You know what you cant turn off? TPMS. I mean you can remove them from your car, but those little guys broadcast and with the right equipment you can track cars with them.

Yes. The IDs are unique, fixed, and easy to pick up. You have to broadcast a low-frequency signal first to enable them and they'll emit a signal. There are several projects on GitHub to pick them up, and I've successfully done it.

Did you do anything useful with the data? I'd love to just have a raspberry pi scanning and logging them with timestamps to archive with video.

No, but I've been collecting all this data for a while and trying to see if there's a security business to be built around this. I do a lot of "RF" projects, so this is a natural extension.
