-D] Print debug info on event (repeat for more info)
[-q] Quiet mode, suppress non-data messages
[-W] Overwrite mode, disable checks to prevent files from being overwritten
= File I/O options =
[-t] Test signal auto save. Use it together with analyze mode (-a -t). Creates one file per signal
Note: Saves raw I/Q samples (uint8 pcm, 2 channel). Preferred mode for generating test files
[-r <filename>] Read data from input file instead of a receiver
[-m <mode>] Data file mode for input / output file (default: 0)
0 = Raw I/Q samples (uint8, 2 channel)
1 = AM demodulated samples (int16 pcm, 1 channel)
2 = FM demodulated samples (int16) (experimental)
3 = Raw I/Q samples (cf32, 2 channel)
Note: If output file is specified, input will always be I/Q
[-F] kv|json|csv Produce decoded output in given format. Not yet supported by all drivers.
[<filename>] Save data stream to output file (a '-' dumps samples to stdout)

Examples:
| Command | Description |
|---|---|
rtl_433 |
Default receive mode, attempt to decode all known devices |
| `rtl_433 -p NN -R 1 -R 9 -R 36 -R 40 | Typical usage: Enable device decoders for desired devices. Correct rtl-sdr tuning error (ppm offset). |
rtl_433 -a |
Will run in analyze mode and you will get a text description of the received signal. |
rtl_433 -A |
Enable pulse analyzer. Summarizes the timings of pulses, gaps, and periods. Can be used in either the normal decode mode, or analyze mode. |
rtl_433 -a -t |
Will run in analyze mode and save a test file per detected signal (gfile###.data). Format is uint8, 2 channels. |
rtl_433 -r file_name |
Play back a saved data file. |
rtl_433 file_name |
Will save everything received from the rtl-sdr during the session into a single file. The saves file may become quite large depending on how long rtl_433 is left running. Note: saving signals into individual files wint rtl_433 -a -t is preferred. |
This software is mostly useable for developers right now.
The first step in decoding new devices is to record the signals using -a -t. The signals will be
stored individually in files named gfileNNN.data that can be played back with rtl_433 -r gfileNNN.data.
These files are vital for understanding the signal format as well as the message data. Use both analyzers
-a and -A to look at the recorded signal and determine the pulse characteristics, e.g. rtl_433 -r gfileNNN.data -a -A.
Make sure you have recorded a proper set of test signals representing different conditions together with any and all information about the values that the signal should represent. For example, make a note of what temperature and/or humidity is the signal encoding. Ideally, capture a range of data values, such a different temperatures, to make it easy to spot what part of the message is changing.
Add the data files, a text file describing the captured signals, pictures of the device and/or a link the manufacturer's page (ideally with specifications) to the rtl_433_tests github repository. Follow the existing structure as best as possible and send a pull request.

Please don't open a new github issue for device support or request decoding help from others until you've added test signals and the description to the repository.
The rtl_433_test repository is also used to help test that changes to rtl_433 haven't caused any regressions.
