The next version of DreamScreen will be able to work over WiFi and will eliminate some of the problems that can arise when just using Bluetooth. We are still working on a connection to the Hue, but have run into some issues (such as differing colors) that have slowed this progress.
Apparently the original DreamScreen model isn't able to handle this (the Bluetooth connection is too unstable for this). But they have said on their current Kickstarter page, that the new DreamScreen HD/4K models (with WiFi connection) WILL get Hue support. They have already done some preliminary work on the interface, and they expect to have it ready by November.
