Bad geofence

Since geofence relies on a daisy chain of tech, phone settings, phone cell updates, Ring app access... Ie, sounds useful, but no workee. Use the device setup wireless as the proximity sensor. Turn it on for maybe 15 seconds every 5 minutes to look for owner's phones. This way, it's "all in the family." Of course, need software to add family members' phones to the approved trigger list.
