I am now curious if they disconnect on signal strength or some sort of response time out as in a heartbeat packet not being returned in a timely manner.

That little extra bit of detail would be very informative, allowing for concepts like pairing with speakers as you move from room to room, or even doing geo-location in a house due to wifi signal strength from the AP.

The bluetooth signal strength seems to be only available to apps when a bluetooth device is discovered, so Automagic would have to constantly execute the bluetooth discovery process. The other devices have to be in discoverable mode at the time of the scan.

According to the documentation, the discovery process can also interfere with existing bluetooth connections:
Device discovery is a heavyweight procedure. New connections to remote Bluetooth devices should not be attempted while discovery is in progress, and existing connections will experience limited bandwidth and high latency.
I will test the procedure on a device when I find some time but it is unlikely that I can add this as a trigger or condition.
