Xfinity using WiFi signals in your house to detect motion

There is no technical solution for this unless you want to invest billions/trillions in building new computing and networking platforms created with privacy in mind.

ISPs will always have the ability to at least deduce whether a connection was used, the MAC address, and it there is WiFi, unfortunately whether people are physically present.

If we look at the roadmap for WiFi/phones/etc, they will soon gain the ability to map out your home, including objects, using consumer radios.

"There is no technical solution for this"

This isn't really true. The easiest technical solution to the problem of ISPs using your wifi data is to simply use your own WiFi router which does not send the data to them.

They can still deduce this from the traffic patterns.

They can map your home and motion with traffic patterns?

The OP was also talking about deducing presence based on connections and traffic patterns, which using your own WiFi AP isn't going to mitigate.

I don't think there's any reliable way around that. They can do that with real-time power meter monitoring even if you don't have an internet connection.

Good luck to them for those of us who have set up a tailscale exit node in our network and use it whenever they are 'roaming'.

They can see the WireGuard traffic coming in and correlate it with traffic out. WG traffic is easily identifiable.

I have tons coming in all the time some of it goes out some of it does not.

So use a vpn.

With a VPN, your ISP may not know where packets are going, but they can still see packets moving. So, unless your VPN is injecting dummy data to mask all patterns (possible, but not common), your ISP is going to have a good idea if someone is home or not.

So does your power company with real-time meter monitoring. Masking that is much harder and would be more expensive if it's even possible.

Creating useless traffic on a random schedule is pretty trivial.

I have a better solution: just use your neighbour's wifi :P

pay him with a pack of beer
