tado° is a Smart Thermostat that revolutionises your heating and saves up to 31% in heating costs. If you leave your heating system turned on during the day while you are not at home, a huge amount of energy will be wasted. If you turn it off during the daytime you will return to a cold home in the evening. To solve this, tado° has developed an intelligent solution which goes far beyond programmable thermostats: It acts automatically and does not require any annoying programming of presence times. tado° controls your heating automatically via smartphone by detecting with the help of location services whether someone is at home right now or not. As soon as the last person has left home the heating will automatically be turned down in order to save energy. As soon as you are starting your return home the system will raise the heating temperature again so that your home will be warmed up for you.
