2. Setup and Installation

2.1 Package Contents

• SONOFF SNZB-04P Door and Window Sensor (Main Unit)
• Magnet Component
• 1 x C Battery (pre-installed or included)
• Adhesive Tape (for mounting)
• User Manual (this document)

2.2 Battery Installation

The SNZB-04P sensor requires one C battery, which is typically included. If not pre-installed or if replacement is needed:

1. Gently open the battery compartment cover on the main sensor unit.
2. Insert the C battery, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

2.3 Pairing with a Zigbee Hub

To use the sensor, it must be paired with a compatible Zigbee hub (e.g., SONOFF Zigbee Bridge Pro, NSPanel Pro, iHost, ZBDongle-E, or Echo Plus 2nd Gen). Follow these general steps:

1. Ensure your Zigbee hub is powered on and in pairing mode. Refer to your hub's specific instructions for entering pairing mode.
2. On the SNZB-04P sensor, press and hold the pairing button (usually a small button or pinhole) for approximately 5 seconds until the LED indicator flashes, indicating it's in pairing mode.
3. Once successfully paired, the LED indicator will stop flashing, and the sensor will appear in your Zigbee hub's connected device list or associated mobile application.
4. Rename the sensor in your app for easy identification (e.g., "Front Door Sensor", "Bedroom Window").

2.4 Mounting the Sensor

The sensor consists of two parts: a main unit and a smaller magnet. They should be mounted on the door/window frame and the door/window itself, respectively, with a gap of no more than 10mm when closed.

1. Clean the desired mounting surfaces thoroughly to ensure good adhesion.
2. Peel off the protective film from the adhesive tape on both sensor components.
3. Attach the main unit to the fixed part of the door/window frame.
4. Attach the magnet component to the moving part of the door/window, aligning it with the main unit. Ensure the alignment marks on both parts are facing each other.
5. Verify that the sensor registers "closed" when the door/window is shut and "open" when it is opened. Adjust position if necessary.

3. Operating the Sensor

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

3.1 Status Detection

• When the door or window is closed, the main unit and magnet are in close proximity, indicating a "closed" status.
• When the door or window is opened, the main unit and magnet separate, indicating an "open" status.
• This status change is immediately communicated to your Zigbee hub.

3.2 App Notifications

Configure your Zigbee hub's mobile application to receive real-time notifications on your smartphone whenever the sensor detects an open or close event. This is crucial for security monitoring.

3.3 Smart Scene Automation

Leverage the sensor's capabilities by creating smart scenes or automations within your Zigbee ecosystem. Examples include:

• Security Alert: If a door opens when the security system is armed, trigger an audible alarm and send a notification.
• Lighting Control: Turn on hallway lights automatically when the front door opens after sunset.
• Climate Control: Pause air conditioning if a window is left open for more than 5 minutes.
• Camera Activation: Start recording on a security camera when a specific door opens.

4. Maintenance

4.1 Battery Replacement

The sensor is powered by a C battery. When the battery level is low, your Zigbee hub's application may send a notification. Replace the battery as follows:

1. Gently open the battery compartment cover.
2. Remove the old C battery.
3. Insert a new C battery, observing correct polarity.
4. Close the battery compartment cover securely.
5. Dispose of the old battery responsibly according to local regulations.

4.2 Cleaning

To maintain optimal performance, occasionally clean the sensor units:

• Wipe the exterior of the sensor with a soft, dry cloth.
• Do not use liquid cleaners, aerosols, or abrasive solvents, as these can damage the device.

5. Troubleshooting

5.1 Sensor Not Connecting to Hub

• Check Battery: Ensure the battery is correctly installed and has sufficient charge.
• Proximity: Make sure the sensor is within range of your Zigbee hub. Walls and obstacles can reduce signal strength.
• Pairing Mode: Confirm both the sensor and hub are in pairing mode during the pairing process.
• Reset Sensor: If issues persist, try resetting the sensor (refer to specific reset instructions if available, usually by holding the pairing button for an extended period or removing/reinserting battery). Then attempt pairing again.
• Hub Compatibility: Verify your Zigbee hub is compatible with Zigbee 3.0 protocol.

5.2 Inaccurate Open/Close Detection

• Alignment: Ensure the main unit and magnet are properly aligned and within the recommended 10mm gap when the door/window is closed.
• Mounting Surface: Check if the sensor is securely mounted and not shifting.

5.3 No App Notifications

• App Settings: Verify that notifications are enabled for the sensor in your Zigbee hub's mobile application settings.
• Phone Settings: Check your smartphone's notification settings to ensure the app is allowed to send notifications.
• Internet Connection: Ensure your Zigbee hub has an active internet connection if notifications rely on cloud services.
