A feature-complete KNXnet/IP protocol stack in pure Javascript, capable of talking multicast (routing) and unicast (tunneling). Adding KNX to your Node.JS applications is now finally easy as pie.

• Wide DPT (datapoint type) support (DPT1 - DPT20 supported)
• Extensible Device support (binary lights, dimmers, ...)
• You won't need to install a specialised eibd daemon with its arcane dependencies and most importantly,
• If you got an IP router and a network that supports IP multicast, you can start talking to KNX within seconds!

Make sure your machine has Node.JS (version 4.x or greater) and do:

npm install knx

At last, here's a reliable KNX connection that simply works without any configs. To get a basic KNX monitor, you just need to run this in Node:

var knx = require('knx');
var connection = knx.Connection({
 handlers: {
  connected: function() {
    console.log('Connected!');
  },
  event: function (evt, src, dest, value) {
  console.log("%s **** KNX EVENT: %j, src: %j, dest: %j, value: %j",
    new Date().toISOString().replace(/T/, ' ').replace(/\..+/, ''),
    evt, src, dest, value);
  }
 }
});

Ahhh, KNX telegrams, what a joy:
