Using a FRITZ!DECT smart switch

Using a FRITZ!DECT smart switch in the home network

The FRITZ!DECT smart switch, for example FRITZ!DECT 440, is integrated into your home network via an encrypted DECT connection (DECT ULE). With the smart switch you can operate smart plugs, for example FRITZ!DECT 200, radiator controls, for example FRITZ!DECT 302, and LED lights FRITZ!DECT 500. You can either switch smart home devices individually or together as a group. For example, you can attach the smart switch to an easily accessible location to conveniently operate smart plugs that are difficult to reach. Or you can simply push a button to activate the desired heating profile that you saved as a template or a scene.
