Yeah I have a million Bluetooth devices picked up but I've only put 4 of them so far into my Ha sensors. Fuck knows what the others are, but we have soany devices in the house that I can't keep track, then there's the neighbours' stuff too...
Interestingly I stumbled across a YouTube short yesterday about hacking an android device from only knowing it's Bluetooth Mac address, so theoretically I could really piss off my neighbours if they drove me to it.
