Smart Door and Window Sensor: Local Alert and Smartphone Notification
Protect your doors, windows, drawers, cabinets, and sensitive access points with the Tuya WiFi door/window sensor with 90dB siren , a smart solution that's simple to install and easy to manage via the Tuya Smart / Smart Life app. When the magnetic contact detects an opening, the device can immediately activate the integrated audible alarm, flash the red LED, and send a push notification to your smartphone , so you know what's happening even when you're away. Compact, discreet, and wireless, this WiFi magnetic sensor for doors and windows connects directly to your 2.4GHz WiFi network without the need for additional hubs. You can check the open/closed status from the app, arm or disarm the sensor, program automatic activation times, and customize the functions to suit your needs. Ideal for your home, office, shop, garage, warehouse, or second home, it offers a practical way to increase access security and receive immediate alerts in the event of suspicious openings. Compatible with Alexa and Google Assistant , it also allows you to check the status of doors and windows via voice control, making security management even more convenient and intelligent.
Double alarm with 90dB siren and immediate notification on app
When the sensor detects the opening of a door or window, it immediately activates a dual alert system : the built-in siren sounds directly in the room and the red LED flashes to visually signal the alarm. At the same time, the Tuya Smart / Smart Life app sends a push notification to your smartphone, so you can immediately know what's happening even when you're away. The 90dB siren helps draw attention to the situation, while the app alert allows you to monitor the event in real time. This is a very useful feature for entrances, windows, balconies, secondary doors, garages, offices, shops, drawers, or sensitive cabinets. This way, the sensor not only detects the opening, but also immediately alerts both locally and remotely, offering a more comprehensive level of smart protection for homes and professional environments.
It installs in minutes and is almost unnoticeable.
Thanks to its small and lightweight design, the sensor can be easily installed on doors, windows, cabinets, drawers, or cabinets without being invasive. The 3M double-sided adhesive allows for quick, clean, and drilling-free installation, ideal for those who want to add smart protection without modifying doors or windows. For proper operation, the main body and the magnet must be aligned and maintain a distance of less than 15 mm when the door or window is closed. It is recommended to install it away from strong magnetic fields to ensure more stable detection of opening and closing.
Ask Alexa or Google if the door is open
Smart Life app control with notifications and history
Control via the Tuya Smart / Smart Life app makes the door/window sensor even more convenient for everyday use. After connecting it to the 2.4GHz WiFi network, you can monitor the device's status directly from your smartphone, check whether the contact is open or closed, and receive instant notifications when an opening is detected. The app also records events, allowing you to view the history of activations, armings, and disarmings. This is useful for knowing when a door, window, drawer, or cabinet has been opened, even if you weren't there at the time. Setup is simple: connect the sensor to WiFi, download the Tuya Smart or Smart Life app, add the device, and you can start monitoring access right away.
It activates when you leave and deactivates when you return
You don't have to remember to turn the alarm on or off every time. With the scheduler, you can set the Tuya door/window sensor to automatically activate when you leave the house and deactivate when you return. This is a very convenient feature for everyday life: you can protect your front door, windows, garage, office, or shop only at the times you really need it. For example, you can activate it in the morning when you leave for work, at night while you sleep, or during business closing hours. This way, the sensor works more intelligently: it alerts you when it detects a suspicious opening, but avoids unnecessary alarms when you're at home and using doors or windows normally.
Customizable functions from the app: alarm delay, siren duration and volume
From the Tuya Smart / Smart Life app, you can customize the sensor's behavior to suit your needs. You can adjust various settings, such as the alarm delay , siren duration , alert volume , and closing reminder, so the device better adapts to the environment in which it is installed. This feature is useful when you want to avoid false alarms or make the sensor more convenient for everyday use. For example, you can set a short delay before the alarm is activated, choose how long the siren should sound, or adjust the volume based on the type of environment: home, office, shop, garage, or warehouse.
Protect not just the door, but everything that matters
This sensor isn't just for your home entrance. You can also use it on windows, drawers, cabinets, display cases, garages, or safety deposit boxes , giving you more complete control over important spaces. It's perfect for knowing immediately if someone opens a door, window, or container that should be left closed.
