Step 3: Download the TUYA Smart App
Download the TUYA Smart APP from your device's app store (e.g., Apple App Store or Google Play Store). Alternatively, you can scan a provided QR code to download the app for iOS/Android.
[Note: QR code for app download is excluded as per instructions.] -
Step 4: Register and Add Device in the App
Register an account using your mobile phone number. On the app's "My Home" interface, tap the "+" icon or "Add Devices" button. Select "Security Sensor" from the categories, then choose "Door Magnetic Sensor".
[App Screenshot Description: Shows the "My Home" screen with an "Add Device" prompt and a subsequent "Add Device" screen listing various device categories including "Security & Sensor" with "Door Sensor" and "sensor (WI-FI)" options.] -
Step 5: Enter Network Connection Mode
Using the pin provided in the accessory package, press and hold the reset key for more than 5 seconds. The indicator light should flash, indicating entry into automatic network connection mode. Follow the on-screen prompts to enter your WiFi password and confirm.

Step 6: Manual Network Connection (if needed)
If the indicator light flashes quickly, press and hold the reset key for 5 seconds with the pin to enter manual network connection mode (indicator flashes slowly). The app may prompt you to choose a compatible mode. Enter your WiFi password and confirm. You may need to switch to your phone's WiFi settings to connect to the device's network (e.g., "Smartlife_XXXX") and then return to the app to continue the adding process.

Step 7: Network Connection Success and Usage
Once the network connection is successful, tap the door magnetic icon in the app. The app will display notifications when the door is opened or closed. For example, it will show "Door Is Open" when the magnetic contact is broken and "Door Is Closed" when it is re-established. You can also view a log of events.
[App Screenshot Description: Shows two screens from the TUYA Smart app. The first indicates "Open Door Alert: Door Is Open" with a visual representation of the separated sensor and magnet. The second indicates "Close Door Alert: Door Is Closed" with a visual of the sensor and magnet together. Both screens include a "Record" section listing past events with timestamps.]
