Gosund S2 smart Wi-Fi dörr-/fönstersensor, vit

Unlike ordinary magnetic contact sensors that rely on proprietary hubs, the Gosund S2 connects directly to your 2.4 GHz Wi-Fi network, eliminating extra gateways and simplifying setup. Its slim ABS body mounts discreetly on doors, windows, cabinets, or drawers, while the Tuya/Smart Life app gives you instant open/close alerts and automation triggers from anywhere.

Highlights

• Direct Wi-Fi connection (IEEE 802.11b/g/n, 2.4 GHz) — no hub required
• Magnetic contact sensor with detection gap up to 15 mm
• Real-time push notifications when a door or window opens/closes
• Works with Amazon Alexa and Google Assistant for voice status checks
• Supports smart scenes and routines in Tuya Smart / Smart Life app
• Battery-powered (1x CR2) with 6–12 months typical life
• Easy installation with adhesive tape or screws

In daily use

Mount the sensor on a door frame and the magnet on the door itself. When the door opens, the built-in LED flashes and the app immediately pushes an alert to your phone. You can create automations such as turning on a smart light when the door opens after sunset, or sending a notification if a window is left open for more than five minutes. The sensor remembers its state and reports battery level in the app, so maintenance is hassle-free.
