The Nest Learning Thermostat has been at the top of the smart thermostat game for a while now, and our list is no exception. It's stylish, easy to install, and can save you cash on your energy bills by running your HVAC in standby mode when you're not home. Whether you're using the device on the wall or the Nest app on your phone, adjusting the temperature and thermostat settings is straightforward and intuitive.
You can easily tie the Nest to your home security system or phone so it knows when you're away and adjusts the temperature based on your preferences. The Nest also has a built-in "Farsight" motion sensor and will light up the customizable display when it senses someone in the room, even if you're 10 feet away. The Nest is more expensive than the other smart thermostats on our list, but we think it's worth the higher price tag.
