I'll just wrap my router in aluminium foil, that'll do it.

Any open source implementations of this?
Yeah this has been around for some time now, here's a paper on the implementation of it.
I'm guessing it assumes you're carrying your phone and infers motion from changes in the signal?
Or just uses the phone connecting and disconnecting to signal departure and arrival, in which case Home Assistant has done that for awhile now.
Or don't! (at extra cost)
She kinda bad tho
Alert: the Wi-Fi has detected high-waisted mom jeans.
colonel im trying to infiltrate a home but the clap of my asscheeks keeps being detected by the wifi signal
Pretty sure this was mentioned in Cryptonomicon (1999).
Please, everyone:
This tech is still relevant in 2025?
What tech? Wifi?
I thought OpenWrt was kind of dead. Everyone uses pfsense as their open source router.
IMO, pfsense is for if you want to use an x86 PC as a router, while OpenWRT is for if you want your ARM-based commodity home router to run open source firmware.
it's not just for routers. you can (and should) use it on your access points.
I have six APs in my house for 100% WiFi coverage inside and outside my home.
Iβm actually so incredibly lazy I use a firewalla purple. And I love it. Youβll never take it away from me! Hiss!!!!
Are you thinking of ddwrt? OpenWrt is alive and thriving
ddwrt is what I was thinking of
Can second the other comments. OpenWRT is alive and well in parallel to PfSense. Different use cases for each.
All this is implying is that they are capturing this data anyways and offering you a peek at it for money with the guise that its for your safety.
There is likely no way for you to shut it off tracking you everywhere in your own home unless you pay them to access the settings for this feature.
They likely can track you behaviors with this and know when you take a shit, when you jerk-off/fuck your spouse, when you watch media, etc using machine-learning on the wifi specrum of your locations, signal shape, and duration.
Fuck this crazy invasive shit to piss.
Ask for just a plain modem and buy your own WiFi router. If that isn't an option, disable the routing functions and turn off the WiFi and buy your own router.
Does owning my own hardware prevent the service provider from getting this data?
Yeah, they used something like fluctuations in the WiFi signal, so you can turn it off. I suppose they could broadcast secretly without an SSID, but there are apps that will show it, so I doubt they would.
They can also see more than just movement: https://www.popularmechanics.com/technology/security/a42575068/scientists-use-wifi-to-see-through-walls/
They would have to have access to the wifi piece specifically, so asside from them hacking the router, which is unlikely..
It makes it a lot less likely.
I haven't had a provider supplied modem or router in well over a decade. Not everyone has the know how to do this but it's not hard to learn and they should learn.
How hard it'll be depends on the provider. My provider's customer support explicitly told me that it is technically allowed but it is their policy to offer absolutely no help with that whatsoever for "liability reasons", and I'd be on my own if I got my router stuck in a misconfigured bridge mode where I can't access any settings anymore to fix things. They also told me to find my subscriber credentials on my own if I wanted to use a 3rd party modem.
Reminds me of The Dark Knight when Batman activates something similar using cell signals.
We really ought to stop fucking creating the Torment Nexus, jfc.
Awesome tech, if (and only if) you control it end to end, with no corporation involved in that process.
That's why you buy your own router.
I'm using chromecast for streaming to my television. But I accidentally cut my internetcord and guess what doesn't work without internet eventhough it doesn't strictly need internet? Exactly, I'm getting rid of the chromecast soon.
Your telling me a streaming device doesn't work without internet. I'm shocked shocked I fell you.
It should be able to work on lan as well, in my opinion
Are you trying to cast or screen share? Screen share should work over LAN I think.
Screenshare does work over lan, according to the documentation, but the chromecast doesn't even start up properly. It onky says (full screen) there is no internet connection.
When streaming content to a chromecast it usually makes a direct connection to the content source, not going through the device you're casting from. In limited cases like when sharing your screen to the chromecast it does only go from your device to the chromecast without internet, but that's rarely used because it's power and data intensive to your device. I guess you're right on the internet not being 'strictly' needed but it's used for a reason.
Should still buy your own router though, and move away from google services π
Yeah "google bad" but this isn't one of those instances. They've been very upfront about the functionality of the Chromecast for a very long time
