- Sensor Life: The sensor probes have a lifespan of approximately 10 years.
- Cleaning: Periodically inspect the device and its probes for any dirt or debris. Clean with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.

6. Troubleshooting
- Device not connecting to Wi-Fi: Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz networks. Verify your Wi-Fi password is correct and the device is within range of your router. Follow the app pairing instructions carefully.
- No remote notifications: Verify the device is successfully connected to your 2.4GHz Wi-Fi network and the app is properly configured for notifications. Check your phone's notification settings to ensure the app has permission to send alerts.
- Alarm not loud enough: The device features a 75dB alarm. Ensure it is placed in an area where the sound can be heard. Consider placing multiple detectors in large or noisy areas.
- Sensor sensitivity issues: If the sensor does not detect water at very low levels, ensure the two bottom probes are making proper contact with the surface. Ensure there is no debris obstructing the probes.
