EVE 20EBN9901 Door & Window Contact Sensor: Matter-enabled for cross-platform compatibility
This smart contact sensor is for homeowners who want to know when a door or window opens, like checking if the kids got home safely or if a pet slipped outside. While many focus on security, this device offers peace of mind through simple, reliable automation that works without fuss.
You can set it to turn on lights when the back door opens at night, so you never walk into a dark house. The Matter compatibility means it connects easily with Apple Home, Alexa, or Google Home, letting you check status from any device. With Thread technology, it responds quickly—you get a notification before you even hear the door close.
It operates locally without a cloud, keeping your data private. Just install it and forget it, knowing your home is smarter and more secure.
