I'll start building my new house very soon and I'm currently looking into finding a way to automatically detect when and where to turn lights on so that I don't have to hit switches or even use voice commands. There are "presence detection" devices available which are based on motion detection. They work pretty well at detecting motion. However, they utterly fail if you e.g. just sit still, reading a book. So I would say those devices should work pretty well for hallways, but for other rooms I have my doubts about their usefulness.

Now I'm wondering if maybe CastleOS could implement reliable presence detection via Kinect? I have no personal experience with Kinect so I don't really know how reliable it is to detect human presence anywhere in the room. The ideal/perfect solution would be if you could actually keep a reference of every human being in the house. E.g. CastleOS could detect 2 humans, one in the living room, the other in the kitchen. Then if the person in the kitchen leaves the kitchen and walks into the living room, the Kinect device in the kitchen could notify CastleOS that this person is leaving the kitchen through the door to the living room. And the Kinect device in the living room could take over and report that the person arrived in the living room, coming from the kitchen.

Do you think something like this would be possible if there's a Kinect in every room of the house? Would Kinect be reliable enough to do this? Maybe adding door sensors or additional motion detection devices into the mix would help making things even more reliable?

I could imagine very nice lighting behaviour based on this. E.g. CastleOS could even predict where a person is going and turn lights on in the "target" room before the person even enters that room. Or if there is a chain of rooms, or a very long corridor in a hallway, Kinect could follow the walk path of the person and turn lights on ahead of the planned path.

Other possible features could be me asking CastleOS: "Where is Anna?" and CastleOS could reply with "Anna is in the living room". Ok, maybe some people would find that too scary, so this feature should probably be optional. Personally, I'd love it. Of course asking for names would require CastleOS to know which person is which. But a first simple implementation would be to just support this for 2 people and then if one people asks for one of the known persons, it must be the "other one" in the other room. This way CastleOS wouldn't have to know who is who. Of course if CastleOS knew that, that would be even nicer, but I'm not sure how CastleOS could know.

I can't comment on specifics at this time, but the general concept you mentioned is something that is actively under development.

That sounds quite promising... smile I understand you can't comment on specifics. But maybe you can comment on what the Kinect can do in your experience and what it can't do? Where are the technical limitations? And if there are any, do you think maybe Kinect 2.0 will remove them? That is a topic I find *highly* interesting, because right now I don't really know how good the Kinect really is with this sort of stuff.

In your opinion: Should I invest the money to install those "conventional" ceiling mount presence detection devices? They cost about 139 Euros a piece, plus I'd have to tell the floor construction guys to prepare a hole in the concrete/cement ceiling in every room etc, which costs additional money.

Thanks!

I think your general line of thinking is in line with capabilities. And for your presence detection, yes go for it, because the more sensors the better, so it's not a wasted investment. They can all work together. Just make sure that whatever system you pick has some way of being controlled/monitored by a third party system.

Thank you, that's helpful. All sensors will be KNX.

We'll definitely be supporting KNX...we've had a lot of interest in us supporting it!

Cool. If at some point you need a KNX beta tester, just let me know.
