BOSCH Contact II plus door and window opening sensor white

Running in the house is a thing of the past: thanks to the Smart Home Door/Window Contact II plus, you can check with a single glance in the application to see if a window or door is open or closed. If the condition changes, you can inform you with a push notification or widget-no matter whether it is at home or outside. If the door/window sensor senses that a window has been opened while the alarm system is active, it immediately triggers an alarm. For increased security, this version also has five vibration sensors with a adjustable sensitivity level. Once the alarm system is activated, you will receive a warning of vulnerabilities such as open doors or windows. Combined with smart radiator termostats, the heating automatically turns off when ventilated.
