Sonoff Zigbee LCD Smart Temperature Humidity Sensor | SNZB-02WD

Overview:

The SNZB-02WD is a Zigbee-based LCD smart temperature and humidity sensor, engineered with a durable and waterproof IP65-rated design. It uses a breathable membrane to detect external conditions while maintaining internal protection, ensuring reliable performance even in humid or misty environments. This makes it well-suited for outdoor use, such as on windows or in gardens.
Equipped with a 2.2-inch LCD screen, the SNZB-02WD clearly displays real-time temperature and humidity readings. It is resistant to UV radiation, making it ideal for long-term outdoor use under direct sunlight. The sensor can function effectively even in low-temperature environments and provides precise data with an accuracy of ±0.2℃ for temperature and ±2% RH for humidity.
The device supports a wide range of Zigbee 3.0-compatible hubs including Sonoff iHost, NSPanel Pro, ZBBridge series, ZBDongle-E/P, and select Amazon Echo models (excluding humidity support for Amazon Hub). It also integrates with open-source platforms like Home Assistant via the ZBDongle, enabling highly customizable automation and monitoring setups.
Using the eWeLink app, users can view historical temperature and humidity data by day, month, or up to the past six months (180 days). This data can be exported for further analysis. Users can set smart scenes and receive real-time alerts for environmental changes—for example, activating irrigation when humidity drops or sending alerts during unexpected temperature drops in pet enclosures.
