Aqara Water Leak Sensor T1 – Smart sensor for detecting water leaks
The Aqara Water Leak Sensor T1 detects water leaks or flooding and monitors their status in real time. When a leak is detected, it instantly sends notifications through the app and can trigger automations in your smart home.
Key features:
Audible alerts and notifications via the hub:
When the water level reaches 0,5 mm, the sensor triggers an audible alert through the Aqara hub and sends a notification to your phone.
IP67 water and dust resistance:
The sensor is fully protected against dust and water, making it ideal for use in damp or dirty environments (bathroom, kitchen, basement).
Elegant design that fits anywhere:
Thanks to its compact design, it can be placed in any corner of the house. The detection area can be extended by connecting external wires to the probe screws.
Extensive compatibility:
Once connected to an Aqara hub, the sensor can be integrated with platforms such as Apple Home (with critical alerts), Samsung SmartThings and Yandex Smart Home.
Smart automations with Aqara Home:
You can create scenes such as: if a leak is detected, the sensor will command an Aqara smart plug to shut off a water solenoid valve.*
Advanced technology:
The housing is made of anti-UV material, which prevents discolouration over time. It uses very little energy – one battery can last over 2 years under normal conditions.
OTA update support:
Unlike older sensors, the T1 series supports wireless firmware updates, improving stability and functionality.
*The solenoid valve scene requires a mains-powered solenoid valve and an Aqara smart plug.
