Answer

If you encounter an issue where the temperature reading would show incorrect values, or it will show '999' value, please follow these steps to resolve the issue:

• Disconnect from the sensor;
• Close the Sentrius Mobile App;
• Connect again to the sensor using Sentrius App.

Now the app should show correct values.
