Magnetic switch for monitoring windows and doors. It can be integrated as a door contact or window sensor into your own WiFi network via the free "Hama Smart Home" app. The status is displayed: door or window opened or closed. Easily add it through the existing Hama Smart Home Hub or the Hama heating control center. With your WiFi-connected devices, you can create groups or scenes, for example, in combination with a heating control system to immediately lower the temperature when windows are opened. The status can also be queried by voice through Amazon Alexa or Google Assistant. The switch features built-in tamper protection and sends push notifications for status changes or tampering attempts. It has low power consumption and is powered by two AAA batteries.

System requirements: Operating system: Android 6 and iOS 11.0 or higher.

Consumer notice: To integrate the smart door/window contact into the WiFi network, a Zigbee-capable smart home hub is required (not included), such as the Hama Smart Home Hub or the Hama heating control center.
