The EDW4-1001-WHT Smart Door/Window Sensor from Energizer enables you to receive instant alerts when a door, window, or cabinet is opened or closed. In addition, you’ll be able to automate compatible Energizer Connect devices, such as lights, to power on as you open doors, windows, or cabinets. Remote access to monitor activity from anywhere is possible with the Energizer Connect app for iOS and Android.
This sensor requires two AAA batteries for operation (available separately). The batteries deliver up to four months of battery life.
