Requires a mydlink Smart Home Hub or Amazon Echo Plus
The mydlink DCH-B112 Smart Door/Window Sensor is a discreet contact sensor that detects when a door or window is opened or closed, giving you a trigger for automating your smart home. It works with Amazon Alexa or the Google Assistant for convenient hands-free voice control. Save time, and enjoy a safer, more comfortable home.
Be at Home, Even When You’re Out
No more wondering if you left your door or windows open. The mydlink Smart Door/Window Sensor lets you check on them from anywhere with your phone. It also sends an alert whenever a door or window is opened, or when someone tampers with the sensor by prying it off its surface.
Specially Designed Modules
The DCH-B112 discretely mounts where a door or window meets its frame. When the main sensor unit is separated from the magnetic trigger, mydlink will push out a notification to your mobile device or actions to other connected devices in your mydlink Smart Home network - created by mydlink Smart DIY devices with built-in hub functionality, and it doesn’t rely on Wi-Fi as it uses ZigbeeTM technology to connect to the hub. Alternatively, press the built-in sensor bypass button to open your doors and windows without activating the alert.
Get More Control With mydlink
Set up the DCH-B112 easily via the free mydlink app. Simply download and install the app on your mobile device and follow the step-by-step instructions to quickly configure the sensor.
