rpi-clickety

A node library that can receive, decode, and transmit 433Mhz remote controlled outlet signals using your raspberry pi. Inpired by rc-switch. I made this to control the switches I have at home (HS2260A chip).

Features

• Sniff transmissions and output decoded values
• Output raw pulse timing data (as base64)
• Code based transmit
• Can also transmit based on raw pulse timing data

Installation

This module depends on the JS pigpio library for high-speed gpio twiddling so follow the installation instructions there.

Usage

Note: I used the cheapo 433Mhz transmitter/receiver modules that can be obtained for under $5. All testing was done on a Rpi Zero WH.

⚠ Note on pin numbering: The underlying pigpio library uses the Broadcom GPIO numbers so make sure you are using the correct numbers.

Receiving

Setup:

• Pi pin 1 (3v3) <-> Receiver Vcc
• Pi pin 6 (GND) <-> Receiver GND
• Pi pin 13 (GPIO27) <-> Receiver DATA

//Note we are passing 27 not 13 for pin param
const receiver = new Receiver(27);

//receiver is an event emitter that will emit received codes
//along with other useful info.
receiver.on('code', (data) => {

  console.log(data.code); //Print decimal code
});

receiver.listenStart();

Transmit

Setup:

• Pi pin 2 (5V) <-> Transmitter Vcc
• Pi pin 6 (GND) <-> Transmitter GND
• Pi pin 11 (GPIO17) <-> Transmitter DATA

const tx = new Transmitter(17);
tx.transmit(1406220); //Send decimal code
