Sonoff SNZB-02D: Smart Zigbee Temperature & Humidity Sensor with LCD Display
The SONOFF SNZB-02D is a Zigbee 3.0 temperature and humidity sensor featuring a large 2.5-inch LCD screen with bold, easy-to-read numbers. It works seamlessly with Zigbee 3.0 gateways such as SONOFF Zigbee Bridge Pro, NSPanel Pro, ZBDongle-P/E, and Alexa with built-in Zigbee Hub. Designed to keep your home comfortable, it visually displays Hot, Cold, Dry, or Wet conditions and includes battery level icons for instant status updates.
Real-Time Monitoring and App Control
The SNZB-02D enables both local and remote monitoring via the LCD screen and supported mobile app. With a range of up to 120 meters (400 feet) in optimal, unobstructed conditions, it updates environmental readings every 5 seconds. If temperature or humidity surpasses your preset thresholds, the app instantly sends alerts, keeping you informed no matter where you are.
High Precision Sensing with Swiss-Made Sensor
Built with a premium Swiss-made sensor, the SNZB-02D delivers high accuracy: ±0.2°C for temperature and ±2% RH for humidity. This ensures dependable monitoring to help you manage indoor comfort and health more effectively.
Smart Automations & Voice Assistant Integration
Set temperature or humidity triggers to automate other smart devices, such as turning on a humidifier when humidity drops below 40%. The SNZB-02D also works with Alexa and Google Home—just ask your assistant for current temperature or humidity updates.
Clear LCD Display & Environmental Icons
The 2.5-inch LCD provides real-time temperature and humidity readings, along with intuitive icons that indicate current air conditions (Hot, Cold, Dry, Wet) and battery level. It's a user-friendly solution for visually tracking your environment at a glance.
Historical Data Logging and Export
Access and analyze temperature and humidity trends via half-year graphs in the app. View historical data by day, month, or year, and export your records in .CSV format for deeper insights or reporting.
Flexible Installation Options
The sensor offers three mounting methods: tabletop stand, magnetic back, or 3M adhesive—allowing placement in any environment such as baby rooms, greenhouses, kitchens, cellars, terrariums, humidors, or guitar rooms.
