Startup Idea : easy to do smart room kit (open source)

(sorry for my bad english) A kit and tutorial to mount your own smart room, example of what I did : Motion and object detector with a cam, white wall and everything else not too white (or it is just invisible ) and i track my key with a infra red cam. Also have a home vocal assistant not so smart for the moment but can shut the music or light down. The recognition is 100% accurate cause it is a close room, with a video projector i read my book on the wall staying in my bed and when I sleep (no more face detection for long time) the projector shut down. Also have a app on my android to be notified when somebody get in + photo. Is anyone interested in doing it ? I forget to add that we can play pose game inside
