Missing
Nureva Room Manager monitors for Nureva Wall hardware and once connected, activates all the relevant tiles. If a Nureva Wall system is not present or not connected, the associated tile is removed from the interface.
Grayed out
Tiles are grayed out if Nureva Room Manager finds a problem with Nureva Wall systems. An accompanying message would indicate problems such as no hardware connection or if there are missing (software) components for the connected hardware.
