| `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 -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 wint `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`.

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`.
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 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
