SONOFF Zigbee Indoor Temperature Humidity Sensor, 2-Pack

The SNZB-02D is a Zigbee-enabled LCD indoor temperature and humidity sensor that supports voice control. By simply asking "Alexa", you can instantly know the temperature of any room where the SNZB-02D is placed.

The sensor offers three convenient installation methods - it can stand on a table, magnetically attach to a metal surface, or adhere to any smooth surface using the included 3M adhesive. This versatility makes it suitable for a variety of locations, such as baby rooms, bedrooms, greenhouses, reptile terrariums, humidifiers, cellars, incubators, and more.

To maintain a comfortable living environment, users can set desired temperature and humidity ranges within the accompanying app. Once the readings exceed the pre-set thresholds, the app will instantly send alerts, allowing you to take appropriate action.

Specification-wise, the SNZB-02D connects wirelessly via the Zigbee 3.0 protocol and is powered by a CR2450 (3V) battery with an expected lifespan of 2 years. It can operate within a temperature range of -9.9°C to 60°C and a humidity range of 5% to 95% RH (non-condensing).

The sensor's remote monitoring capabilities allow users to check the ambient temperature and humidity anytime, anywhere, via the app. It also provides push notifications when the conditions fall outside the defined comfort range.

Compatible with a variety of Zigbee 3.0 gateways, including the SmartThings hub V3, AeoTec Smart Home Hub V3, Echo Plus 2nd, Echo 4th Gen, Echo Show 2nd, SONOFF ZBBridge-P, ZBBridge, ZBDongle-P, ZBDongle-E, iHost, and NSPanelPro, the SNZB-02D can be easily integrated into existing smart home ecosystems.

Pairing the sensor with a Zigbee hub is a straightforward process - simply press the button on the back for about 5 seconds until the broadcast icon starts flashing, then search and pair the device through your hub.

The SNZB-02D offers remote real-time monitoring, with a coverage of up to 120m/400ft (in unobstructed, ideal conditions), allowing you to check the latest data anytime. It features a built-in Swiss-made smart hygrometer sensor that delivers accurate readings, maintaining ±0.2°C/±0.4°F in temperature and ±2%RH in humidity, with a fast 5-second refresh rate.

The large LCD display makes it easy to view the real-time temperature and humidity values clearly and dynamically, while the intuitive display icons provide at-a-glance information about the room conditions and battery status.

The sensor also offers app-based notifications, alerting you when the temperature or humidity exceeds your set comfort level. Furthermore, it provides up to half-year of free cloud storage for your data, allowing you to view hourly readings, as well as the highest and lowest values at any given hour or day. The data can also be exported as files for further analysis.

In summary, the SNZB-02D Zigbee LCD Intelligent Temperature Humidity Sensor is a versatile and feature-rich device that can help you maintain a comfortable living environment, with remote monitoring, smart notifications, and comprehensive data management capabilities.
