Node TRÅDFRI API - Node.js Argon (v4.x+) supported

Node API to control IKEA TRÅDFRI (TRADFRI) Lights. Tested on node version 4.4.7

The package is a refactoring for older versions of Node.js (from 4.x) support of node-tradfri by morzzz007

• Every method returns a Promise. See example under Usage for a detailed description
• Package has been tested on Node.js v4.4.7
• P-throttle is used to make sure that all CoAP client calls are in series (to avoid execution blocking)
• RSVP lib is used to manage Promises in the library
• Thanks morzzz007 for creating node-tradfri. It made it fairly simple to increased the backlevel support

Installation

npm install node-tradfri-argon --save

CoAP

This library uses libcoap with tinydtls to send CoAP requests. Build instructions are described below see this section. and set the coapClientPath config setting to point to your library.

Usage

  var tradfri = require('node-tradfri-argon').create({
    coapClientPath: './lib/coap-client', // Path to coap-client
    securityId: '<security_id>',        // As found on the IKEA hub
    hubIpAddress: '<hub_ip_address>',    // IP-address of IKEA hub
    identity: '<any string representing the connection>' //Identifying the 3rd party client
    //,preshared_key: '<preshared key>' //If register has already been performed in the identity
  });

  /* First time you need to register the connection and the result is used in subsequent calls. Make sure that you save the preshared key that is returned. It is unique per `identity` as specifid in when creating the tradfri object as above */
  tradfri.register().then(resp => {
      tradfri.setPresharedKey(resp.preshared_key);
  });

  tradfri.getDevices().then((devices) => {
    devices.forEach((device) => {
        console.log(device);
    });
  }).catch((error) => {
    // Manage the error
    console.log(error);
  });

  // or

  tradfri.setDeviceState(65537, {
    state: 'on',
    color: 'ffffff',
    brightness: 255
  }).then(...).catch(...);

API

Basics

Every exposed method is asynchronous and returns a promise.

Using the typical promises approach:

  tradfri.getDeviceIds().then(deviceIds => {
    // do something
  });

Compiling libcoap

A number of versions are available in the lib folder but if it is required to recompile the library the instructions are below.

Linux

Install libcoap as descibed below for Debian/Ubuntu/Raspbian: (credits to homebridge-tradfri)

$ apt-get install libtool git build-essential autoconf automake
$ git clone --recursive https://github.com/obgm/libcoap.git
$ cd libcoap
$ git checkout dtls
$ git submodule update --init --recursive
$ ./autogen.sh
$ ./configure --disable-documentation --disable-shared
$ make

OSX

Use brew to install the prerequisites and then clone the git repo and build the library as described below.

$ brew install libtool
$ brew install automake
$ brew install autoconf
$ git clone https://github.com/obgm/libcoap.git
$ cd libcoap
$ git checkout origin/dtls
$ git checkout -b dtls
$ git submodule update --init ext/tinydtls
$ cd ext/tinydtls
$ autoreconf
$ ./configure
$ cd ../../
$ ./autogen.sh
$ ./configure --disable-shared --disable-documentation
$ make

Where is the client?

After compilation you'll find the coap-client binary in ./examples. Simply refer to the coap-client location when initiating node-tradfri-argon. E.g.

  var tradfri = require('node-tradfri-argon').create({
    coapClientPath: '/home/pi/libcoap/examples/coap-client',
    securityId: '2wsY2QSL65k5iD8i',
    hubIpAddress: '192.168.2.193',
    identity: 'mycustomapp',
    preshared_key: '3PKkShwAP5t2u2lI'
  });
