SONOFF SNZB-04 ZigBee Wireless Door Window Sensor User Manual

1. Product Overview

The SONOFF SNZB-04 is a ZigBee Wireless Door Window Sensor designed to enhance home security and smart automation. This sensor detects the opening and closing status of doors, windows, drawers, or cabinets, sending real-time notifications to your connected smart home system. It operates on the ZigBee protocol, requiring a compatible ZigBee Bridge or hub for full functionality.

Key features include real-time status synchronization, ultra-low energy consumption for extended battery life, and integration with various smart home ecosystems through a ZigBee bridge. It supports advanced functionalities like scene linkage, allowing the sensor to trigger other smart devices, and provides historical records of open/close events.

2. Setup and Installation

Before installation, ensure you have a compatible ZigBee Bridge or hub (e.g., SONOFF ZigBee Bridge, Amazon Echo with built-in Zigbee hub, SmartThings Hub) and that it is properly set up and connected to your network.

2.1. Pairing the Sensor

1. Ensure your ZigBee Bridge is in pairing mode or ready to add new devices.
2. Locate the pairing button on the SNZB-04 sensor. This is typically a small pinhole button.
3. Using a pin or a thin tool, long press the pairing button for approximately 7 seconds until the indicator light on the sensor flashes quickly.
4. On your ZigBee Bridge's application (e.g., eWeLink app for SONOFF Bridge), enter the gateway settings and select the "Add" or "Add Device" option.
5. The app will begin searching for the device. Keep the sensor close to the hub during this process.
6. Once the device is found and successfully paired, you can modify its name within the application for easy identification (e.g., "Front Door Sensor").

2.2. Physical Installation

The SNZB-04 sensor consists of two parts: a main sensor unit and a smaller magnet unit. For proper operation, these two parts must be installed in close proximity to each other, typically on a door/window frame and the moving part of the door/window.

• Identify the desired location for installation (e.g., door, window, cabinet).
• Clean the surface where the sensor will be mounted to ensure good adhesion.
• Use the included 3M adhesive strips to attach the main sensor unit to the fixed part of the frame and the magnet unit to the moving part (door/window).
• Ensure the two parts are aligned with the small arrow markings facing each other and are within 5mm of each other when the door/window is closed. This ensures accurate detection of open/close states.

3. Operating the Sensor

Once installed and paired, the SNZB-04 sensor operates automatically, detecting changes in the open/close status of the monitored entry point.

3.1. Real-time Status and Notifications

The sensor provides instant updates to your connected ZigBee Bridge and its associated mobile application. When the door or window opens or closes, the status is synchronized in real-time, and you will receive push notifications on your smartphone, keeping you informed of any activity.

3.2. Smart Scene Linkage

Leverage the sensor's capabilities by creating smart scenes within your smart home application. For example:

• Security Alert: If a door opens unexpectedly, trigger an alarm, send a notification, or activate a connected camera.
• Lighting Automation: Turn on lights automatically when a door opens (e.g., entering a dark room) and turn them off when it closes.
• Climate Control: Pause air conditioning or heating when a window is left open.

3.3. Voice Control Integration

The SNZB-04 is compatible with voice assistants like Amazon Alexa and Google Home when connected through a compatible ZigBee Bridge. You can inquire about the status of your doors or windows using voice commands.

Example command: "Hey Alexa, is my door closed?"

3.4. History Records Check

The sensor logs all open and close events, allowing you to review the history of activity for up to 3 months within the mobile application. This feature is useful for monitoring access and reviewing past events.

4. Maintenance

4.1. Battery Replacement

The SONOFF SNZB-04 sensor is powered by a Lithium battery (CR2032, 3V DC). The sensor is designed for ultra-low energy consumption, providing long battery life. However, battery life can vary based on usage frequency and environmental factors.

4.2. Low-Battery Notification

You will receive a notification on your mobile application when the battery level drops to approximately 10% remaining. This prompt allows you to replace the battery in a timely manner to ensure continuous operation of the sensor.

To replace the battery, carefully open the sensor casing, remove the old CR2032 battery, and insert a new one, ensuring correct polarity. Close the casing securely.

5. Troubleshooting

• Sensor Not Responding:
  • Check the battery level. Replace if low.
  • Ensure the sensor is within range of your ZigBee Bridge.
  • Verify the alignment of the main sensor and magnet units. They should be close and aligned when closed.
  • Try re-pairing the sensor with the ZigBee Bridge.
• Pairing Issues:
  • Confirm your ZigBee Bridge is in pairing mode.
  • Ensure the sensor's indicator light flashes quickly after long-pressing the pairing button.
  • Move the sensor closer to the ZigBee Bridge during the pairing process.
  • Check for any interference from other wireless devices.
• Inconsistent Notifications:
  • Check the battery level.
  • Ensure a strong ZigBee signal between the sensor and the bridge. Consider adding ZigBee repeaters if the distance is significant.
  • Verify app notification settings on your smartphone.
