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 control smart plugs, for example FRITZ!DECT 200, radiator controls, for example FRITZ!DECT 301, and with FRITZ!OS 7.20 or later also LED lights FRITZ!DECT 500. You can either switch smart home devices individually or together as a group, and you can also use the smart switch to activate templates. For example, you can attach the smart switch to an easily accessible location in order to conveniently use outlets that are difficult to reach. Or you can simply push a button to activate the desired heating profile that you saved as a template.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

Requirements / Restrictions
