Product Info

Description

Compact, sturdy and smart, the Water Leak Sensor T1 detects even the slightest moisture – as little as 0.5 mm – and immediately alerts you via the Aqara Home app or hub alarm, helping prevent costly water damage. Its IP67 rating ensures reliable performance in humid, dusty environments.


Powered by a single CR2032 battery with up to two years' life and low-battery warnings, this sensor offers hassle-free, long-lasting protection. It uses Zigbee 3.0 for secure, low-power wireless connection—just pair it with your Aqara hub for seamless integration into Apple HomeKit, Google Assistant, Amazon Alexa, SmartThings, IFTTT and more.


With its sleek, compact design, it's easy to place anywhere—from under sinks to laundry rooms—offering reliable water-leak monitoring at every critical spot.


Key Features

  • Instant Alerts for Peace of Mind: When water reaches just 0.5 mm, the Aqara Water Leak Sensor instantly triggers the Hub alarm and sends a push notification to your phone.
  • Reliable in Any Environment: With an IP67 dustproof and waterproof rating, the sensor is built to perform in humid or dusty spaces.
  • Compact, Elegant Design: Its sleek form allows it to fit discreetly anywhere you need protection.
  • Smart Control with Apple Home: Seamlessly works with other HomeKit-enabled devices via the Apple Home app, making everyday life easier.
  • Aqara Home Automations: Link with other Aqara products for tailored protection—for example, automatically shutting off a water valve through a Smart Plug the moment a leak is detected.*
  • Energy-Efficient & Durable: Made with anti-UV materials to resist discolouration, while its long-lasting battery provides up to two years of reliable use.
  • OTA Updates: Supports over-the-air updates, improving stability and functionality

Note:
* This scene requires a solenoid water valve and an Aqara Smart Plug.
