I love having a smart thermostat in my house.
My mother got me a smart thermostat for my birthday and it was such a thoughtful gift. A smart thermostat is the best type of temperature control on the market. How it works is through wifi. You download the app on your phone, tablet and computer and then can control the thermostat through that. There is more than just heating or cooling and off and on. The thermostat can be set on timed programs. Wake up at 9 am heating and have it turn off for when you leave. You can set times and days of the week with different HVAC. Even if you happen to forget or break routine, it is no big deal. The thermostat scans the home for people. If you come home unexpectedly, the thermostat will find you and turn on. If you leave earlier than usual, the HVAC is powered off by the thermostat. The smart thermostat even alerts on inefficient temperature settings, poor air quality and when an air filter change is needed. This thermostat can literally do no wrong. If you want to save energy, the thermostat is more than willing to help. It will help assist you with setting the home right to save energy. I love having a smart thermostat in my house. I really want to go one step further though. I would like to have HVAC zone control. I would need to install a ductless HVAC unit and set up indoor air handlers in each room. Then I can have many thermostats with different programs going at the same time.
