While on multiple Android devices clean the App is reliable and also an account at myHue works, so this is achieved not on the FireHD 6. There comes a message that the device is not authorized for use by myHue. Annoying.
The local control of Hue Bridge, however, works without problems and the app does what it should. The extent of local control, although I find Hue Pro (in PlayStore available) better, as well as a music-based control is possible here, but the surface of the Hue app is appealing design and operation intuitive.
However, can be without myhue no Community Themes reload and control of the road is not working. For 2 star deduction.
