FRITZ!Smart Control 350

Attach the FRITZ!Smart Control 350 to doors or windows and it immediately detects whether they're open or closed. As the trigger for controlling FRITZ!Smart products and compatible Zigbee devices, the magnetic door/window contact enables a wide range of smart home scenarios.

Perfectly integrated into the FRITZ! home network

The FRITZ!Smart Control 350 is optimized for use with a FRITZ!Box Together with the FRITZ! radiator controls, such as the FRITZ!Smart Thermo 302, the FRITZ!Smart Control 350 is an efficient way to save heating costs when you use it as an external window sensor. It is extremely easy to realize scenarios such as ‘When window open, then turn down heating’. All other FRITZ!Smart devices and compatible Zigbee devices can also be switched and controlled with the door/window contact, allowing a range of automated routines and application scenarios in your smart home.

Know what's happening

So you can see what's going on and for greater security, the status is displayed in real time in the FRITZ!App Smart Home, on the FRITZ!Fon, and in the FRITZ!Box user interface. For example, you can check at any time whether the roof window is really closed.

Easy to mount

Thanks to its compact and lightweight design, FRITZ!Smart Control 350 can be attached to almost any door or window frame. Many modern windows with Eurofold allow it to be installed 'invisibly' between the window frame and the window sash. Thanks to its discreet design, FRITZ!Smart Control 350 blends unobtrusively into any environment  .

Get creative

When you open your basement door, do you want the light to come on automatically and then turn off again after a few minutes? Would you like to know when your pet uses the cat/dog flap? Or would you like to be notified as soon as your letterbox flap is opened and you get new post? FRITZ!Smart Control 350 offers a wide range of practical uses.

In just a few minutes you'll have FRITZ!Smart Control 350 integrated into your home network: insert the batteries, press the Connect button on the FRITZ!Box, and the FRITZ!Smart Control 350 is registered. The individual settings are configured conveniently in the FRITZ!Box user interface.
