Enter the WiFi name and password, then change the device name. Right after adding it successfully to your list, you can tap the device to enter its control interface. The real-time temperature will be synchronously displayed on the device interface. Temperature data will be displayed in both ℃ and ℉.
In Auto mode, you can preset a temperature range for your device to turn on or off when the real-time temperature is fall into the range. You can choose to set it turn on when temperature is higher than a specified temperature, and turn off when temperature is lower than another specified temperature. In Auto mode, you can not tap to turn device on/off.
Now I have installed the Sonoff TH with the home temperature sensor in my room. To keep the room comfortable, let me preset it to turn on connected fan when temperature is higher than 36℃, and turn off the fan when temperature is lower than 30℃.
To demonstrate the effect, now I have prepared two cups of water: one is hotter than 36℃, the other is lower than 30℃. While I put the sensor into hot water, the fan is automatically turned on once it cross 36℃. And then I put the sensor to the cold water, the fan is turned off while it is lower than 30℃.
