SONOFF Zigbee Temperature and Humidity Sensor – SNZB-02P

The SONOFF SNZB-02P Zigbee Temperature and Humidity Sensor is designed to provide precise and reliable environmental monitoring for smart homes and professional automation systems. Using Zigbee 3.0 technology, it ensures fast response times, low power consumption, and stable connectivity with a wide range of Zigbee hubs including SONOFF iHost, NSPanel Pro, ZB Bridge Pro, ZBDongle-E, and compatible third-party gateways. The sensor delivers high-accuracy temperature measurements with ±0.2°C precision and humidity readings with ±2% RH accuracy, refreshing data every 5 seconds for near real-time monitoring. Users can receive instant push notifications via the eWeLink app when preset thresholds are exceeded, helping protect sensitive environments such as nurseries, storage rooms, or offices. SNZB-02P supports up to six months of cloud-based historical data storage, allowing users to review daily, monthly, or long-term trends and export data for analysis. When paired with a Zigbee hub, it enables smart automation by triggering connected devices such as fans, heaters, air conditioners, or humidifiers based on temperature or humidity changes. Powered by a CR2477 coin cell battery, the sensor provides up to four years of typical use without wiring. Its compact design supports wall mounting or tabletop placement, making it suitable for flexible installation in various indoor environments.
