The Nest Thermostat is a pretty, intelligent little gadget that learns from your heating and cooling habits and, using sensors to know whether you’re home or not, and a Wi-Fi connection to get up-to-date weather information, programs itself to help you save energy and money.
You can also pre-set a heating and cooling schedule and even control the device via a Web, iOS, and Android app.
I’ve had mine for about 8 months now and am very happy with it. It’s brought my electricity bill down, and the scheduling is particularly nice. I’ve had it bug out on me a couple of times, but the customer support team was great and helped me fix the issue within 10 – 15 minutes.
