Sonoff TH(Temperature Humidity) is a Sonoff version that can monitor and set temperature and humidity through the APP. It supports preset a temperature and humidity range, when the temperature and humidity of the environment has reached the range, it will automatically turn on or turn off connected devices. This module is perfect to connect with electric fan, air conditioner, humidifier. Please note that this version does not have 433 RF function.

Sonoff family is low-cost, affordable device series that help you to step into the amazing smart home. This series of WiFi wireless switch can connect to appliance of different types and brands. Sonoff sends data to cloud platform through the WiFi Router, which enables you to remotely control all connected appliances with the App eWeLink on your smart phone. The server of Sonoff is Amazon AWS global server.
