Product detailed description
🏠 Equip Your Home with a Smart Sensor
This sensor connects to your home Wi-Fi network via a hub, allowing you to receive instant notifications on your smartphone or other connected devices when a door or window is opened or closed.
Easily install the sensor on a window or door frame using 3M tape. It consists of two parts – as soon as the parts are separated, the sensor sends an alert to your mobile phone, as well as when the battery needs replacing. Connecting the sensor to smart home elements, such as a security camera, comes as a matter of course, giving you the ability to set up automated scenes.

The sensor can be controlled via the Meross app and is compatible with Apple HomeKit, Amazon Alexa, Google Home, and Samsung SmartThings. Add it to your daily ecosystem for even more control options. Voice control support (HomePod/Siri) makes management easy even remotely.
Note: A Meross HomeKit Hub is required for proper operation and is not included in the package.
