Tuya Smart Door Sensor — 2.4GHz App-Controlled Open/Closed Detector (Works with Home Gateway)

This Tuya 2.4GHz door/window sensor uses a one-key connection and requires a home gateway to link with your smart setup. The 2.4GHz protocol delivers a more stable and faster connection for reliable performance. It senses door and window open/closed status and sends instant push notifications to your phone whenever the contact changes. Configure multi-sensor linkage alarms for scenarios like Away mode: if a break-in is detected the sensor will push an alert and trigger a webcam (not included) to record video. You can also set actions such as turning lights on automatically when a door is opened. Remote control and monitoring are available via the APP so you can manage your home anytime, anywhere. Compact and simple to install — the small, adhesive-mounted design lets you place it on doors, windows, drawers and other locations without altering the appearance or structure of your furniture.
