Description

This smart contact sensor is designed to alert you instantly when a door or window is opened or closed. Ideal for real-time entry monitoring whether you're home or away, it provides 24/7 coverage through your Wi-Fi connection and the SmartKnight app. The ultra-low power MCU and efficient Wi-Fi module offer extended range up to 40m, depending on the environment.

Installation is straightforward with no gateway device required—just mount it to the door or window and connect via the app. Automate your system by linking it with other devices to trigger actions like turning on lights when an entry point is accessed. It’s compatible with 2.4GHz Wi-Fi networks (not 5GHz).

The built-in low battery alert ensures you’re never caught off guard, and the unit runs on a single DC 3V CR2 battery (included) with an expected lifespan of up to 1 year (based on 20 activations daily). Compact and discrete, it blends into most interiors without drawing attention.

Check your router manual for 2.4GHz setup if needed.
