What Is the Water Leak Sensor and What Does It Do?
The Aqara Water Leak Sensor is a compact, battery-powered Zigbee device designed to detect water presence or leaks. It solves the problem of undetected water damage by alerting users through connected hubs when water levels reach 0.5 mm or more via probe conductivity. Commonly used in kitchens, bathrooms, basements, or near appliances, it triggers alarms, notifications, or automations like shutting off valves. The sensor features an IP67 dustproof and waterproof rating for humid environments and offers up to 2 years of battery life. Placement is flexible on flat surfaces, with an optional wire extension for probes.
What Does the Water Leak Sensor Work With? (Compatibility and Integrations)
The sensor requires an Aqara Hub for operation, as it communicates solely via Zigbee protocol and cannot function independently. Native integrations occur through Aqara hubs with ecosystems like Apple HomeKit, Google Assistant, Amazon Alexa, Samsung SmartThings, and Yandex Smart Home. Voice assistant support works via these hubs, with HomeKit offering critical alerts after binding. Matter compatibility is available through Aqara gateways with Matter bridge support, though it demands specific hub firmware like Matter 1.3. Behavior is local within Zigbee networks but relies on the cloud for some app notifications; Home Assistant uses bridged Zigbee integrations without a native Aqara hub. Limitations include mandatory hub setup and no direct Wi-Fi or standalone use.
Does the Water Leak Sensor Work With Home Assistant?
Yes, through Zigbee integrations like ZHA or Zigbee2MQTT with a compatible Zigbee coordinator. It works locally once paired, exposing water leak detection status, battery level, and link quality. Functionality supports automations for notifications or device triggers. No Aqara hub is needed with these integrations. A HomeKit variant may exist, but the standard Zigbee model pairs reliably.
