The Aqara Valve Controller T1 is a practical solution that makes your home's water or gas valves smart. Compatible with lever or butterfly valves, it works seamlessly with pipe diameters DN15, DN20, and DN25 (1/2, 3/4, and 1 inch). Using the Zigbee wireless protocol, when paired with a compatible Aqara hub, it integrates with popular ecosystems such as Apple Home, Amazon Alexa, and Google Home via Matter over Bridge support, offering a centralized smart home experience. Its key technical advantage is a long battery life of up to 2 years with four AA batteries, allowing easy installation on your existing valve without extra wiring. When integrated with a water leak sensor, the device automatically closes the valve within 5 to 20 seconds upon leak detection, providing effective protection against potential flooding. It offers three control options: manual button, Aqara Home app, and timer. Ideal for daily use, especially when you are away from home, it can automatically shut off the main valve if a water leak is detected in the bathroom or kitchen. You can also use it to open and close your garden sprinkler system at a set time each morning. Additionally, by integrating with a presence sensor, you can create advanced automations such as closing the valve when no one is home. Important note: the device is not waterproof and should not be used on outdoor valves.
