Maintenance
To ensure the longevity and accurate performance of your soil moisture meter, please observe the following:
- Batteries: Do not mix old, new, or different types of batteries. Replace all batteries at the same time with fresh ones of the same type.
- Waterproof Seal: Always ensure the battery compartment screws are tightened securely after installing or replacing batteries to maintain the IPX5 waterproof rating.
- Temperature: Keep the sensor away from freezing temperatures, as extreme cold can affect its performance and lifespan.
- Installation: Always follow the installation guide to properly install the sensor, ensuring the 'BEST' mark is buried in the soil for accurate readings.
- Cleaning: Periodically clean the sensor probe to remove any soil buildup that might affect accuracy. Use a soft cloth and avoid harsh chemicals.

Troubleshooting
If you encounter issues with your Wifi Smart Soil Moisture Meter, please refer to the following common problems and solutions:
- No Data in App / Sensor Offline:
- Check if the batteries are correctly installed and have sufficient charge. Replace if necessary.
- Ensure the sensor is within range of your Garden Control Hub and that the Hub is connected to a stable 2.4 GHz Wi-Fi network.
- Verify that the HomGar APP is updated to the latest version.
- Restart the sensor (by removing and reinserting batteries) and the HomGar APP.
- Confirm that the sensor is compatible with your specific HomGar APP series water timer/hub (refer to compatibility notes in Setup section).
- Inaccurate Readings:
- Ensure the sensor is properly installed with the "BEST" mark buried in the soil. Poor contact with soil can lead to inaccurate moisture readings.
- Clean the sensor probe to remove any dirt or debris that might be interfering with measurements.
- Calibrate the sensor if the app provides such an option (check app settings).
- Consider the soil type; very sandy or rocky soils might affect moisture readings differently.
- Cannot Connect to Wi-Fi:
- Ensure your Wi-Fi network is 2.4 GHz. The device does not support 5 GHz networks.
- Check the distance between the sensor/hub and your Wi-Fi router. Reduce obstacles if possible.
- Verify your Wi-Fi password and network settings in the HomGar APP.
- Restart your Wi-Fi router.
