It would be great if there were some open source tool kits for this. If the technology is going to exist it should be in the hands of the people.

Damn, I thought I called it 8 months ago, but that was about reading heart rates using wifi...

Yeah, if this shit has to exist, at least let me use it for presence detection in Home Assistant without having to buy separate sensors or something!

Have fun watching me be balls deep in my partner, fed boys. Be jelly cause you can't fuck like me.
I'm already envious 🙂↕️
I'm sure you fuck good or will one day if you haven't already.
Very interesting concept. I was curious about how in the hell this could be done. This article explains the general method.
When an inert object like a person moves around between the router and stationary connected devices like computers and printers, it interferes with the signal. The pattern of interference plus math can be used to plot the movement of the object - and even measure subtle changes like hand gestures. Home security software from companies like Xfinity can already use this tech to send you an alert when something is moving around in your house, without needing additional hardware. Imagine an informercial where a guy holds up a handful of "clumsy motion sensors" with wires sticking out of them, and "confusing instructions". Not if you just let your router do it!
As far as being a new and sinister means of surveillance, evil companies could already theoretically tap into anybody's motion sensors or security cams. The difference with WiFi tracking is that you wouldn't necessarily know it's there.

From what I've read this is built into the required wifi router for Xfinity. I discovered this when I signed up for Xfinity fiber, had the fiber installed and setup and then cancelled it the same day, because of this and not being able to buy and run my own hardware, and needing to install an app on my phone to manage the router, and apparently not being able to choose my DNS. They required that I rent their hardware for an additional $15/mo. Oh well, at least fiber is in the house now, if anyone wants it in the future. I sure won't be paying them to spy on me.
Fuck Comcast, still.
app to manage router
This shit was a pain in the ass and now learning about this makes me feel even more pissed off as a customer
Damn. Put a faraday cage around the router and plug in your own router to a LAN port.
Wrap it in aluminum foil.
Whilst this sounds a lot like a foil hat joke, that's literally the easiest way to wrap something in a conductive material cage (i.e. a faraday cage).
If you don't want it to look ridiculous, put it inside a box whose inside has been lined with aluminum foil.
Mind you, personally I too would just cancel that shit, but the option is there to carry on using it whilst blocking its radio emissions.

There is a project I can't find now which uses an esp32 to create a presence detection system that integrates with home assistant and it uses wifi.
I know of ESPresense, but that only tracks your phone, not your body..

How do they identify a particular person though? I get you could see people as present or not or moving around the room, but it's insane that they would be able to tell facial features etc.
A paper from around a decade ago talked about using WiFi to identify key strokes so with large data models we have today I would assume they could get pretty good fidelity on a person. Maybe not enough for “beyond a reasonable doubt” but probably enough where your WiFi company is selling your data on what you do at home

Comcast Is watching you masturbate. Awesome.
I mean, they kinda already were.
Especially if they've been opening all those videos I've sent
may soon be able to
That means "yesterday's spy tech" that now they will leak to public, because they have a way better way.
I'm not sure of the current state of my tinfoil hat.

Building codes should probably include Faraday-cage type shielding.
That would prevent cell signals from inside, making it harder to (e.g.) call the fire department, or an ambulance.
the return of landlines is nigh
Honestly, we'd be better off at this point.
