The NXG-200 is a powerful companion device to existing garage door openers. Powered by the Nexx Home app, it allows one or more users to securely open, close, and monitor their garage door from anywhere in the world. Never worry about whether or not you have left your garage door open again.
Receive instant notifications on who is coming or going from your garage — including alerts in case someone forgets to close the door. Control and share access with multiple people, like your kids, parents, and friends. Or, securely open the door for a guest who arrives while you’re away. The Nexx NXG-200 works with iOS, Android, Amazon Alexa, Google Home, Siri and SmartThings … no subscriptions required.
