Bilight is an open source mobile application and it has a active repository on github.
Github link Bilight
A simple Android application that controls the iBox lamp, RGBW, RGBWW and Dual-White lightbulbs at the same time, without ever having to switch "Remotes" like in the original Milight application. Only compatible with the Milight v6 protocol(!)

By manually mapping a port to an iBox device on your network, this can be used for "out of home" control of your lights.
