* To use set the device to "philipshue".

* Uses the official Philips Hue API (http://developers.meethue.com).
|

* Framegrabber should be limited to 30 Hz / numer of lights to avoid rate limitation by the hue bridge.
|
|
* Create a new API user name "newdeveloper" on the bridge (http://developers.meethue.com/gettingstarted.html)
