There are so many things I love about this thermostat. You can program a set schedule for the heat and air temperature and what time you wish for it to make different changes. The thermostat also can learn from your actions over time and adjust itself. I especially like the away settings so that if we are out of town our air conditioning will not turn down like it would if we were at home. Also, you can use the app to see if you had greater usage one day to the next and why that is such as weather changes or less or more away time. The Nest customer service team is amazing. Our thermostat has moved with us into 3 different houses and they have always been so helpful when we needed it. I absolutely recommend it!
