If i buy Philips Hue Play Gradient Lightstrip, and install this app on my shield, would the gradient lightstrip then work with all its colors? or will it be one fixed colar at a time? (in other words will the gradient light work). ?
Yes, the Philips Hue Gradient will show multiple colours in Hue Essentials Sync (with a Hue bridge). See for more information: Sync (Entertainment) on your phone or Android TV
Please also read through the linked topic above for more information about the Sync feature.
