BOSCH Contact II Door opening sensor 3 pcs White

Running in the house is a thing of the past: thanks to the Bosch Smart Home Door/Window Contact II, you can check with a single look at the application to see if a window or door is open or closed. If the condition changes, you can notify you with a push notification or widget - either at home or away. If the door/window detector detects window opening while the alarm system is active, it immediately triggers alarms. Once the alarm system is activated, it will be warned about vulnerabilities in the form of open doors or windows. In cooperation with smart radiator termostats, the heating automatically turns off when ventilated.
