Forked from https://github.com/milaq/rpi-rf. Modified rpi_rf_recieve script to include time stamp and file logging instead of standard out. Good for capturing activity after hours and matching back up with security cameras. Seems to work on most Raspian OS and hardware but script seems to need root to access the GPIO if you want to get up and running quickly.

Python module for sending and receiving 433/315MHz LPD/SRD signals with generic low-cost GPIO RF modules on a Raspberry Pi.

Protocol and base logic ported ported from rc-switch.

Most generic 433/315MHz capable modules (cost: ~2€) connected via GPIO to a Raspberry Pi.

Generic RF outlets and most 433/315MHz switches (cost: ~15€/3pcs).

Chipsets:

• SC5262 / SC5272
• HX2262 / HX2272
• PT2262 / PT2272
• EV1527 / RT1527 / FP1527 / HS1527

For a full list of compatible devices and chipsets see the rc-switch Wiki

RPi.GPIO

On your Raspberry Pi, install the rpi_rf module via pip.

Python 3:

# apt-get install python3-pip
# pip3 install rpi-rf
