Step by step
Verify global location permissions
Navigate to Settings > Privacy & Security > Location Services. Ensure the toggle for Location Services is green and verify that your specific smart home app is set to Always allow access to your precise location.
Note: Precise Location must be toggled on for accurate geofencing triggers.Reset the home occupancy status
Open your primary home automation controller app. Manually trigger an 'Away' scene, wait ten seconds, then trigger an 'Arrive' scene to force a state update between your mobile device and the hub.
Validate router network isolation
Confirm that your smart home hub and your smartphone are connected to the same VLAN or subnet. If your network uses an isolated guest network for IoT devices, your phone will fail to communicate occupancy changes to the hub.
Note: Ensure mDNS or Bonjour is enabled on your router settings.Refresh hub firmware cache
Power cycle your smart home hub by disconnecting the power cable for 30 seconds. Upon reboot, the hub will re-establish handshake protocols with all associated presence sensors and connected mobile devices.
Adjust geofence radius sensitivity
If automations trigger too early or late, access the Automation tab in your app and select the Arrive trigger. Expand the radius setting for your home location to compensate for GPS drift or signal latency in high-density environments.
Note: A larger radius is more reliable for residential areas with poor cellular signal.
