Take your phone to mailbox location and test WiFi signal strength. Many mailboxes are at property edges with weak WiFi coverage. Consider WiFi extender or cellular-based sensor if signal poor.
Verify App Notification Settings
Check smartphone notification settings for the mailbox app. Ensure notifications enabled push notifications allowed and Do Not Disturb not blocking alerts. Test by manually triggering sensor if possible.
Recalibrate Sensor Position
Follow manufacturer instructions to recalibrate sensor for your specific mailbox door type. Sensor must be positioned to reliably detect door opening while avoiding false triggers from wind or vibration.
Clean Sensor and Test Operation
Clean sensor housing and contacts with dry cloth removing dirt moisture and debris. Test sensor by opening mailbox door and checking for immediate response in app or LED indicator on sensor unit.
Quick Solutions
Still having issues? This is usually the deeper cause below.
Notification delays almost always return after a major iOS or Android update — background app refresh gets reset to restricted on every major OS version.
Position sensors away from direct sunlight and moisture. Consider cellular-connected sensors for mailboxes beyond reliable WiFi range.
Notification delays over 2 minutes are almost never the device's fault — background app restrictions quietly re-enable themselves after every OS update.
