Setup Guide

1. Physical Installation

The sensor is designed to be installed on top of the tank. Ensure there are no obstacles within the sensor's beam angle to prevent inaccurate readings.

1. Identify a suitable location on the top of your tank for mounting the sensor. This location should allow the sensor to be perpendicular to the liquid surface.
2. Drill a hole of appropriate size for the sensor's mounting nut.
3. Secure the sensor using the provided nut, ensuring a tight seal to maintain IP65 rating.
4. Connect the sensor to the controller and the power adapter.

2. App Setup and Connection (Tuya Smart Life APP)

The sensor requires a 2.4G Wi-Fi signal to connect to your router. The Wi-Fi range is approximately 30m without obstacles.

1. Download the "Tuya Smart" or "Smart Life" app from your mobile device's app store (iOS App Store or Google Play Store).
2. Register or log in to your account.
3. Add the device by following the in-app instructions. Typically, this involves selecting "Add Device" or the "+" icon, then choosing the appropriate sensor category (e.g., "Sensor" or "Water Detector").
4. Ensure your phone is connected to a 2.4GHz Wi-Fi network.
5. Follow the app's prompts to put the sensor into pairing mode (refer to the sensor's specific pairing button/indicator if available).
6. Enter your Wi-Fi network password when prompted.
7. Once connected, the sensor will appear in your app, and you can begin monitoring.

2. Setting Alerts

The app allows you to customize alert thresholds for full and low liquid levels. You will receive message alerts on your smartphone when these thresholds are met.

• Navigate to the sensor's settings within the app.
• Locate the "Alarm Level" or "Notification Settings" option.
• Set your desired percentage or depth for both high and low level alerts.
• Save the settings.

3. Multi-Tank Monitoring

The Tuya Smart Life APP supports monitoring multiple ME201WC sensors. You can add up to 10 sensors to a single app account, allowing centralized management of various tanks.

• Repeat the "App Setup and Connection" steps for each additional sensor.
• Each sensor will appear as a separate device in your app's device list.
• You can rename each sensor in the app settings for easy identification (e.g., "Main Water Tank", "Rainwater Barrel").

Maintenance

The MORAYELEC ME201WC sensor is designed for low maintenance. Follow these guidelines to ensure optimal performance:

• Cleaning: Periodically inspect the sensor's surface for dirt, dust, or debris. Clean with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Obstruction Check: Regularly check the area directly below the sensor inside the tank for any new obstructions (e.g., floating debris, sediment buildup) that could interfere with the ultrasonic beam.
• Firmware Updates: Check the Tuya Smart Life APP periodically for any available firmware updates for the sensor. Install updates as recommended to ensure the latest features and bug fixes.
• Power Supply: Ensure the power adapter is securely connected and free from damage.
