Can this differentiate between multiple humans gesturing at the same time (intentional or otherwise)? What about pets moving around or turning the shower on?

Your pet turns the shower on? That sounds like a real problem

One of my cats has actually done this a couple of times. He walks along the ledge around the bathtub and squeezes past the shower handle, forcing it away from the wall and turning on the water. It's a problem that seems to have solved itself, because it scares the shit out of him and he gets wet.

probably not, home automation has been "right around the corner" for 60 years.

That's sort of tangential to my point. There are reasons we might not want phased array radar systems picking up every move we make in the privacy of our own homes, independent of home automation applications, which is I presume what the post I was responding to was getting at. My point is that those desires of ours are irrelevant when it comes to whether or not the applications we don't want come to pass, because at…

It's your own phased array radar system--oooh such a scary word! It's an input device. If you're worried about it telling Google that you spent 30 minutes on the toilet this morning, then either monitor the traffic for odd connections or just block it from making any connections outside your LAN.

Just wondering, do standard wi-fi chipsets provide the raw signals needed to implement things depending on spectrum-analysis like this? Some super-raw mode? How about Bluetooth chips? Sound chips (for supersonic)?

it should have been "ultrasound" instead of "supersonic" ;)

Determining when nobody is home is already not that hard. Just ping the devices registered with DHCP, over a few days. Should be fairly easy to identify which devices are phones and alert you when none of the phones are responding.

It's not necessarily your own. 2.4GHz goes through walls.

It's not nearly that expensive, though. A light socket is in the neighborhood of $15. A wall socket is less than $25. A transceiver is $30. For just over $100 you can get the controlling software, two wall switches, two light sockets, and a transceiver. http://www.thehomeautomationstore.com/x10-home-automation.ht...

Oh, but don't use CFL bulbs with those wall switches or light sockets. ...and good luck determining whether the device is on or off.

That's not the point, and there are units which address those concerns. The point is, home automation is not "right around the corner", it's here today and it doesn't take a millionaire to have a smart home. The sticking point is not technology nor is it money, it's that people have realized they don't really want that.

Just need to ensure a proper counter measure is (1) available and (2) legal.
