Add new event type for Bluetooth/Wifi proximity signal detection?

Can an event be logged for wireless signals Haven detects that pass a certain signal strength threshold? For example, if someone has a bluetooth device on and walks near the Haven device, then that event could be logged.

The issue proposes logging Bluetooth or Wi-Fi proximity signals above a signal-strength threshold, but names no files, tests, or entry points. First determine how Haven currently detects sensors and records events, then clarify the supported wireless signals, threshold behavior, privacy implications, and the expected logged event before implementation.
