As summer is coming in hot with high temperatures, it's important to have a system for regulating your home's climate and keeping you comfortable. If you're someone who values reducing your energy consumption (and costs), a smart thermostat can be your go-to smart home device as we head into the season.

In a limited-time deal running today, June 4, at Amazon, you can get the Amazon Smart Thermostat for $16 off, bringing the price down 20% from $79.99 to $63.99. We saw this price back in April. If you missed out then, today presents a smart opportunity to buy.

When you install the Amazon Smart Thermostat (which requires C-wiring), you gain the ability to control your home's temperature directly from your phone, no matter where you are. You can also connect to Alexa-enabled devices within your home so you can use voice commands to instantly cool things off without even getting off the couch.

You can program the thermostat to automatically adjust itself throughout the day, saving energy when you're not home, and establishing your favorite temperature when you are. In the long run, the U.S. Environmental Protection Agency estimates that this thermostat can save you $50 per year on your energy bills.
