Sonoff TH10/TH16 WiFi Wireless Switch
Remote Temperature and Humidity Monitoring and Control
Overview
The Sonoff TH16 is a wireless temperature and humidity monitoring switch that allows users to remotely monitor and set temperature and humidity ranges to control connected appliances via the iOS/Android eWeLink app. As its name suggests, the Sonoff TH temperature and humidity monitor device supports a maximum current supply of 16A.
The Sonoff TH16 supports presetting the desired range for temperature or humidity. When the environmental temperature or humidity falls within this range, it will automatically turn connected devices on or off.
Sonoff TH16 is compatible with Si7021 and DS18B20 temperature and humidity sensors.
Using the latest eWeLink app, users can create conditional statements (Smart Scenes) to trigger the on/off status of other smart devices. This enables users to leverage the Sonoff TH16 with a Si7021 or DS18B20 sensor to collect environmental data, which can then be used as a condition to control other devices.
This device is ideal for use with appliances such as electric fans, air conditioners, humidifiers, smart fish tanks, and watering systems.

Remote Control and Timing
Two smartphones side-by-side, both displaying the Sonoff TH app. One shows the ON state with temperature and humidity, the other shows the OFF state with manual/auto modes. This illustrates the remote turn on/off functionality from anywhere, as long as the phone has network connectivity (2G/3G/4G/WiFi).
Timing Schedules
The device supports single/repeat timing tasks and countdown timers. These schedules execute even when the network connection is off.
