Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
Leak sensor reliability depends heavily on environment and probe hygiene.
Notification delays over 2 minutes are almost never the device's fault — background app restrictions quietly re-enable themselves after every OS update.
