Best WiFi Thermostats to Try in 2021

If you haven’t yet changed out your old clunky boring thermostat in your home with a wireless digital thermostat – 2021 is the year to do it. Not only will it look so much cooler but it will also be far more effective at saving you hundreds of dollars over the course of the year.

To fully maximize those profits, you need total control over your thermostat. A wifi thermostat is the way to do that. But how to choose which one to put into your home? We are going to divide our recommendations into 3 categories:

• Top-Rated (as voted on by Amazon consumers)
• Cheapest Options – Best Smart/Wifi Thermostats Under $100
• Best-selling (as shown on Amazon)

I’ve found that when I am looking for tech that I’m not entirely comfortable with, looking at what thousands of other people recommend is very helpful.

Which One Of The Above Is The Best?

Google Nest Learning Thermostat Is The Hands-Down Best-Rated Smart Wifi Thermostat

However, it’s also twice as expensive as the next best option (the Emerson Sensi-Touch), which is also twice as expensive as the last option on our list (Emerson Sensi Wifi). If cost is a major concern, go with the Emerson product you can best afford.

What Features Make The Google Nest The Best-Rated Option?

• I love the idea of the little display “Google Leaf” which, when it’s visible, tells you that you’re literally saving energy (similar to the eco-setting on certain cars)
• Super easy to install – most folks report an installation time of less than 30 minutes
• There’s a smart feature called FarSight that will enable your thermostat to display time, temperature, or even the weather (outside, not in the room).
• Home/Away Assist knows when you leave home and then automatically adjusts itself to an Eco Temperature so you don’t heat or cool an empty home
• Energy History on the app can show you how much energy you used if you’re into that
• Quick View on the thermostat display will also show you Energy History
• Looking for even more detail on how the Nest works? Google has a handy details-rich site for you!

If you’re a consumer that loves tracking stats, figuring out exactly how to save every single dollar you can, or just loves to save money with the best smart/wifi thermostat on the market – choose the Nest!

What Are The Advantages Of A Wifi Thermostat In Your Home?

Save Money

Being able to adjust the thermostat savings on a daily basis (if you choose) may seem like a tedious way to save money but it all adds up at the end of the month and year.

There’s a great blog post that goes into the nitty gritty of smart thermostats and how they can save you money. There’s so much great detail in that post that I won’t repeat it here. Go read it over there.

However, think about the biggest ways you can save money with a smart thermostat:

• Programming the thermostat based on forecasted/current weather conditions; if you’re a “set it and forget it” person, you’re forcing your system to keep your house at temperatures that are wasteful and unnecessary when you’re not at home
• Controlling the thermostat via your phone can be the biggest way to save money (see below)

Remote Control

Have you ever arrived at work in the summer and realize that you left the A/C running at full blast at home? That’s a lot of wasted energy.

With a smart wifi thermostat you can access this device from your phone. In just a few seconds you can alter your home’s temperature settings. This allows a versatility in how you prepare your home for your arrival.

There’s little need to keep your home at a comfortable temperature when you’re not there. Need to work a few hours later at the office? Not a problem with a smart wifi thermostat. You can simply tell your system to delay changing the settings until closer to the time you’ll arrive home.

You’ve taken a vacation and get “stuck” out of town for a few extra days due to unforeseen circumstances? No problem! You can continue to keep your thermostat running at lower settings to prevent wasteful energy being used.

“Setting and forgetting” your thermostat settings will be a thing of the past. You will have total control of your home’s environment no matter where you are.

Monitors Your HVAC System

Most smart/wifi thermostats now can let you know when there are issues with your furnace/air conditioner. They can also notify you when it’s time to change or clean the filter.
