The device detects which door or window is open using a high-end UK reed relay contactor on which the magnetic field acts. It can work in transmitter mode, sending a signal from the wired sensor to the hub. The device even protects windows left open for ventilation. The accelerometer records changes in vertical slope angle, shocks or vibrations and sends an alarm to the hub.
