Anybody else disturbed by the existence of this comcast website, or is my tin foil hat two sizes too big?
Unfortunately, her budget is a little tight to pull off many of the options right now, and a few extra locks and some security window film are taking precedent. That got me thinking about some cheaper options initially some things using old/cheap cell phones. I haven't been able to find an app that quite does what I have in mind, I may get around to writing it one of these days.
Then I thought about how stores track the mac addresses of people's phones and their locations inside stores. I did a little searching to find some of the old articles I'd read on the subject and open source code. This will also take some effort to get it to do exactly what I want and maybe some special hardware that could handle the temperatures in the garage, but a pi or cheap router will probably do.
In my searches, I stumbled on this little gem (link modified to prevent crawling and all you can see is a log in page)
