The Nest thermostat was created by former Apple engineers who designed iPodsTM and iPhonesTM. In true Apple style, the Nest interface exemplifies simplicity. To the user it appears like a simple dial thermostat: set it to a certain temperature and it stays there. But behind the scenes the Nest is anything but simple. If you manually adjust the temperature – say turning it down before going to work and turning it back up when you get home – the Nest will learn your habits and start to make the adjustments automatically. The Nest can connect to the Internet via your home WiFi. With a smartphone app, you can control the temperature remotely.
