Hi,
just want to share the LYT8266, a LED light bulb based on ESP8266 that I’ve contributed to develop. It compares directly with Lifx or others with the difference that you can program it yourself (by the way has also a lower price).
I’ve developed the support for Souliss, so that you can use these bulbs also with openHAB through the Souliss Binding, but in any case is just an ESP8266 with some LEDs into an E27 case.
If you want to read more about, here a link or ask me on this topic
Dario.
