Installationshandbuch

1. Einlegen der Batterie

The SNZB-02D sensor typically comes with a CR2450 battery pre-installed. If not, or if you need to replace it:

1. Öffnen Sie vorsichtig die Rückseite des Geräts.
2. Insert the CR2450 battery, ensuring the positive (+) side faces upwards.
3. Schließen Sie die hintere Abdeckung sicher.

2. Pairing with a Zigbee Hub

The SNZB-02D requires a Zigbee hub (e.g., SONOFF Zigbee Bridge, Alexa with built-in Zigbee Hub, Home Assistant with Zigbee dongle) to function with the eWeLink app and other smart home platforms.

1. Stellen Sie sicher, dass Ihr ZigBee-Hub eingeschaltet und im Kopplungsmodus ist. Informationen zum Aktivieren des Kopplungsmodus finden Sie in der spezifischen Anleitung Ihres Hubs.
2. On the SNZB-02D sensor, locate the pairing button (usually a small pinhole button on the back).
3. Press and hold the pairing button for approximately 5-7 seconds until the network indicator on the LCD screen starts blinking, indicating it's in pairing mode.
4. Once successfully paired, the network indicator will stop blinking and remain steady. The sensor will appear in your eWeLink app or connected smart home platform.

Note: If pairing difficulties occur, especially with Hubitat, some users report success by removing the battery for 10 seconds, starting pairing on the hub, then re-inserting the battery and holding the pairing button for 7-10 seconds until the icon blinks. If still unsuccessful, try pressing and releasing the reset button quickly every 2-3 seconds until the hub detects the device.

3. eWeLink App Integration

After pairing with your Zigbee hub, the sensor should automatically appear in your eWeLink app (if using a compatible SONOFF hub) or the app associated with your Zigbee gateway.

1. Download the eWeLink app from the App Store or Google Play Store.
2. Registrieren Sie sich oder melden Sie sich in Ihrem eWeLink-Konto an.
3. Ensure your Zigbee hub is added and online in the app.
4. The SNZB-02D sensor should appear under your devices. You can rename it for easier identification.

4. Integration von Sprachassistenten (Alexa & Google Home)

To control or query the sensor using voice commands, ensure your Zigbee hub is linked to your Alexa or Google Home account.

1. Öffne die Alexa- oder Google Home-App.
2. Enable the "eWeLink Smart Home" skill (or the skill corresponding to your Zigbee hub).
3. Link your eWeLink account (or hub account) with the voice assistant.
4. Discover new devices. Your SNZB-02D sensor should now be controllable via voice commands (e.g., "Alexa, what's the temperature in the living room?").

5. Integration von Home Assistant

The SNZB-02D can be integrated with Home Assistant via a Zigbee dongle and the eWeLink add-on or other Zigbee integrations.

1. Ensure your Home Assistant instance has a compatible Zigbee integration (e.g., ZHA, Zigbee2MQTT) set up with a Zigbee USB dongle.
2. Follow the pairing steps for your specific Zigbee integration to add the SNZB-02D as a new device.
3. Once added, the temperature and humidity entities from the sensor will appear in Home Assistant, allowing for automation and monitoring.

Bedienungsanleitung

1. Ablesen des LCD-Displays

The large LCD screen dynamically displays the current temperature and humidity. The top number indicates temperature, and the bottom number indicates humidity. Icons for network status, battery level, and comfort level are also visible.

2. Umschalten der Temperatureinheiten (°C/°F)

To toggle between Celsius and Fahrenheit, double-tap the pairing button on the back of the device. The display will instantly switch units.

3. App Monitoring and Alerts

Through the eWeLink app (or your smart home app), you can view real-time temperature and humidity data remotely. You can also set custom thresholds for temperature and humidity. If the readings go above or below your set comfort levels, you will receive instant notifications on your smartphone.

4. Datenspeicherung und -export

The sensor stores up to half a year of historical temperature and humidity data in the cloud. You can access this data via the eWeLink app to view hourly, daily, or monthly trends. The app also allows you to export this data for further analysis.

5. Intelligente Szenenautomatisierung

Leverage the sensor's data to create intelligent automation routines within your smart home system. For example, you can set a smart scene to automatically turn on a humidifier if the humidity drops below a certain percentage, or activate an air conditioner if the temperature rises too high.

Installation und Platzierung

The SONOFF SNZB-02D offers versatile installation options to suit various environments:

• Tischständer: Utilize the built-in kickstand to place the sensor on any flat surface, such as a desk, shelf, or nightstand.
• Magnetische Befestigung: The sensor features a magnetic back, allowing it to be easily attached to metallic surfaces like refrigerators or magnetic boards.
• 3M Klebstoff: For non-metallic surfaces, use the provided 3M adhesive to securely mount the sensor to walls, cabinets, or other desired locations.

Choose a location that provides accurate readings for the area you wish to monitor. Avoid placing the sensor near heat sources (e.g., direct sunlight, vents, appliances) or in areas with extreme drafts, as this can affect accuracy.

Wartung

1. Batteriewechsel

The sensor is powered by a CR2450 button cell battery. When the battery level is low, a low battery indicator will appear on the LCD screen and you may receive an alert in the eWeLink app. To replace the battery:

1. Öffnen Sie vorsichtig die Rückseite des Geräts.
2. Entfernen Sie die alte CR2450-Batterie.
3. Setzen Sie eine neue CR2450-Batterie ein und achten Sie darauf, dass die positive Seite (+) nach oben zeigt.
4. Schließen Sie die hintere Abdeckung sicher.

Typical battery life is approximately 16 months, but this can vary based on usage and environmental conditions.

2. Reinigung

To maintain optimal performance and display clarity, clean the sensor periodically:

• Wischen Sie die Außenseite des Geräts mit einem weichen, trockenen Tuch ab.
• Do not use liquid cleaners, aerosols, or abrasive solvents, as these can damage the device.
• Ensure no moisture enters the device, especially around the sensor openings.
