5. Installationsanleitung
5.1 Initial Setup of RF Bridge R2
- eWeLink-App herunterladen: Suchen nach "eWeLink" in your mobile app store (iOS or Android) and download the application.
- Einschalten: Connect the RF Bridge R2 to a 5V USB power source using the provided micro USB cable.
- Schnellkopplungsmodus aktivieren: After powering on, use a needle or a small pin to poke the reset hole on the device for 5 seconds. The Wi-Fi LED indicator will change, cycling through two short flashes and one long flash, indicating it's in quick pairing mode.
- Gerät in der App hinzufügen: Open the eWeLink app, tap the "+" icon, and select "Quick Pairing". Follow the on-screen prompts to connect the RF Bridge R2 to your 2.4GHz Wi-Fi network. Ensure your smartphone is close to the Wi-Fi router during this process.

5.2 Pairing 433MHz RF Devices (Sensors/Remotes)
Sobald die RF Bridge R2 mit der eWeLink-App verbunden ist, können Sie 433-MHz-RF-Geräte hinzufügen:
- In the eWeLink app, tap on your RF Bridge R2 device.
- Select the type of RF device you want to add (e.g., 1-button, 2-button, Alarm for sensors).
- Follow the app's instructions to put your RF device into learning mode (e.g., long-press a button on the remote or trigger the sensor). The RF Bridge R2 will emit a peak beep when it successfully learns the code.
- Repeat for all desired buttons/sensors.
Notiz:
- The RF Bridge R2 supports fixed code 433.92MHz frequency devices (e.g., PT2260, PT2262, PT2264, EV1527). It does NOT support rolling code or dynamic code devices.
- You can add up to 16 RF devices or alarms.

6. Bedienungsanleitung
6.1 Alarmfunktionen
When a 433MHz sensor (like DW2-RF or PIR3-RF) is added as an alarm device to the RF Bridge R2, it can trigger notifications in the eWeLink app.
- Ensure your DW2-RF or PIR3-RF sensor is successfully paired to the RF Bridge R2 as an "Alarm" type.
- When the sensor is triggered (e.g., door opens, motion detected), the RF Bridge R2 will receive the signal.
- An alarm notification will be displayed on your eWeLink app, and recorded in the device history.

6.2 Intelligente Szenen erstellen
Smart scenes allow you to automate actions based on sensor triggers or remote control presses.
- Navigieren Sie in der eWeLink-App zum Abschnitt „Szene“.
- Tap the "+" icon to create a new scene.
- Auslöser festlegen: Choose a smart device (e.g., your DW2-RF sensor) as the trigger. For example, "when the door opens".
- Aktion hinzufügen: Select the action to perform, such as turning on/off a light bulb or another Wi-Fi/ZigBee device connected to eWeLink.
- Name and save your scene.
