Reverse Engineering Ikea’s New Smart Bulbs – Hackaday

Over in Sweden, Czech, Italy, and Belgium, Ikea is launching a new line of ‘smart’ light bulbs. These countries are apparently the test market for these bulbs, and they’ll soon be landing on American shores. This means smart Ikea bulbs will be everywhere soon, and an Internet of Light Bulbs is a neat thing to explore. [Markus] got his hands on a few of these bulbs, and is now digging into their inner workings (German Make Magazine, with a Google Translate that includes the phrase, ‘capering the pear’).

There are currently four versions of these Ikea bulbs, ranging from a 400 lumen bulb designed for track lights to a 980 lumen bulb that will probably work in an American Edison lamp socket. These lights are controlled via a remote, with each individual bulb paired to the remote by turning the lamp on, holding the remote close to the bulb, and pressing a button.

Inside these bulbs is a Silicon Labs microcontroller with ZigBee support, twelve chip LEDs, and associated electronics that look like they might pass the bigclivedotcom smoke test. After tearing apart this bulb and planting the wireless module firmly in a breadboard, [Markus] found he could dim a pair of LEDs simply by clicking on the remote. Somewhere in these bulbs, there’s a possibility of doing something.

As with all Internet of Things, we must ask an important question: will it become part of Skynet and shut down the Internet, like webcams did last summer? These Ikea bulbs look pretty safe in that regard, as the bulb is inexorably tied to the remote and must be paired by holding it close to the bulb. We’re sure there are a few more interesting exploits for these bulbs, so once they’re released in the US we’ll take a look at them.
