Introduction
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. The libgiod-python library is required to access the GPIO pins. Therefore, the GPIO character device is used instead of the old GPIO sysfs interface.
Supported hardware
Most generic 433/315MHz capable modules (cost: ~2€) connected via GPIO to a Raspberry Pi.
Compatibility
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
Dependencies
libgiod-python (available through most package managers as python3-libgpiod)
Installation
On your Raspberry Pi, install the rpi_rf-gpiod module via pip.
Debian/Ubuntu:
# apt-get install python3-pip python3-libgpiod
Fedora/CentOS:
# dnf install python3-pip python3-libgpiod
With pip installed:
# pip3 install rpi-rf-gpiod
