I actually use several apps to control my hue bulbs.
Over than the hue bulbs, I also have 10 led candles with RF remote, that I control with my logitech harmony and a ir-rf bridge developed with an arduino.
My idea is to add the led candles as hue bulbs by means of a gateway developed on arduino (or raspberry).
Is there any library that can be used to add a virtual bulb to the hue bridge?
