About this item

  • [Notes] An Aqara Hub is required and sold separately. Not compatible with hubs from other brands. Requires a secure 2.4GHz Wi-Fi connection for Hub M2, M1S, E1, M1S Gen2, G2H Pro, and G2H; or 2.4/5GHz Wi-Fi for Camera Hub G3. (Hub M2 also supports wired Ethernet via RJ45.). Pair the Zigbee Water Leak Sensor with an Aqara Hub before connecting to Apple HomeKit, Google Home, or Alexa. For a stable Zigbee connection, ensure the sensor is placed within 10 meters(33 ft) of the Aqara Hub.
  • [Proximity] To ensure a stable connection, keep the Aqara Water Leak Sensor within 400 inches (approximately 10 meters) of the Aqara Zigbee Hub, and place the hub within the same range of your Wi-Fi router. Ensure both are connected to the same local area network (LAN). Zigbee2MQTT and comparable third-party USB dongles are not officially supported by Aqara. Full product functionality may be limited or unavailable.
  • [Drip and Leak Detection] Equipped with highly sensitive probes that detect water levels as low as 0.5 mm (approximately 0.02 inch), this water leak detector instantly sends alerts to your phone and triggers the local alarm on the Aqara Hub whenever a leak is detected.
  • [Home automation] The water leak detectors for home can control and trigger other Aqara devices when water is detected, allowing you to take prompt action to keep your home safe. *Requires Aqara Hub, not third-party hub.
  • [Wireless & Compact Design] No wiring or screws are required. The small, sleek design allows you to place the Zigbee leak sensor on any flat surface in your kitchen, basement, laundry room, or any area you want to monitor. Recommended placements include near or under toilets, water heaters, washing machines, dishwashers, sinks, fish tanks, sump pumps, or any area prone to leaks.
  • [Industry-Leading Quality] Durable IP67 water-proof housing with rust-proof exterior coating. Please remove the battery tab before use. If the device does not work, check the battery level. For any questions, please feel free to contact us.

Pros & Cons Analysis

Product Pros

  • High-Precision Micro-Leak Detection

    Capable of detecting water leaks as small as 0.5mm, far exceeding general standards, enabling early detection of initial leaks to minimize potential damage.

  • Deep Smart Ecosystem Integration

    While requiring an Aqara Hub, it seamlessly integrates with Apple HomeKit, Google Smart Home, and supports IFTTT automations, offering strong expandability.

  • Robust, Durable, High Protection

    Features an IP67 waterproof housing with an anti-rust coating, ensuring long-term stable operation even in damp or harsh environments.

  • Wireless, Compact, Flexible Deployment

    Wireless and compact design requires no wiring or screws, allowing for easy placement in tight, concealed areas like under sinks or next to washing machines.

  • Multi-Pack Offers High Value

    Offered in a pack of 3 sensors, providing a more cost-effective overall solution for multi-area monitoring compared to purchasing single units.

Product Cons

  • Mandatory Dependency on Proprietary Hub

    Must be used with an Aqara Hub and is incompatible with other brands' Zigbee Hubs, significantly increasing initial user cost and creating system limitations.

  • Questionable Connection Stability

    User feedback indicates intermittent disconnections and unstable connectivity, potentially affecting alarm timeliness and system reliability.

  • Partial Function Reliability Concerns

    Customer reviews show inconsistent performance in water detection and battery life, with some units ceasing to work or failing to detect leaks after several months.

  • Useless Built-in Temperature Sensor

    The data from the built-in temperature sensor is inaccurate, rendering it unsuitable for environmental reference, while adding unnecessary product cost and functional redundancy.

  • Local Alarm Dependency on Hub

    The sensor lacks an independent audible alarm; local alerts rely entirely on the Aqara Hub, limiting alarm functionality if the Hub fails.
