Tradfri AR Project

This is meant as a proof of concept on controlling Ikea TRÅDFRI lights using Augmented Reality. It might not be very practical since controlling your lights with a physical switch (or the Ikea app) is way faster. But nonetheless I found it a nice project for myself started with AR.

Libraries used

• AR.js - GitHub -> this project includes a custom build which contains a fix for custom markers
• a-frame - GitHub
• node-tradfri-argon - NPM

Application architecture

It uses NodeJS to serve a static webpage. Using ExpressJS to expose a simple API to control the TRÅDFRI lights. The node-tradfri-argon package relies on libcoap.

Installation

• Clone this repo
• Install libcoap (instructions here)
• Modify the package.json 'start' script, set your params: COAP_CLIENT_PATH, HUB_IP_ADDRESS and SECURITY_ID (the ID on the bottom of your Ikea Hub)

$ npm install
$ npm start

What works so far

It has 2 entities, each has its own marker (Hiro and custom marker). The custom marker can switch my dining room light on (in 3 'colors').

Todo

• Make the object clickable using touchscreen instead of the small black circle pointer
