5. Setup and Installation
The sensor is designed for easy top-mount installation. Follow these steps for proper setup:
- Choose Installation Location: Select a suitable location on the top of your tank. Ensure the sensor has a clear line of sight to the liquid surface and is not obstructed by internal tank structures.
- Mount the Sensor: Use the included mounting nut and screws to securely attach the sensor unit to the top of the tank. Ensure a stable and level placement.
- Position the Probe: Lower the sensor probe into the tank. The probe should hang vertically and freely, without touching the tank walls or bottom, and should not be submerged in the liquid. The ultrasonic sensor measures the distance to the liquid surface.
- Connect Power: Connect the provided power adapter to the sensor unit and plug it into a standard power outlet.
- Download App: Download the Tuya Smart Life APP from your smartphone's app store (iOS or Android).
- Pair with App: Open the Tuya Smart Life APP, register or log in, and follow the in-app instructions to add a new device. Ensure your phone is connected to a 2.4GHz WiFi network during the pairing process. The sensor will connect to this network.
- Verify Connection: Once paired, the sensor's status should appear online in the app, and you should see initial liquid level readings.

6. Operating Instructions
Once installed and connected to the Tuya Smart Life APP, you can begin monitoring your tank's liquid levels.
- Accessing Data: Open the Tuya Smart Life APP on your smartphone. Select your MORAYELEC Water Level Sensor from the device list.
- Real-time Monitoring: The app will display the current liquid level ratio (percentage), liquid depth, and supply voltage. Data is updated in real-time.
- Historical Data: View historical liquid level data over various periods (day, month, year) to track consumption or changes.
- Setting Alarms: Navigate to the sensor's settings within the app to set custom alarm thresholds for low and full liquid levels. You will receive push notifications when these thresholds are met.
- Multi-Tank Monitoring: If you have multiple MORAYELEC sensors, you can monitor all of them from a single dashboard within the Tuya Smart Life APP.

- Firmware Updates: Check the Tuya Smart Life APP periodically for any available firmware updates for your sensor. Updates can improve performance and add new features.
8. Troubleshooting
If you encounter issues with your MORAYELEC Smart WiFi Water Level Sensor, refer to the following troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not connecting to WiFi | Incorrect WiFi password; Sensor too far from router; Router is 5GHz only; Network congestion. | Ensure correct 2.4GHz WiFi password. Move sensor closer to router. Check router settings for 2.4GHz band. Restart router. |
| No liquid level readings in app | Sensor not powered; Probe obstructed or incorrectly positioned; App not refreshed. | Check power connection. Ensure probe is hanging freely and not submerged. Refresh the app. Re-pair the device if necessary. |
| Inaccurate readings | Probe obstructed; Sensor not level; Interference from tank features; Condensation on sensor. | Clean probe. Ensure sensor is mounted level. Reposition sensor if internal tank structures cause interference. Ensure proper ventilation. |
| Alarms not triggering | Alarm thresholds not set; App notifications disabled; Sensor offline. | Set alarm thresholds in the Tuya Smart Life APP. Enable notifications for the app on your phone. Check sensor's online status. |
