Direct answer
Intermittent behavior is diagnosed by the trigger—movement, heat, load, sleep, distance or time—not by repeating broad resets. For smart-home presence and geofence, first check which household member triggered the event and test location permission/background access.
What this covers
- smart-home presence and geofence with this exact failure state
- Diagnosis across phone permission/background state versus account membership and overlapping occupants
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleLog the trigger, duration, indicator state and whether physical movement or temperature changes it. Expected behavior: change home/away state only for authorized household phones with location available.
Isolate the component boundary
ReversibleCheck which household member triggered the event and test location permission/background access. Hold every variable constant except one cable, location, load or host at a time. Boundary to separate: phone permission/background state versus account membership and overlapping occupants.
Correct only the proven cause
ReversibleCorrect household membership, precise location and battery restriction. Replace or reconfigure the one variable that reproduces the drop.
Verify and stop safely
ReversibleRun beyond the previous failure time and through sleep, movement or load once. Do not use geofence alone for security, fire or dependent-care decisions.

Exact questions
Common follow-ups
What should I check first when smart-home presence and geofence has this problem?+
Check which household member triggered the event and test location permission/background access.
Why not factory-reset immediately?+
The useful boundary is phone permission/background state versus account membership and overlapping occupants. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not use geofence alone for security, fire or dependent-care decisions.
