Description
The SONOFF AirGuard TH (SNZB-02DR2) is a Zigbee temperature and humidity sensor with a large 3.6-inch LCD screen. At a glance it shows real-time temperature and humidity, the 24-hour highs and lows, and readings from other SONOFF temperature sensors in your home.
Through a Zigbee gateway, the eWeLink app keeps up to 6 months of records with maximum, minimum and average curves, plus dew point and VPD analysis. Reporting intervals are adjustable, and smart scenes can run humidifiers, air conditioners and other devices to keep every room comfortable.
Note: a Zigbee gateway is required for app monitoring, remote readings and automations (see "Works With" below).
