3. Configuració
3.1 Abans de la instal·lació
- Assegureu-vos que la vostra xarxa Wi-Fi sigui de 2.4 GHz. El dispositiu no admet Wi-Fi de 5 GHz.
- Baixeu l'aplicació eWeLink des de l'App Store (iOS) o Google Play Store (Android).
- Registra't i inicia la sessió al teu compte d'eWeLink.
- Ensure the sensor has fresh batteries installed (2 x AAA 1.5V batteries).
3.2 Instal·lació física
- Identify a suitable location on your door or window frame. The main sensor unit and the magnetic strip must be mounted on adjacent surfaces (e.g., one on the door and one on the frame).
- Clean the installation surface thoroughly to ensure proper adhesion.
- Peel off the protective film from the 3M adhesive on the back of both the main sensor unit and the magnetic strip.
- Attach the main sensor unit to the fixed part of the door/window frame.
- Attach the magnetic strip to the moving part of the door/window, aligning it with the main sensor unit. Ensure the alignment marks on both parts face each other.
- The gap between the main sensor unit and the magnetic strip must be less than 5mm when the door/window is closed for proper operation. This is recommended for non-metallic surfaces.

3.3 Emparellament de dispositius amb l'aplicació eWeLink
- Obriu l'aplicació eWeLink al vostre telèfon intel·ligent.
- Ensure your phone is connected to the 2.4GHz Wi-Fi network you intend to use for the sensor.
- Press and hold the pairing button on the main sensor unit for 5 seconds until the LED indicator flashes rapidly. This indicates the device is in pairing mode.
- In the eWeLink app, tap the '+' icon at the bottom center or top right to add a device.
- Select 'Add Device' and follow the on-screen instructions. The app should detect the DW2 sensor.
- Confirm your Wi-Fi network and enter the password when prompted.
- Wait for the app to connect to the device. Once successfully paired, the LED indicator on the sensor will stop flashing and remain solid for a few seconds before turning off.
- You can rename the device in the app for easier identification (e.g., 'Front Door Sensor', 'Bedroom Window').
