Do you want to accurately adjust the temperature in your home per room? In that case, a thermostat with zone control is something for you. This allows you to set the temperature separately in each room where you install a thermostat. That way, you don't have to heat your home office in the weekend. That saves energy. Every thermostat measure the temperature in the room where it's installed. The downside is that not every heating system is suitable for zone control.
