Sending and receiving 433/315MHz signals with low-cost GPIO RF modules on a Raspberry Pi

Project description

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: ~2€) connected via GPIO to a Raspberry Pi.

433modules

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
