Details
Battery-operated sensor that sticks easily to any door, giving you real-time status updates – even when you’re not home.
So Useful. So Small.
A Tiny, Smart Guardian
Stick one of these sensors to any of your doors and windows, and seamlessly receive real-time updates and status in your Aqara or Apple Home apps. With the Aqara Door and Window Sensor, you can configure alarms or notifications to be triggered on the door opening or closing.
You can also set reminders, such as a notification being sent when a door has been left open for more than 10 minutes.
As part of a smart home system, these sensors can also trigger other smart devices, such as lights turning on when the door is opened.
- An Aqara Smart Zigbee Hub is required.

Built to be Invisible

The Aqara Door and Window Sensor is miniscule, about half the size of a lighter. It comes with an adhesive pad, so you can stick it anywhere on your door and door frame. Powered with a battery that gives it up to two full years of charge, this sensor requires no wires or concealing.
Compatible with Apple HomeKit and Amazon Alexa
The Aqara Door and Window Sensor is compatible with Apple HomeKit, Amazon Alexa, and the Aqara App – broadening the scope of the sensor in applications across different platforms.
