Smart devices aren’t just smart because they can connect to the internet or tell you about the weather — the very best devices are designed to help you save money too.
Take the top-rated Google Nest Thermostat, for example. The smart thermostat can analyze your home's heating and cooling patterns and then adjust the ambient temp accordingly. In fact, it knows to keep it toasty when your family is home, and tone it down when it’s just you. It also automatically turns the heat down when you leave your home for the day.
Right now, you can get one for $97 at Amazon — that's $33 off! This thing is so popular, it's earned a five-star rating from more than 7,000 reviewers!
Amazon will give you free shipping too. But if you have Amazon Prime, you’ll get so much more — from access to new movies and TV shows and discounts at Whole Foods to exclusive deals and two-day shipping on many, many items. Not yet a member? Relax; you can sign up for a free 30-day trial here.
The Google Nest Thermostat also syncs with your smartphone via the Nest app. Now you can control the temperature of your home, even if you’re heading home from the store or just touched down at the airport. It’s even great if you’re in bed and just don’t want to get up to adjust the thermostat.
"...I love being in bed and turning it on from my phone, if necessary," shared a delighted five-star reviewer. "Or the heat will kick on when I pull into my driveway. It was very easy to set the program and adjust as I see fit. I think Google does an amazing job of simplifying instruction with quick-to-the-point walk-throughs."
Here's the payoff: All that precise, targeting temp-adjusting can lower your heating and cooling bill. Translation: It pays for itself in the long run (or maybe the not-so-long run). According to Nest, the Google Nest Thermostat can save you up to an average of 12 percent on a heating bill and up to 15 percent on cooling per year.
"...You can set a schedule on the app for what temp you want it set throughout the day and while you sleep," explained a satisfied Amazon shopper. "It geo-fences your location and will turn temp up when you leave the house if you want it to. It really is a must-have for busy people like my wife and I...The thermostat definitely has made a noticeable change on our electric bill and it is not difficult to use or set up. If you're on the fence, go for it, I did and I am so happy..."
"Absolutely love this and it looks amazing on the wall of my mid-century house," added another happy five-star reviewer. "It works flawlessly and I've had zero problems setting it up and using it. Wished I'd gotten one of these Nest devices years ago — it's a true game changer in my house. Very convenient to use versus the old one I had to get up and change all the time!"
