I have a smart light that interacts with wifi, add one more and you could use them to triangulate at least a rough position possibly. Enough to tell if someone is in the house at least and maybe an estimate of how many people. Sci-fi dystopia shit really if it is truly possible.
It requires a lot of nodes! Like if you’re placing 6 wifi end points in every room that’s pretty bad opsec even without this.
