IKEA Trådfri Gateway plugin for Homebridge.

• Automatic discovery of the Trådfri gateway
• Turn on/off lights
• Adjust the brightness

• Adjust color temperature (figuring out how to do this the best way)
• Make the plugin work with third party HomeKit apps
• Better error handling and logging

1. Install Homebridge using: npm install -g homebridge
2. Install this plugin using: npm install -g homebridge-tradfri
3. Update your configuration file. See the sample below.

The PSK (Pre-Shared Key) can be found printed on the bottom of the IKEA Trådfri Gateway. This plugin makes use of coap-client which is part of libcoap.

The plugin comes with prebuilt x86-64 binaries for macOS and Linux. There is no need to compile coap-client if this is what you're using. If not, you'll need to compile coap-client yourself and use the config property coapClientPath to point to the location of the coap-client binary.

"platforms": [{
    "platform" : "Tradfri",
    "name" : "Tradfri",
    "psk" : "23asqw9123j33",
    "coapClientPath": "/usr/local/bin/coap-client" // OPTIONAL: See above
}],

Installing libcoap as per the following instructions for Debian/Ubuntu:

$ 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
$ sudo make install

You'll find the coap-client binary in ./examples
