1. Product Overview
The Imou ZL1 ZigBee Smart Water Leak Sensor is designed to detect water leaks and alert you to potential flooding, helping to prevent water damage in your home or office. This compact and discreet sensor uses ZigBee technology for reliable wireless communication with your compatible smart home hub.

2. Setup Instructions
Follow these steps to set up your Imou ZL1 Smart Water Leak Sensor:
- Prepare Your Environment: Ensure you have a compatible ZigBee hub (e.g., Imou Smart Hub) and the Imou Life app installed on your smartphone. Make sure your Wi-Fi network is 2.4GHz.
- Insert Batteries: The sensor requires batteries (not included). Open the sensor's casing (refer to the diagram below for battery compartment location) and insert the required batteries, ensuring correct polarity.
- Open Imou Life App: Launch the Imou Life app on your smartphone and log in to your account.
- Add Device: Tap the '+' icon or 'Add Device' option in the app. Select 'Sensor' or 'Water Leak Sensor' from the device list.
- Pair with Hub: Follow the on-screen instructions to put your ZigBee hub into pairing mode. Then, activate the sensor's pairing mode (usually by pressing a button inside the battery compartment or on the device itself for a few seconds until an indicator light flashes).
- Confirm Connection: Once the sensor is detected and paired, the app will confirm the successful connection. You may be prompted to name the sensor and assign it to a specific room.
- Placement: Place the sensor on a flat surface in areas prone to water leaks, such as near water heaters, washing machines, sinks, or in basements. Ensure the contact points on the bottom of the sensor are facing downwards and can come into contact with water.

- Automations: Through the Imou Life app, you can set up smart automations, such as triggering an alarm siren (if connected to an Imou alarm system) or sending alerts to other family members when a leak is detected.
- Status Check: You can check the current status of your water leak sensor (e.g., battery level, last detection) at any time through the Imou Life app.
4. Maintenance
Regular maintenance ensures optimal performance of your water leak sensor:
- Battery Replacement: The sensor is battery-powered. When the battery level is low, you will receive a notification in the Imou Life app. Replace the batteries promptly to ensure continuous protection. Use the specified battery type (refer to the sensor's internal markings or packaging).
- Cleaning: Periodically clean the sensor's exterior and especially the water contact points with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Testing: It is recommended to periodically test the sensor by placing its contact points in a small amount of water to ensure it triggers an alert correctly.
