Large Display, Rich Data, Fast Response
The SONOFF AirGuard TH SNZB-02DR2 is a modern Zigbee temperature and humidity sensor with a large LCD screen, providing an instant overview of your indoor climate while feeding data into your smart home for automation. In practice, this means: fewer “feelings” and more precise decisions for heating, ventilation, humidification, or air conditioning.
AirGuard TH is designed so that you can clearly read the temperature and humidity even from a distance. On the 3.6″ LCD, you can see current values as well as daily highs and lows – perfect for the living room, nursery, office, pantry, or workshop.
- Instant Overview: Temperature, humidity, and 24-hour extremes directly on the display.
- Fine Resolution: Temperature in 0.1 °C increments; humidity on display in 1% RH steps.
- Precision for Automation: Suitable for stricter threshold values in smart scenes.
eWeLink: History, Curves, Dew Point, and VPD
After pairing via a Zigbee gateway, you gain remote monitoring, notifications, and analytics in the eWeLink app – including data curves and calculations such as dew point and VPD (Vapor Pressure Deficit). Practical for healthier ventilation, mold control, and maintaining a stable climate for plants or sensitive storage.
As a central “hub,” the SONOFF Zigbee Bridge Pro or the newer Matter bridge SONOFF ZBBridge-U are ideal. For custom solutions (Home Assistant, Zigbee2MQTT), check out our hubs and adapters.
Remote Temp. & Humi. Display: Room Comparison Without a Phone
Want to know if the nursery is warmer than the living room without getting off the couch? AirGuard TH allows you to display data from another supported SONOFF sensor directly on its screen (in Zigbee mode).
- Supported Sources: SNZB-02, SNZB-02P, SNZB-02D, SNZB-02WD, SNZB-02LD
- Requirement: Both devices must be under the same SONOFF Zigbee gateway.
- Note: Newer device firmware may be required for this function.
Automation Ideas: Comfort, Health, Interior Protection
- Humidifier: Start at low humidity for easier breathing (especially in winter).
- Ventilation: Alerts and scenes for sudden humidity spikes (bathroom, laundry room).
- Heating/AC: Maintain a stable room temperature despite fluctuations.
