piswitch/example.js

Use your Raspberry Pi to control 433 MHz RC power sockets. Inspired by RC-Switch for Arduino.

var rc = require('./piswitch');

// The RC-Switch wiki and related material are very helpful:
//   https://code.google.com/p/rc-switch/

// This library is meant to be compatible, so any device that works with
// RC-Switch for Arduino *should* work here.

// Note that you'll need to export the pin with `gpio export [PIN] out`
// when using 'sys' (non-root) mode, which is recommended.
//   compare: http://wiringpi.com/reference/setup/
//   pin chart: http://pi.gadgetoid.com/pinout/

rc.setup({
    mode: 'sys', // alternative: change to gpio and use root
    pulseLength: 330, // this works for me, but 350 is very common
    protocol: 1
});
