BLE MAC logging question

Hi all,

I am wondering if BLE MAC logging could be used for security purposes. If I have a BLE proxy setup near my entrance door and a thief were to try to break in and was ignorant enough to keep their phone on them, could the proxy record their MAC address? Would it be possible to setup an automation for this kind of scenario?

I am an HA newb and barely understand what I’ve accomplished so far but am really looking forward to implementing all the ideas I have.

Thanks all

Many phones randomly change their mac addresses.

Thank you for replying. I did not realize that. Guess I will rely on great camera placement.
