6. Operating Instructions
6.1 Dual Load Control
The MINI-ZB2GS-E allows independent control of two connected loads (e.g., two separate lights or appliances) through its dual-gang design.
6.2 Detach Relay Mode
In detach relay mode, the physical switch button and the smart control are decoupled. This means that even if the physical wall switch is turned off, the smart lights connected to it will not lose power and can still be controlled via the app or voice commands. This ensures your smart lights remain 'smart' at all times.
6.3 Zigbee Mesh Network Functionality
The Orb-ZBW2 can act as a Zigbee signal repeater (router) within your Zigbee mesh network. This extends the range and strengthens the reliability of your Zigbee signals, ensuring better communication between your Zigbee devices.
6.4 Smart Home Integration
The device supports integration with various smart home platforms:
- Apple Home via Matter Bridge: Integrate SONOFF Zigbee devices into your Apple ecosystem using a Matter Bridge (e.g., ZBBridge-U, iHost, NSPanel Pro, or self-hosted software on Raspberry Pi/Virtual machines/NAS with a ZB Dongle).
- Home Assistant: Seamlessly integrates with Home Assistant via ZHA or Z2M. The Zigbee Binding function allows direct control between compatible devices (e.g., SNZB-01M button to Orb-ZBW2) without requiring a gateway after initial setup.
- Voice Control: Compatible with Amazon Alexa, Google Assistant, and Siri for hands-free control.
- eWeLink App: Full control and management through the eWeLink app, including setting timers, creating smart scenes, and managing power-on states.
6.5 Advanced Features
- Timers & Schedules: Set precise on/off times for connected devices.
- Smart Scenes: Create automated routines based on triggers from other smart devices (e.g., motion sensor detects movement, turns on light via Orb-ZBW2).
- Power-On State: Configure the device's state (on/off/restore last state) after a power outage.
7. Maintenance
- Keep the device clean and dry.
- Avoid exposing the device to extreme temperatures or humidity outside its specified operating range.
- Do not attempt to disassemble or repair the device yourself. Contact support if issues arise.
- Regularly check for firmware updates through the eWeLink app or your chosen smart home platform to ensure optimal performance and security.
8. Troubleshooting
- Device not responding: Check if the device is powered correctly and if your Zigbee hub is online and within range. Try restarting the Zigbee hub.
- Pairing issues: Ensure you are using a compatible Zigbee hub. Make sure the device is in pairing mode (refer to the eWeLink app instructions for specific steps). Ensure the device is close enough to the hub during pairing.
- Intermittent connection: This could be due to a weak Zigbee signal. The Orb-ZBW2 acts as a router, so ensure it's strategically placed to strengthen your mesh network. Avoid placing it near large metal objects or other sources of interference.
- Voice control not working: Verify that the device is correctly linked to your Alexa, Google Home, or Siri account and that the voice commands are correctly phrased.
9. User Tips
- For optimal Zigbee network performance, ensure you have a robust mesh network with enough router devices. The Orb-ZBW2 can contribute to this by acting as a repeater.
- When integrating with Home Assistant, explore the 'Device Binding' feature for direct control between compatible Zigbee devices, reducing reliance on the central hub for certain actions.
- Utilize the detach relay mode for smart bulbs to maintain their smart functionality even when the physical switch is toggled off.
