I’ve been playing with the other features of the Hue bulb, and I’ve updated the deviceType in a new branch on GitHub (enhanced features branch) adding a bunch of stuff that zigbee does natively in ZLL and providing greater flexibility. The additional custom commands can be called from custom SmartApps. I plan to create enhanced versions of other zigbee bulbs and a set of SmartApps to take advantage of the new features, so please let me know what you want to see.
