The smart window handle is easy to add to many smart home systems that support the new Matter communication standard. This means that anyone can experience that feeling of security and comfort, and control it however they like using an app or voice assistant.

Matter simplifies the compatibility and communication between devices from different producers. Making smart homes as straightforward as possible for everyone: that's the idea behind Matter and what drives SIEGENIA when it comes to developing smart products.

The handle that adds a touch of magic to windows.

The smart window handle is the innovative upgrade from manually lockable window handles: security and convenience, magically combined in a single product. This eliminates the security risk associated with keys becoming stuck, as well as the inconvenience of searching for keys. Thanks to its smart functionality, windows can do more – from customised control to effortless integration in smart home scenarios. And it's just as easy to install on standard timber and PVC windows as a conventional window handle.

You can also monitor and control the status of your window handles at any time using the remote function, even when you're away from home. Smart technology that makes you feel good.

Create your own smart home scenarios

The window handle can communicate with Matter-enabled smart home devices from other producers. This means that scenarios can be created via the app and customised to suit your own needs. To save energy, for example: the heating or air-conditioning can be turned down automatically as soon as a window is opened.

A central control unit that supports both Matter and Thread is required in order for the smart window handle to be used with a smartphone or home controller. To integrate the smart window handle into your smart home, simply scan the Matter code on the device. Once you've done that, it is easy to set up and access from your smart home app.
