3. Einrichtung
3.1 Vor der Installation
- Stellen Sie sicher, dass Ihr WLAN-Netzwerk mit 2.4 GHz arbeitet. Das Gerät unterstützt kein 5-GHz-WLAN.
- Laden Sie die eWeLink-App aus dem App Store (iOS) oder dem Google Play Store (Android) herunter.
- Registrieren Sie sich und melden Sie sich in Ihrem eWeLink-Konto an.
- Ensure the sensor has fresh batteries installed (2 x AAA 1.5V batteries).
3.2 Physische Installation
- 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).
- Reinigen Sie die Montagefläche gründlich, um eine ordnungsgemäße Haftung zu gewährleisten.
- 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 Device Pairing with eWeLink App
- Öffnen Sie die eWeLink-App auf Ihrem Smartphone.
- 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').

4. Bedienungsanleitung
4.1 Monitoring Device Status
Einmal gekoppelt, können Sie view the real-time status of your door/window sensor directly from the eWeLink app. The app will display whether the sensor is 'Open' or 'Closed'.
4.2 Empfang von Benachrichtigungen
The sensor is configured to send push notifications to your smartphone whenever the door or window it is attached to changes status (e.g., opens). Ensure notifications are enabled for the eWeLink app in your phone's settings.

6. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Device fails to pair with app | Incorrect Wi-Fi band (5GHz instead of 2.4GHz), incorrect Wi-Fi password, Wi-Fi router settings (e.g., 'b' protocol not enabled), device not in pairing mode. | Ensure your phone is connected to a 2.4GHz Wi-Fi network. Verify Wi-Fi password. Check router settings to ensure 802.11b protocol is supported/enabled. Re-enter pairing mode by holding the button for 5 seconds. Try pairing via Bluetooth option in eWeLink if available. |
| Sensor not reporting status changes | Low battery, incorrect installation gap, Wi-Fi connectivity issues. | Check battery level in the app and replace if low. Ensure the gap between the sensor and magnet is less than 5mm. Verify Wi-Fi signal strength at the sensor's location. |
| Keine Push-Benachrichtigungen | App notifications disabled, phone's power saving mode, network issues. | Check eWeLink app settings and phone's system settings to ensure notifications are enabled. Disable power-saving modes for the app. Ensure stable internet connection. |
| Device disconnects after power/Wi-Fi outage | Temporary network disruption. | Remove and reinsert the batteries to power cycle the sensor. This often helps re-establish the connection after a network interruption. |
| Kurze Akkulaufzeit | Frequent triggers, poor quality batteries, extreme temperatures. | Use high-quality alkaline batteries. Consider the placement to avoid excessive triggering. Ensure the operating temperature is within the specified range. |
