The Sonoff SNZB-02P is a Zigbee 3.0 temperature and humidity sensor designed to keep you informed about your indoor climate. It utilizes a Swiss-made hygrometer to provide precise readings, with temperature accuracy within ±0.2°C and humidity within ±2% RH across a range from -10°C to 60°C. Because it refreshes data every 5 seconds, you can monitor environmental changes in real time through the eWeLink app, which also stores six months of cloud history and allows you to export data logs. This compact device is housed in a white polycarbonate shell measuring 45 x 45 x 17.7 mm, making it discreet enough to place anywhere in your home. You can easily install it by sticking it to a surface or mounting it on a wall without needing any tools. It runs on a single CR2477 coin cell battery that typically lasts up to 4 years, reducing the need for frequent maintenance. Designed for versatility, the sensor integrates with various hubs including the Sonoff Zigbee Bridge, iHost, and NSPanel Pro, as well as Echo 4th Gen and SmartThings Hub V3. This connectivity allows you to set comfort threshold alerts and coordinate with Google Assistant or Alexa to automate your home environment based on the current weather conditions.
