After the first year this app has done whatever the hell it wants to! It's so frustrating to be at work and check the temperature to turn it up so when I get home it's warm to find out that it's been heating the house to 68 degrees all day! Another one of its tricks is to turn the heat down to 60 degrees during the night! When it's 5 degrees outside, I keep the temperature at 64 at night. When I get cold during the night, I find out the stupid app turned the temperature down to 60° again!.
