# JS library for LIFX bulbs
2+
3+
Some experimentation with trying to interpret the network protocol for [LIFX
4+
bulbs](http://lifx.co). This is very much observational, and an evolving
5+
investigation, so there's not very much info here and what there is is most
6+
likely incorrect or inaccurate. You have been warned.
7+
8+
This is based on my setup of 2 bulbs in a single group. That may or may not
9+
affect the network protocol.
10+
11+
Ideally, I'll end up with a nice little NodeJS library which can be used to
12+
build apps with.
13+
14+
## Files
15+
16+
There are 2 files:
17+
18+
* lifx.js which is the actual library
19+
* cli.js which is an example CLI app using the library
20+
