You can control the Tado smart thermostats via your smartphone. This way, you can arrange the temperature in your house even when you're not home. With the Tado smart thermostat knobs, you can set the temperature per space so the heating isn't on unnecessarily. Tado thermostats have extra energy-efficient options when you have a subscription. For example, the thermostat automatically goes down when your window is open. Do make sure that your heating system works with a Tado thermostat, like your boiler or hybrid heat pump.
