Best Smart Thermostat

The cost of living is pretty high these days, especially when it comes to heating or cooling your home. Reducing your consumption is a great way to save on energy costs, but that’s not always easy to do. A smart thermostat is one way to make it easier, and can save you between 15 and 20 percent on your home heating and cooling bills.

Smart thermostats are designed to do all the work for you. Just program the optimum temperature inside your home and the smart thermostat ensures that it stays that way. You can also set a schedule that changes the temperature depending upon if you are home or not. And the beauty of it all is that you can also control it all remotely using an app on your smart phone, tablet or computer.

Not all smart thermostats offer the same options and features. It takes a bit of research to know which model fits into your lifestyle and needs.

We feature four smart thermostats you can purchase online. Read on to see which one is right for you.

Or, you can use the Quick View option on the display of the thermostat to see the energy history, settings or your schedule.

Things to look out for:

Smart thermostats are a great way to save money on energy bills for your home. Some have many more features than just controlling your home’s temperature. What you decide to choose really comes down to your personal preference and lifestyle. To help you choose, here are some of the more popular features and things to consider.


With all smart thermostats, you can link to the thermostat using a smartphone app. In some cases, the app lets you create a geofence. This acts as an electronic boundary that senses when you are home. It will adjust the thermostat to your comfortable setting when you approach your home and switch the thermostat to an energy-saving setting when you leave. This way, your home’s heating and cooling is adjusted to lower levels when no one is home.


Some of the more expensive, feature-rich smart thermostats have an alert to tell you if the temperature changes in your home when you are away. For example, if the temperature drops below freezing, the pipes in your home can burst, causing a flood. A warning from a smart thermostat alert gives you or a friend the time to go home and check for problems, averting a potential disaster, or in some cases, you can remotely change the temperature using a smartphone app.

Other alerts available with some smart thermostats include reminders to change the air filter or humidifier pad, send you temperature change notifications and internet connection alerts.

Remote temperature adjustment:

Sometimes, especially during very hot or very cold days, you want to come home to rooms that are warmer or colder than normal. Some smart thermostats make it possible to adjust the temperature before you arrive home with the use of an app on your phone or computer.

Color touch screen:

It’s a good idea to choose a smart thermostat with a large display color screen in order to easily read and manage the temperature in your home. If it has a proximity sensor, that’s a bonus so you don’t have to stumble around in the dark if you need to access the thermostat during the night. A proximity sensor will dim when you walk away from the dashboard and light up again when you are within range.

Installation and compatibility:

Before choosing a model, make sure you understand the installation requirements. Many are easy to install, especially for DYIers and the technologically savvy. Find out if you need extra power requirements and if your internet connection is strong enough to establish a wireless connection with other smart devices.

Some smart thermostats use battery power, which means you need to remember to replace them. Dead batteries mean your thermostat will not work. Other models use a C-wire, which delivers continuous power for operating the Wi-Fi.

Finally, make sure the smart thermostat you choose is compatible with your HVAC system.

Tech support

Not everyone is a tech wizard and no matter how easy the installation, programming and use instructions are, it’s possible that you will have some difficulties. Make sure the model you choose has good tech support, either through an app, video, website, direct communication through a telephone conversation or ideally, all of these options.
