rpi-rf
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.
Supported hardware
Most generic 433/315MHz capable modules (cost: ~2โฌ) connected via GPIO to a Raspberry Pi.
Compatibility
Generic RF outlets and most 433/315MHz switches (cost: ~15โฌ/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
RPi.GPIO
Installation
On your Raspberry Pi, install the rpi_rf module via pip.
Python 3:
# apt-get install python3-pip # pip3 install rpi-rf
