Instant notifications via Wi‑Fi
When a door or window is opened or closed, the sensor immediately sends an alert to the mobile app. Stay informed about activity at home, even remotely.
Easy installation without drilling
The two-part magnetic design mounts in minutes. Its compact, minimalist look blends into your interior.
Smart scenes and automation
Connect the sensor with other devices in the U‑Smart app. For example, automatically turn on lights or activate outlets when the door opens.
The Umax U‑Smart Wi‑Fi door and window sensor detects separation of the magnet from the main unit and logs every opening or closing. It immediately alerts you via your home Wi‑Fi with a phone notification and shows event history and battery status in the clear app. Installation is quick and wireless—simply stick both parts to the frame and sash and pair with the app.
The U‑Smart app brings all your smart devices into one platform. Create smart scenes and automations—for example, turn on a light or a socket when the door opens. With secure, encrypted connectivity and millisecond‑level response, you can rely on stable performance.
