FRITZ!DECT 350 – the door/window sensor for your FRITZ! Smart Home

The magnetic FRITZ!DECT 350 door/window contact detects whether doors or windows are opened or closed. The sensor is perfectly integrated into the FRITZ! Smart Home and can be used to trigger actions – for example, for the window-open detection of your FRITZ! smart radiator control. You can also automate actions with the door/window contact.
