5. Setup Guide
5.1 Important Requirement: Maxcio Tuya Zigbee Gateway
The Maxcio Water Leak Sensor requires a Maxcio Tuya Zigbee Gateway (sold separately) to function and send app notifications. Ensure your gateway is connected to a 2.4 GHz Wi-Fi network (5 GHz is not supported). One gateway can connect up to 22 devices.

5.2 Battery Installation
- Locate the battery compartment on the underside of the sensor.
- Twist the cover counter-clockwise to open.
- Insert the CR2032 battery, ensuring correct polarity (+/-).
- Replace the cover and twist clockwise to secure.
5.3 App Download and Gateway Pairing
- Download the "Maxcio SmartLife" app from your smartphone's app store (iOS or Android).
- Register or log in to your account.
- Follow the in-app instructions to add and pair your Maxcio Tuya Zigbee Gateway.
5.4 Sensor Pairing
- Ensure your Zigbee Gateway is online and in pairing mode (refer to gateway manual if needed).
- In the Maxcio SmartLife app, select your Zigbee Gateway and choose to add a new sub-device.
- Press and hold the reset button on the water leak sensor for 5-10 seconds until the LED indicator flashes, indicating pairing mode.
- The app will detect the sensor. Confirm the pairing.
- Once paired, you can rename the sensor for easy identification (e.g., "Kitchen Sink Sensor").

5.5 Sensor Placement
Place the sensor directly on a flat surface in areas prone to water leaks. The two metal probes on the bottom of the sensor must come into contact with water for detection.
- Under sinks (kitchen, bathroom)
- Near washing machines or dishwashers
- In basements or utility rooms
- Near water heaters or sump pumps
- Underneath refrigerators with ice makers

6. Operating Instructions
6.1 Water Leak Detection
When the sensor's probes detect water at a level of 0.5mm or higher, it will trigger an alarm. The sensor's LED will flash red, and it will send a signal to the connected Zigbee Gateway.

6.2 App Notifications
Upon detection, the Zigbee Gateway will forward the alert to your Maxcio SmartLife app, providing real-time notifications to your smartphone. This allows you to monitor your home for leaks remotely.

6.3 Home Automation
You can configure automation rules within the Maxcio SmartLife app to link the water leak sensor with other Tuya-compatible smart devices. For example, if a leak is detected near a washing machine, a smart plug connected to the washing machine can be automatically switched off.

7. Maintenance
7.1 Battery Replacement
The sensor uses a CR2032 battery. When the battery is low, you will receive a low battery notification in the Maxcio SmartLife app. Replace the battery by following the steps in Section 5.2.
7.2 Cleaning
Wipe the sensor with a dry, soft cloth. Do not use abrasive cleaners or immerse the entire device in water (only the probes are designed for water contact).
7.3 Connectivity Check
Periodically check the sensor's status in the Maxcio SmartLife app to ensure it is online and communicating with the gateway.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No app notifications when water is detected. | Sensor not paired with gateway; Gateway offline; App notifications disabled; Sensor battery low. | Ensure sensor is paired (Section 5.4). Check gateway's internet connection. Enable notifications in app settings. Replace battery (Section 7.1). |
| Sensor appears offline in the app. | Sensor too far from gateway; Gateway offline; Sensor battery low. | Move sensor closer to the gateway (recommended distance 7-10 meters). Check gateway's status. Replace battery (Section 7.1). |
| Sensor not detecting water. | Probes not in contact with water; Insufficient water level; Sensor damaged. | Ensure probes are fully in contact with water. Water level must be at least 0.5mm. Contact support if suspected damage. |
| Cannot pair sensor with gateway. | Gateway not in pairing mode; Sensor not in pairing mode; Interference. | Put gateway into pairing mode. Press and hold sensor reset button until LED flashes. Reduce distance between sensor and gateway. |
