Product Description:

The SONOFF Zigbee Water Leak Sensor (SNZB-WL) is a compact and reliable sensor designed to detect water leaks early, helping prevent damage and ensuring peace of mind. It operates with Zigbee 3.0 technology, allowing for easy integration with Zigbee hubs and smart home setups. When water is detected, it sends an instant alert to your Zigbee gateway, which can notify you through a connected app or automation system.

Key Features:

• Zigbee 3.0 Compatibility: Works seamlessly with Zigbee hubs and devices.
• Early Leak Detection: Detects water leakage and sends real-time alerts.
• Smart Alerts: Send notifications to your smartphone when a leak is detected.
• Long Battery Life: Equipped with a durable battery (CR2032 coin battery) with a long lifespan.
• Compact Design: Small and discreet, making it suitable for tight spaces, such as under sinks or in basements.
• Real-Time Monitoring: Can be used to monitor potential leak areas continuously.
• Easy to Integrate: Connects to the Zigbee ecosystem, including smart hubs like SONOFF Zigbee Bridge Ultra or compatible systems like SmartThings.
• Low Power Consumption: Efficient power use for long-lasting battery life.

How It Works:

1. Water Detection: When water touches the sensor’s metal probes, it detects the moisture and sends an alert.
2. Smart Integration: The device integrates with Zigbee hubs (like the SONOFF Zigbee Bridge Ultra), which relay alerts to your smartphone or smart home system.
3. Automations: Trigger other devices, like a smart valve, to close water supply lines or send further notifications.

Use Cases:

• Under Sinks: Detect leaks that could cause flooding or water damage in the kitchen or bathroom.
• Basements: Monitor areas prone to flooding, particularly in storm-prone regions.
• Washing Machines: Ensure that water leakage from appliances doesn’t cause damage.
• Water Heaters: Detect leaks from water heaters before they lead to major water damage.

Benefits:

• Protects Property: Minimizes water damage risk by detecting leaks early.
• Low Maintenance: Battery-powered with long battery life, requiring minimal upkeep.
• Peace of Mind: Constant monitoring and alerts ensure that you are informed whenever a leak occurs.
• Affordable Protection: A cost-effective way to safeguard your home from costly water damage.

Installation Instructions:

1. Place the Sensor: Position the sensor in areas prone to leaks (e.g., under sinks, near water heaters, or washing machines).
2. Set Up with Zigbee Hub: Pair the device with a compatible Zigbee hub via the Zigbee network (e.g., SONOFF Zigbee Bridge Ultra).
3. Activate Alerts: Enable notifications in the associated app (e.g., eWeLink, SmartThings) to receive instant water leak alerts.
4. Check Battery: Ensure the sensor’s CR2032 battery is working, and replace it when necessary (typically every 1-2 years).
