Using FRITZ!DECT 350
FRITZ!DECT 350 is a magnetic door/window contact for use in your FRITZ!Box home network. Due to its small size, the sensor can mounted so that it is hidden between the window frame and the sash in many windows with Eurofold. The door/window contact detects immediately when doors or windows are opened, closed, or tilted and for additional security, it signals the status, for instance, open/closed windows, in the FRITZ!App Smart Home, on the FRITZ!Fon, and in the user interface of the FRITZ!Box.
The door/window contact can switch smart plugs and LED lights, for example FRITZ!DECT 200, FRITZ!DECT 500, and regulate the radiator control FRITZ!DECT 302. Additionally, FRITZ!DECT 350 also switches compatible Zigbee devices from other manufacturers. It can also activate templates and scenarios and trigger routines. This makes it extremely easy to realize scenarios such as "If door open, then light on".
