Energizer Connect Smart Door/Window Sensor

Monitor your home's windows, doors, and even cabinets remotely with the DIY friendly Energizer Connect EDW4-1001-WHT Smart Door Window Sensor. With the free Energizer Connect app, you'll be alerted when the contacts separate, indicating something is open. The app also lets you set up some automated sequences based on the sensor. For example, automate compatible connected light bulbs (sold separately) to turn on as soon as you open your front door. This low energy solution gets months of use on battery power. No hardwiring or cables! Just stick on and it's ready to go.
