Product Features
-
Smart Ecosystem & Compatibility
It supports the Tuya and Smart Life apps, and seamlessly links with Amazon Alexa and Google Home voice assistants. Users can query the device status via voice commands (e.g., "Alexa, check the status of the bedroom door sensor").
-
Wireless Remote Monitoring
Adopting a WiFi direct-connection design, it requires no additional gateway. Users can remotely check the real-time status of doors/windows anytime and anywhere through the app, without being restricted by location.
-
Low Power Consumption & Battery Life Assurance
Powered by AAA batteries and equipped with low-power technology, it also features a low-battery reminder function. When the battery is about to run out, a notification is pushed via the app to prevent device failure due to power outage.
-
Easy Installation Design
It uses double-sided tape adhesive installation, with no wiring needed. Deployment can be completed quickly by aligning the center line and keeping the installation gap less than 10mm, allowing users to operate it independently.
-
Hardware Structure
The device consists of a main module and a magnetic strip module. The main module is equipped with an LED indicator to intuitively show the working status, while the magnetic strip module achieves accurate detection through magnetic induction.
Functional Advantages
-
Real-time Alarm and Notifications
When the opening gap of a door/window reaches ≥10mm, the device immediately triggers an alarm and sends a real-time notification (e.g., "Door Open Alarm") to the app, enabling timely identification of unauthorized break-ins or abnormal opening/closing behaviors.
-
Convenience of Voice Control
It supports voice interaction with Alexa and Google Home. Users can query the device status via voice commands (e.g., "Google, are all my home doors and windows closed?"), making operation barrier-free.
-
Status Recording and Tracing
The app records the time and duration of each door/window opening and closing, allowing users to trace historical activities (e.g., investigating whether the home door was opened abnormally during unattended periods).
-
Multi-scenario Intelligent Linkage
It can link with devices in the Tuya ecosystem, such as smart cameras, alarms, lights, and air conditioners. For example: it automatically triggers camera recording when a window is opened, and links with a smart air conditioner to turn it off when a door is opened to save energy.
Application Scenarios
-
Home Security Scenarios
Suitable for home doors, bedroom windows, children's room doors/windows, drawers, etc., to prevent security risks such as theft and children accidentally opening windows/drawers.
-
Commercial & Office Scenarios
Can be installed on shop doors/windows, office doors, and warehouse doors to monitor unauthorized break-ins during unattended periods (e.g., nights, weekends).
-
Smart Home Linkage Scenarios
Used with smart air conditioners and fresh air systems, it automatically turns off the equipment when a window is opened to reduce energy waste; or links with smart locks to confirm the status of doors/windows simultaneously when the door is unlocked.
