SONOFF Zigbee Smart Temperature and Humidity Sensor with LCD Display

Sonoff SNZB-02DR2 smart temperature and humidity sensor, Zigbee 3.0, with 3.6" display, powered by 2x AAA batteries
The SONOFF smart home system allows you to control electrical appliances remotely using the "EWeLink" app or by voice with "Amazon Alexa" or "Google Home". It allows you to create various scenarios, group devices by turning on/off multiple devices in your home with one touch, set desired timers and schedules, monitor the status of your home and devices in real time, and share their control. The Sonoff smart home system devices have the built-in ability to operate in a local LAN network without a cloud server.
Features:
The smart device uses a high-precision temperature and humidity sensor SHT40 from the Swiss manufacturer "Sensirion", which measures environmental conditions in real time. The data is displayed on a large LCD screen and transmitted to the eWeLink app.
Connection and configuration are supported directly via the smart app (via Android or iOS smart devices). Temperature parameters can be set in °C / °F.
The device allows you to monitor living conditions in the app, store and export historical data.
The 3.6-inch LCD screen allows you to see real-time temperature and humidity, the highest and lowest 24-hour values, and remote sensor data at a glance.
Through the Zigbee hub, you can monitor temperature and humidity in the eWeLink app, view up to 6 months of historical data with graphs of the highest, lowest, and average values. Dew point and air dryness analysis (VPD) are also provided, helping to better assess the indoor microclimate.
The frequency of temperature and humidity data updates can be flexibly adjusted to your needs: according to set threshold values or selected periodicity.
Suitable for environmental monitoring in residential premises, factories, computer rooms, shopping malls, hotels, offices, educational buildings, banks, libraries, as well as warehouses and many other places.
Supports third-party Zigbee 3.0 hubs, such as Amazon Echo Plus 2nd Gen, Echo 4th Gen, Echo Show 2nd Gen, Aeotec SmartThings Hub (V3).
Works with Amazon Alexa and Samsung SmartThings, so it can be easily included in your smart home ecosystem.
The sensor can be combined with various other products to complement the smart home scenario.
Supports remote temperature comparison using Sonoff SNZB-02, SNZB-02P, SNZB-02WD, SNZB-02D and SNZB-02LD sensors. The screen also shows the temperature of other paired sensors, so you can check the data quickly and conveniently, without having to go to other rooms or check the data on your phone.
The device works together with other smart devices, such as humidifiers, air conditioners, etc., and helps to automatically maintain a comfortable temperature and humidity level in the home.
Note: Amazon Alexa does not support the humidity function.
