Both our phones are on the latest iOS update and our Geofence area is set to the end of our block. Very rarely does it not detect we are home by the time we open the garage door. How long is an extraordinarily long time?
It sounds like you may have had something prior to Hubitat's mobile as your presence sensor? If so have you thought about using both and tie them together with something like Combined Presence? When I first installed the Hubitat Mobile app and tried out the presence sensor I installed Combined Presence to use with Life360 and have been using it that way since as there are times (updates) where we get logged out of the Hubitat app and don't notice until it doesn't update its presence, there have also been numerous times where Life360 failed to update its location too and we had to click the Life360 refresh button to correct that if we noticed before leaving and returning.
The Combined Presence has kept my wife from walking into a blaring alarm a few times which would have affected her acceptance greatly, so it has definitely been worth having both forms of presence.
