3. Setup Guide
3.1 Initial Setup
- Download the eWeLink App: Search for 'eWeLink' in your mobile app store (Google Play Store or Apple App Store) and download the application.
- Power On: Connect the SONOFF ZB Bridge-P to a 5V 1A USB power adapter using the provided USB cable. The device will power on.
- Pairing the Bridge: Open the eWeLink app, ensure Bluetooth is enabled on your phone. The app should detect the new device. Tap 'Bluetooth Pairing' to initiate the pairing process for the bridge. Follow the on-screen instructions to complete the setup.

3.2 Adding Zigbee Sub-Devices
Once the ZB Bridge-P is set up, you can add Zigbee sub-devices:
- In the eWeLink app, select your ZB Bridge-P.
- Choose the option to add a new sub-device.
- Put your Zigbee sub-device into pairing mode (refer to the sub-device's manual for specific instructions).
- The bridge will detect and add the sub-device.
The ZB Bridge-P can manage up to 128 sub-devices. Plug-in Zigbee devices can also act as Zigbee routers to extend the network range, improving coverage and signal strength throughout your home.

4. Operating Instructions
4.1 Interoperability between Zigbee and Wi-Fi Devices
The SONOFF ZB Bridge-P operates on the Zigbee 3.0 protocol and is designed to facilitate communication between both Zigbee and Wi-Fi devices. This allows for unified smart control and connection within the eWeLink app, enabling you to create scenes and automations involving devices from both protocols.

4.2 Smart Home Security Modes
The ZB Bridge-P allows you to customize your home security with three distinct modes by setting different arming devices:
- Home Mode: Typically used when you are at home, monitoring specific entry points like doors or windows.
- Away Mode: Activates full security monitoring, including motion sensors and all entry points, when you are away.
- Sleep Mode: A customizable mode for nighttime, perhaps monitoring ground floor windows while allowing movement upstairs.
You can easily arm and disarm your security system through the eWeLink app, a wireless button, NFC trigger, or by scheduling specific times for mode changes.


4.3 Efficient & Reliable Local Smart Scenes
The ZB Bridge-P supports local smart scenes, which function reliably even if your Wi-Fi connection is lost. It features a built-in high-precision local RTC (Real-Time Clock), ensuring that time-based schedules continue to operate correctly even after a short power outage. Once power is restored, the time synchronization will resume without affecting your scheduled scenes. Note that local scenes are exclusively for Zigbee devices.

4.4 Multi-functional Bridge Buzzer
The integrated buzzer in the ZB Bridge-P serves purposes beyond just security alarms. It can be configured for various notifications:
- Doorbell Function: When paired with a wireless button, the bridge can act as a doorbell, alerting you to visitors.
- Reminders: Use it to create custom reminders, such as calling family members for meals.

4.5 Creating a Comfort Home Environment
Integrate temperature and humidity sensors (e.g., SNZB-02) with the ZB Bridge-P to maintain optimal comfort levels in your home. The bridge can automatically trigger other smart devices, such as fans or humidifiers, based on real-time sensor data and your predefined settings.



4.6 Hands-free Control with Smart Assistants
The ZB Bridge-P is compatible with popular smart assistants, including Amazon Alexa, Google Assistant, and SmartThings. This allows you to control your connected devices and inquire about sensor data using voice commands, simplifying your daily routines.
- “Alexa, turn on the light.”
- “Hey Google, what’s the temperature?”

5. Maintenance
To ensure optimal performance and longevity of your SONOFF ZB Bridge-P:
- Keep the device in a dry environment, away from moisture and extreme temperatures.
- Clean the device periodically with a soft, dry cloth. Do not use liquid cleaners or aerosols.
- Ensure proper ventilation around the device to prevent overheating.
- Regularly check for firmware updates through the eWeLink app to benefit from new features and security enhancements.
6. Troubleshooting
If you encounter issues with your ZB Bridge-P, consider the following:
- Device not pairing: Ensure the bridge is powered on and your phone's Bluetooth is enabled. Try restarting the bridge and your phone.
- Zigbee devices not connecting: Make sure the sub-device is within range of the bridge or a Zigbee router. Check if the sub-device is in pairing mode.
- Local scenes not working: Verify that the scene involves only Zigbee devices, as local scenes do not support Wi-Fi devices.
- Voice control issues: Ensure the bridge is correctly linked to your Alexa, Google Assistant, or SmartThings account in the eWeLink app. Check your internet connection.
- Resetting the Bridge: If persistent issues occur, you may need to reset the bridge. Use the provided SIM ejector tool to press and hold the reset button (usually a small pinhole) until the indicator light behaves as described in the quick guide for reset mode.
