Philips Hue Motion detector corner mount

This is a corner mount for a Philips Hue motion detector. The design goal was to mount the detector in the top corner of a room at a slightly downward pointing angle so that the detection will be triggered when someone is actually in the room.  As an added benefit, you can just leave the battey cover off the motion detector since you can't really see the back when its mounted high up in a corner.  I have these in practically every room in the house now.  No installation or hardware needed. It just sits there like an elf on a shelf peering down at you from above.
