5. Maintenance
5.1 Waterproofing
The Diivoo Water Flow Meter is rated IP55 waterproof, meaning it is protected against dust ingress and low-pressure water jets from any direction. While it can withstand splashes and light rain, avoid submerging the device in water.

5.3 Storage
When not in use for extended periods, especially during freezing temperatures, disconnect the meter from the water source, drain any remaining water, and store it in a dry, protected area to prevent damage.
6. Troubleshooting
If you encounter issues with your Diivoo WiFi Water Flow Meter, consider the following common solutions:
- No Display/Power: Check if the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
- Connectivity Issues (Hub/Meter): Ensure the WiFi Hub is powered on and within the 60-meter range of the meter. Verify your home WiFi network is 2.4GHz. Try restarting both the hub and your router. If the hub won't connect to WiFi, ensure correct network credentials are entered in the app.
- Inaccurate Readings: Ensure the meter is installed correctly and there are no leaks. Check and clean the metal filter for any blockages. Use the "Water Usage Correction" feature in the app to manually calibrate the device if needed.
- No Flow Detected: Ensure water pressure is adequate. This device is designed for pressurized systems and may not function correctly with gravity-fed drains, as noted by some users.
- App Not Responding: Close and reopen the Smart Life app. Ensure your smartphone has a stable internet connection.
If problems persist, please contact customer support for further assistance.
