Ledgebit Smart Wi-Fi Door & Window Sensor – Security Alarm

The Ledgebit Door & Window Sensor helps secure your home by alerting you when a door or window is opened. This small magnetic sensor installs quickly on any entrance and sends instant notifications to your phone via the Smart Life or Tuya App—no hub needed, thanks to direct Wi‑Fi connection.

As soon as the magnetic contact between the sensor and its magnet breaks, the system immediately sends an alert. This action helps protect your home from unauthorized entry. You can also set up smart routines. For example, have your lights flash when the front door opens after dark, or receive an alert if a window opens during your sleep hours.

Installation takes only minutes: stick the sensor and magnet in place using included adhesive or screws. Both parts are compact and fit neatly into your home’s décor without being noticed. They align precisely—just follow the simple guide, and you’re ready.

The sensor uses a long-lasting battery that can run for more than a year. You’ll receive a low-battery notification in the app, so you won’t worry about unexpected power loss. Its energy-efficient design stays connected without draining battery life.

You can also integrate this sensor with other products in the Smart Devices Collection or create automation with devices from our Smart Sensors Collection.

It works with Amazon Alexa and Google Home, allowing you to check whether doors are open or armed using voice commands.

In short, the Ledgebit Door & Window Sensor combines simplicity and smart control in a compact unit. It offers real-time alerts, easy installation, and flexible smart-home integration. Whether you’re home or away, this sensor quietly keeps your space safe.
