How does the Smart Thermostat connect?

The tado° Smart Thermostat connects to the internet via your internet access at home. The Smart Thermostat and your mobile devices are connected via tado° secure cloud server. Of course you can still control your heating via the Smart Thermostat if your internet connection goes down - this just temporarily prevents control via your phone or the web app.

tado° makes sure that no energy is wasted. With the help of the Smartphone App tado° automatically knows how far you are away from your home. tado° carefully reduces the temperature to an optimal level as soon as the last person has left home. It keeps in mind how to pre-warm the home most efficiently for your return. This cuts overall heating costs by up to 31%.

tado° checks the weather forecast

tado° constantly monitors the weather forecast so it knows when it's best to let the sun warm your home. This saves more energy and keeps your room temperature at a comfortable level. Do you have underfloor heating? Then this is definitely a feature for you!

With tado° you can easily control your underfloor heating, even if you don't have your own boiler (e.g. district heating). In this setup every room acts as its own "zone".tado° quickly learns about the special characteristics of your underfloor heating and uses the weather forecast for forward-looking regulation.

See how you save with the mobile app.

Keep an eye on how tado° is heating your home with the tado° mobile app - wherever you are. Take control if you like. Change the settings on the go or switch to manual mode - everything's just a few clicks away with tado°mobile app for Android, iOS and Windows phones and tablets. The report shows you when your heating was on and what triggered it. Want to know how much you spent on heating today? tado°mobile app will tell you with just a swipe of your finger.

Meet the Extension Kit from tado°

The Extension Kit connects your tado° Smart Heating Thermostat to your boiler if there is no cable for a thermostat from your boiler to your living room. The Extension Kit consists of the Extension Box, the cable to connect it to the boiler and plugs for different boilers. If you have a programmer attached to your boiler to control hot water production, the Extension Kit can replace it. This way tado° controls your hot water production too. The Extension Box fits the UK standard backplate, so it's easy to attach and you can easily replace the programmer without doing any rewiring.
