I’ve started work on a library for the esp8266 in order to control lifx bulbs via the HTTP API. You can follow it’s progress here:
As of right now, it can only query the status of the bulbs, and find things like is it on or off/color/name that sort of thing. It can query the status of the bulb to find things like color/brightness/hue, as well as toggle the power.
Updated post about what I’ve since added here: http://www.joeybabcock.me/blog/arduino/arduino-esp8266-lifx-library-update-change-color-and-brightness-of-bulbs/
