I’ve got a iPhone set as the a persons device tracker. iPhone Geocoded Location is updating with every move.
The person shows updated 12 hours ago. why?
just wanted to ask the same, did you ever figure it out?
I was wondering if we need to open our local HA for remote access so the phone can send updates to the HA at home 
I also found this article but I got lost on the tracker part
Better Presence Detection in Home Assistant
If your using apples companion app person.xxx looks to have only
home, away, or known place.
Looks like I do get those updates on location change.
Has the phones location move a major amount to update the phone?
assuming you have device_tracker.xxx set up for the person?
