You can configure, control, and evaluate up to 100 smart home devices in the FRITZ! home network. To integrate them into the home network, the devices can be registered with the FRITZ!Box with internet access or an additional FRITZ!Smart Gateway or an additional FRITZ!Box as a Mesh Repeater.

A total of up to 50 of the following devices can be directly registered with a FRITZ!Box:

• max. 50 FRITZ! radiator controls (for example FRITZ!Smart Thermo 302)
• max. 50 FRITZ! smart switches and door/window contacts (for example FRITZ!Smart Control 440, FRITZ!Smart Control 350)
• max. 20 FRITZ! smart plugs and LED lights (for example FRITZ!Smart Energy 210, FRITZ!DECT 500)
• max. 30 devices from other manufacturers that support the DECT ULE/HAN FUN standard

  If more than 3 DECT cordless telephones (for example FRITZ!Fon) or DECT door intercom systems are registered with the FRITZ!Box, we recommend registering fewer than 30 HAN FUN devices since some functions may not work properly.

• max. 40 devices from other manufacturers that support the Zigbee standard and are compatible with FRITZ!Box models with Zigbee support
