have a long uphill driveway(200'+) and need a way to tell when the mail has been delivered to cut down on trips to an empty box.

Pay attention as to what time they come and schedule you walk for
somtime after that. My carrier has never been later than 12:30. If
the hours are erratic then just wait til early evening. By then all
mail has been delivered.
