– Learn to adjust your home’s temperature based on your habits and activity, when you wake and sleep, when you get home from work and when you leave, and so on.

– Anticipate your heating and cooling needs based on local weather —and can even adjust themselves based on humidity.

– Allow you to remotely control your home’s temperature via a smart phone, tablet or desktop. You can see how much you’re spending on heating or cooling costs, tweak the programming to save you money, and see the results immediately.

– See your energy use in real-time.
