What to check first when home occupancy stays stuck on “someone is home” after everyone left
Technician
I do not want you changing every automation at once. The best first step is to find out whether this is a real sensor reading, a phone location issue, or a delayed home/away status in the app.
When did it start, and what type of system is deciding that someone is home: a dedicated presence sensor, a smart hub, phone geofencing, or a mix of those?
Technician
Two things matter first:
1) Is it always the same person shown as home?
2) Did anything change recently, like a phone update, app permission change, router change, or battery-saving setting?
Technician
Let’s separate the sources of “home” status:
• Does the room presence sensor itself still show motion or occupancy after you leave?
• Or is the house marked occupied only because that one phone never fully changes to away?
Technician
Trust moment: I would not delete and rebuild the whole presence setup yet. That often creates more confusion and hides the original cause.
When she leaves home, does her phone disconnect from Wi-Fi right away, or does the app still show it on the home network for a while?
Technician
Another simple check: after she leaves, does the map location in the phone app update correctly, but the person entity still stays home? Or is the location itself stale too?
Technician
Let’s check the safe basics before touching automations:
1) Is location access set to Always, or only While Using?
2) Is precise location allowed?
3) Does low power mode stay on most of the day?
Technician
I also want to rule out a misleading network clue: does the status usually get stuck only when she leaves quickly, like driving away, or even when she walks out and stays nearby for a few minutes?
Technician
Let’s not assume it is only the phone, though. Do you use any Bluetooth beacons, router-based trackers, or another app that also feeds presence into Home Assistant?
Technician
Trust moment: do not change both the router integration and the phone settings at the same time. One change at a time will tell you which source is really keeping the home status stuck.
In your history view, do you see the person entity stay home first and then the router tracker finally drop later, or is it the phone app location that lags first?
Technician
The safest next step is to review permissions and background behavior on that phone, then compare one leave-home test with careful notes. If the phone location updates cleanly, you can see whether the router tracker is still adding extra delay or whether the person logic itself needs review.
Quick answer: the accepted fix
Accepted first approach when a presence sensor keeps saying someone is home after everyone already left:
• Separate room occupancy from person tracking to confirm whether the problem is a sensor reading or a delayed home/away source
• Check recent changes such as phone updates, low power mode, background app limits, or location permission changes
• Compare Wi-Fi presence, app location, and person entity history to see which source lags first
• Change only one tracking source at a time so you can tell whether the false home status comes from the phone, router, or combined logic
• Keep one short leave-home test with notes instead of rebuilding all automations at once
Why home occupancy can stay stuck after everyone leaves
False “someone is home” status often comes from delayed phone location updates, Wi-Fi presence that clears late, or combined person logic that waits for more than one tracker to agree. This can become more noticeable after a phone update, battery-saving changes, or app permission changes. A room sensor may be working normally while the home status is still wrong.
What to check first without breaking your automations
Start with simple checks: which person stays home, whether the room sensor clears normally, and whether the app map or router tracker lags after leaving. Review location permissions, precise location, and background behavior on the affected phone before changing the whole setup. Small controlled tests give better answers than resetting everything at once.
Tip: don’t rebuild presence tracking until you know which source is stuck
A wrong home status is often one delayed tracker, not a fully broken system.
If the person entity stays home but the room sensor already cleared, the problem is usually in phone location, Wi-Fi presence, or the logic that combines them. A careful history check often shows which source lags first. That saves time and avoids creating new automation problems.

Getting Started Is Easy
Low-risk diagnosis first
Focus on safe checks (Ethernet comparison, Wi-Fi re-join, and roaming/security review) before resets or major network changes.
Identify what changed
Updates on the TV or router can change Wi-Fi behavior. Notes on timing and symptoms help you isolate the real trigger.
Avoid “random fixes”
Changing one variable at a time prevents new problems and makes it clear which step improved stability.
FAQ
Why does my presence sensor say someone is home when nobody is?
This often happens when phone location, Wi-Fi presence, or person logic updates late. The house can stay marked occupied even after everyone leaves. A room sensor may not be the real problem.
Did this happen after a phone update or settings change?
It can. App permissions, precise location, and low power mode can all affect home and away tracking. This is especially common after phone updates or battery-saving changes.
Is this a sensor issue or a tracking issue?
It depends on which source stays active. If room occupancy clears but one person still shows home, the issue is usually tracking rather than the sensor itself. History logs help show which source is lagging.
Can this be checked safely at home?
Yes. Start by comparing the room sensor, person entity, and phone location history after a simple leave-home test. Make one change at a time so you can see what really affects the result.
