Knx NPM | npm.io

KNXnet/IP for Node.JS

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!

Installation

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

npm install knx

Usage

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:
