Summer inevitably brings two things: scorching hot days, and outrageous energy bills. But you can ease the sting from those extra electricity charges by investing in a smart thermostat that automatically raises your home's temperature when you're not there, and lowers it when you are. We recommend the Nest Learning 3rd Generation Thermostat, which is currently over $50 off on Amazon.
The Nest does more than your average programmable thermostat. For the first week following installation, you tell the device what temperatures you prefer and when you prefer them through the device itself or through a smartphone app. It starts to pick up on your routines so it can automatically turn the A/C (or in the winter, the heat) up when you're home and down when you're not. It can even sense when you leave your house using sensors and your phone's location to automatically switch into "away" mode, saving you even more energy. It's why we named it one of our favorite 4 greenest gadgets for the home that save money–and the planet.
After that first week, the Nest will do its job with no more input from you, so you can choose to ignore it—but you probably won't want to. The Nest automatically senses when you walk into the room, and displays the time, temperature, or weather. Plus, the Nest app tracks your energy use over time and suggests more eco-friendly temperatures, helping you become more energy efficient (and save more money).
The third-generation Nest usually retails for around $250 and rarely goes on sale, but right now, it’s $198 on Amazon and at other select retailers. The deal ends July 8.
