I just created a first version of an API to handles LIFX devices in your LAN.
It has been created to make easy interactions with your LIFX devices in your LAN, without cloud connection.
If you are interested about the application, you can find it here: https://github.com/fberrez/horus
If you have any suggestions, I will be very happy to improve this API.
I hope it will help non-cloud users!
