Hi all,
I have sideloaded the Flic apk on my Nvidia Shield TV in order to use it as "Flic hub" and while it requires a mouse to be plugged-in for configuration, it works fine.
I wish the app installation from the Play Store wasn't blocked (I understand the app is not usable with a remote, so it can't be presented as an Android TV app, but maybe it could be available from the Play Store web interface as Google does with Chrome)
As the Shield is always on, it is the most reliable device to control my Hue lights and my Sonos system.
