I just would add that with hardware scheduler DeviceDisappeared signal works
fine if there two remote devices in the field, and doesn't work if there is
only one remote device:

You may just have to wait longer to get the DeviceDisappeared signal
the fact the you turned off the device doesn't mean it will instantly
disappear it may happen that bluetoothd is idle waiting for scheduler
to start another discovery round (use Discovering property to check
that.). I will double check if there is some logic problem while
emitting DeviceDisappeared but I remember fixing it myself last time
and have no complaining since then.
I connected to PropertyChanged signal:

# turn device off
# And then no signal. At all. You even may go and drink cup of coffee or
smth :) There won't be any signal. But LED on my dongle indicates mode
changing: waiting (blinking), inquiry (permanent light), waiting, inquiry...
