Setup

1. Battery Installation

The sensor requires one CR2-3V battery (not included). To install:

1. Locate the battery compartment on the bottom of the sensor.
2. Twist the cover counter-clockwise to open.
3. Insert the CR2-3V battery, ensuring correct polarity (+/-).

2. Download and install the application.
3. Register a new account or log in if you already have one.

3. Connecting to Wi-Fi

Ensure your Wi-Fi network is 2.4GHz. The sensor does not support 5GHz networks.

4. Placement Recommendations

Install the sensor in locations prone to water leaks or floods. Common areas include:

• Near washing machines or dishwashers.
• Under sinks in kitchens or bathrooms.
• In basements or utility rooms.
• Near water heaters or sump pumps.
• Anywhere pipes or water lines are present.

Ensure the probe cable is positioned so that the metal sensing probe will come into contact with water first in the event of a leak.

Operating Instructions

Once installed and connected, the sensor operates automatically.

• Water Detection: When the metal sensing probe detects water (i.e., it becomes submerged), the sensor will immediately trigger an alarm.
• Local Alarm: The sensor will emit an audible beep to alert you to the presence of water.
• App Notification: Simultaneously, a push notification will be sent to your smartphone via the "TuyaSmart" or "Smart Life" app, informing you of the water leak. This allows for remote monitoring and immediate action.
• Status Monitoring: You can check the current status of the sensor (e.g., battery level, connection status) at any time through the mobile application.

Maintenance

Battery Replacement

The sensor's battery life is approximately 1 year (with 15 alerts/day) or 2 years (with 7 alerts/day). The app will notify you when the battery level is low. To replace the battery, follow the steps outlined in the "Battery Installation" section under Setup.
