Hacking into Internet-Connected Light Bulbs

Re:Hacking into Internet-Connected Light Bulbs by kevinbowman on Friday July 04, 2014 @10:05AM (#7988748)

I have the pleasure of having been involved with one of the first network protocol reverse-engineers of the LIFX [0], and off the back of that hacked together a NodeJS library and a Wireshark dissector. I've updated the NodeJS lib to handle the new firmware (it does more over UDP, whereas it used to use a mixture of UDP and TCP) but not the dissector yet.

There's absolutely no authentication on the network protocol at all; as long as you're in the same network as the bulbs then you can send UDP packets and control the bulbs. I imagine this is a good and a bad thing; XBoxes automatically setting mood lighting when playing games etc... I'd rather they had to ask my permission before doing that, though.

They're a member of the AllSeen Alliance, so in the future they will probably support AllJoyn for control.

Thank you for sharing your work. I've considering getting some small cheap ir rgb bulbs and building some kind of "rPi/arduino lifx bridge" to control them all from the lifx side. This will help a lot. :)

There's also an official Ruby library for communicating with LIFX devices: https://github.com/LIFX/lifx-gem
