You don't have to iterate the whole array, either. Sort it by
ascending order of turn-off time. Keep a current position (index).
If the time of day is less than the turn-off time of the device at
the current position, do nothing. If time of day >= turn-off time of
current position, then turn it off and advance position until time of
day is again less than the turn-off time of device at the current
position. Only needs one timer, and scales to as large an array as
you want to keep.
