This doesn’t happen all of the time, but occasionally the WC Presence device quickly changes from “present” back to “away” and back to “present” in the span of seconds. See attached screenshot.
Any idea why this might be happening?
Why is my "WebCore Presence" quicky changing from "present" to "away" to "present" when I arrive at home?

usually because roads are curved. 
at some point on the approach to home you are closer as the crow flies then move further away then come closer to home again.
try changing the circle for arrival and departure to have a wider gap.
