Using a smart home device from another manufacturer in the home network

You can also register smart home devices from other manufacturers with your FRITZ!Box, for example motion detectors, door/window contacts, smart switches, smart plugs, roller shutter motors.

The connection between the smart home device and the FRITZ!Box is established using the DECT ULE protocol HAN FUN. This allows you to register all smart home devices with the FRITZ!Box that the manufacturer has declared to be compatible with DECT ULE/HAN FUN.

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

Requirements / Restrictions

  • Actuators from other manufacturers, for example smart plugs, cannot be registered with the FRITZ!Box.
  • Radiator controllers, for example FRITZ!DECT 302, cannot be switched via smart home devices from other manufacturers.

1 Configuring the FRITZ!Box

In the factory settings, the FRITZ!Box is configured for use as an access point. If you changed the FRITZ!Box's DECT settings, configure the following settings:
