A node.js module to interface with the GOP service from Greenwave Reality.

npm install greenwave-gop

This is an unofficial implementation, based on the GreenWave Reality Connected Lighting Solution as implemented in the Connected by TCPi product line.

No representation is made as to the fidelity of this implementation: in other words, the people making the lighting gateway are free to change the protocol at any time. If that happens, please contact the maintainer of the repository to take a look.

In fact, a change recently occurred:

• 'https' is now required instead of 'http'
• the gateway no longer advertises itself via the mDNS, but instead uses SSDP

Requests are sent via POST, with the body containing a URL-encoded XML document. Responses are also XML documents (minus the URL encoding, of course).

The protocol itself appears rich, and this module implements only the smallest subset necessary to discovery, rename, and on/off/dim bulbs.

var Gop = require('greenwave-gop');

var gop = new Gop().on('discover', function(controller) {
  controller.on('update', function() {
    var d, device;

    for (d in this.devices) if (this.devices.hasOwnProperty(d)) {
      device = this.devices[d];

      console.log('    device '  + device.did + ': ' + device.name);          

      controller.setBulbLevel(device.did, false); // off
      controller.setBulbLevel(device.did, true);  // on

      if (device.type === 'multilevel') controller.setBulbLevel(device.did, true, 50);
    }
  }).on('error', function(err) {
    console.log(this.tag + ': ' + err.message);
  });
}).on('error', function(err) {
  console.log('oops: ' + err.message);
});
