3.2 Uparivanje sa Zigbee Hub-om
The SONOFF SNZB-02P requires a Zigbee 3.0 compatible hub to function. Follow these general steps to pair the sensor:
- Ensure your Zigbee hub is powered on and in pairing mode. Refer to your hub's specific instructions for entering pairing mode.
- On the SNZB-02P sensor, press and hold the reset/pairing button (usually a small pinhole button) for approximately 5 seconds until the LED indicator flashes rapidly.
- The sensor will attempt to connect to the nearest Zigbee hub. Once successfully paired, the LED indicator will stop flashing or turn solid, depending on the sensor's design.
- Confirm the sensor's connection within your Zigbee hub's application or interface.
The SNZB-02P is compatible with various Zigbee 3.0 gateways, including SONOFF's own hubs, Aeotec Smart Home Hub, Smartthings Hub, Echo Show, Echo 4th Gen, and Echo Plus 2nd Gen.

3.3 Postavljanje
Place the sensor in the desired location for temperature and humidity monitoring. For accurate readings, avoid placing it near heat sources, direct sunlight, or in areas with significant airflow (e.g., directly in front of an air vent). The sensor features a magnetic mount for easy attachment to metal surfaces, or it can be affixed using adhesive or screws (if provided).

4. Uputstvo za upotrebu
4.1 Real-time Data Monitoring
Once paired, the SNZB-02P sensor will transmit temperature and humidity data to your Zigbee hub. You can view this data in real-time through your hub's dedicated mobile application or smart home interface. The data refreshes quickly, typically within 5 seconds, when temperature and humidity fluctuate.

4.2 Pohranjivanje i izvoz podataka
The sensor supports cloud-based historical data recording. Temperature and humidity data for each day, month, or even six months can be stored and accessed through the associated application. This allows for detailed analysis of environmental trends and can help in optimizing your living environment. Data export functionality is also available.

4.3 Smart Scene Creation and Alerts
Leverage the sensor's data to create smart scenes and automation rules within your Zigbee hub's ecosystem. For example, you can set up rules to automatically turn on a fan if the temperature exceeds a certain threshold (e.g., >28°C) or activate a humidifier if humidity drops below a set level (e.g., <45% RH). You can also receive immediate notifications on your phone if the room temperature or humidity exceeds your predefined comfort range.

4.4 Integracija glasovnog upravljanja
The SNZB-02P sensor can be integrated with voice assistants like Amazon Alexa and Google Home through your Zigbee hub. Once integrated, you can simply ask your voice assistant for the current temperature or humidity readings in the room where the sensor is located.

5. Održavanje
5.1 Vijek trajanja baterije i zamjena
The SNZB-02P sensor is designed for extended battery life, typically lasting more than four years under normal usage conditions. When the battery level is low, your Zigbee hub's application may notify you. To replace the battery, open the sensor casing and insert a new CR2450 Lithium Metal battery, ensuring correct polarity. Dispose of old batteries responsibly.
5.2 Čišćenje
To clean the sensor, gently wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as these can damage the device or affect its performance.
6. Otkrivanje problema
- Sensor Not Connecting to Hub:
- Ensure the Zigbee hub is powered on and in pairing mode.
- Verify the sensor's battery is installed correctly and has sufficient charge.
- Press and hold the sensor's reset/pairing button until the LED flashes.
- Približite senzor Zigbee hub-u tokom procesa uparivanja.
- Provjerite ima li smetnji od drugih bežičnih uređaja.
- Netačna očitavanja:
- Ensure the sensor is not placed near direct heat sources (e.g., radiators, direct sunlight), cold drafts, or in areas with significant temperature fluctuations.
- Verify the sensor is clean and free from dust or debris that might obstruct the sensors.
- Compare readings with another calibrated thermometer/hygrometer to confirm discrepancy.
- Data Not Updating:
- Check the Zigbee network connection. A weak signal can cause delayed updates.
- Ensure the sensor's battery is not critically low.
- Restart your Zigbee hub.
- If issues persist, try re-pairing the sensor with your hub.
