What's a smart thermostat?

A smart thermostat is a device that manages your heating and can be controlled by your phone, tablet or computer. It shows you how much energy you're using, monitors your use and also learns your routine, which means it'll start to turn on when you usually put the heating on.

It works by connecting to the internet and letting you set a heating schedule. Some smart thermostats can even turn themselves on as you're approaching home by tracking you with GPS.

What can it do for me?

A smart thermostat is a smart home essential. Along with smart lighting and an Amazon Echo, a smart thermostat – such as the Netatmo Smart Thermostat by Starck – gives a new level of control and allows you to manage your energy use.

No matter where you are, you can have complete control of your home’s temperature directly from your smartphone, tablet and computer. Because you can turn your heating on with your smart phone, you can make sure your heating is on when you're headed back from holiday or when you pop out unexpectedly and don't want the heating on while you're out.
