i made this to get a faster presence detection when i get home, i cant get a Ethernet cable there and a wifi esp32 bluetooth scanner almost never have time to detect me before i open the door.
This does.
Still only a custom component but maybe someone like the idea enough to make a real component!!?

i recommend using esphome manual install that way you can use the .bat or .sh to upload this easier

it uses irk to identify the phone mac, i used this to get it:

this is also where i got the initial idea and a startindpoint for the nrf bt code
also you can also see how many bt signals there are around you this is signals per sec averaged over 30sec
When using IRK to track the phone mac with this it will track other signals from your phone also, at least my phone spews out a lot of signals when i have it unlocked so i can detect that even if i don’t have a tracker transmitter running on my phone
Anyway i hope someone find this as interesting and hopefully as useful as me.
