rtl_433 (despite the name) is a generic data receiver, mainly for the 433.92 MHz, 868 MHz (SRD), 315 MHz, and 915 MHz ISM bands.
It works with RTL-SDR and/or SoapySDR. Activly tested and supported are Realtek RTL2832 based DVB dongles (using RTL-SDR) and LimeSDR (LimeSDR USB and LimeSDR mini engineering samples kindly provided by MyriadRf), PlutoSDR, HackRF One (using SoapySDR drivers), as well as SoapyRemote.

[-l <level>] Change detection level used to determine pulses [0-16384] (0 = auto) (default: 0)
[-z <value>] Override short value in data decoder
[-x <value>] Override long value in data decoder
[-n <value>] Specify number of samples to take (each sample is 2 bytes: 1 each of I & Q)
= Analyze/Debug options =
[-a] Analyze mode. Print a textual description of the signal. Disables decoding
[-A] Pulse Analyzer. Enable pulse analysis and decode attempt
[-I] Include only: 0 = all (default), 1 = unknown devices, 2 = known devices

Examples:
| Command | Description |
|---|---|
rtl_433 -G |
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 (g###_###M_###k.cu8). 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 with rtl_433 -a -t is preferred. |
rtl_433 -F json -U | mosquitto_pub -t home/rtl_433 -l |
Will pipe the output to network as JSON formatted MQTT messages. A test MQTT client can be found in tests/mqtt_rtl_433_test.py. |
rtl_433 -f 433535000 -f 434019000 -H 15 |
Will poll two frequencies with 15 seconds interval. |
This software is mostly usable for developers right now.
Note: Not all device protocol decoders are enabled by default. When testing to see if your device
is decoded by rtl_433, use -G to enable all device protocols.
The first step in decoding new devices is to record the signals using -a -t. The signals will be
stored individually in files named gNNN_FFFM_RRRk.cu8 that can be played back with rtl_433 -r gNNN_FFFM_RRRk.cu8.
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 gNNN_FFFM_RRRk.cu8 -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.

If you see this error:
Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.
