SONOFF SNZB-02UL AirGuard Zigbee Temperature Humidity Sensor – 2.9" E-Ink Display with Time, Date & Weather (Zigbee Hub Required)

Your room's temperature, humidity, time, and weather, all on one clear screen. The SONOFF SNZB-02UL AirGuard is a Zigbee temperature and humidity sensor with a 2.9-inch e-ink display that stays easy to read in bright light with a near-180° viewing angle. Once paired, the screen syncs and shows temperature, humidity, current time, date, weather information, and comfort level icons at a glance. 🌡️🖥️✨

Press the button to view the past 6 hours of readings right on the device, and use the app to view and export up to 6 months of history, including temperature, humidity, dew point, and VPD. With ±0.2°C temperature accuracy, ±2% RH humidity accuracy, and a 5-second refresh, it also triggers smart scenes to switch fans, humidifiers, or other devices automatically.

⚠️ Important Note
A Zigbee gateway is required, and it is sold separately. The time, date, and weather information appear after the device is paired and connected to the network. Please check the package contents for the included power source, as the manufacturer does not list the battery type. ✅📡
