I’m trying to find the best way to tell my home automation setup when a family member enters or leaves the house. My first thought is Bluetooth because we each have phones with us at all times.
I did some digging and it looks like Apple requires a special auth chip to successfully pair an iDevice via Bluetooth. RovingNetworks makes a special model ([RN-41-APL) that works with the auth chip, but you cannot buy it unless you are part of the Apple 3rd party accessory program.
So here’s my question… What if I just want to discover when an iPhone is in range and then when it goes out of range. Will this (RN-41) allow that? I have no desire to pair or communicate via Bluetooth, just want to have something in my garage scanning for bt signals so I can turn on some lights and whatnot.
Thx!
