7 Things to keep in mind when buying the best smart thermostat

While any thermostat can control your home’s central air conditioning and heating system, a smart thermostat lets you control your settings using your smartphone, smartwatch, smart speaker, computer, and in some cases, your TV’s voice-activated remote control. 

There are several things to consider when buying a smart thermostat, and these are some of the main ones we think you should keep in mind:

  1. Appearance:

Some designs blend in with the walls and surrounding decor, while others can’t miss a large display, and there are many designs that are boxy and lack elegance. Choose a design you like and accessible.

  1. Touchscreen:

While all smart thermostats have a display, not all of them come with a touchscreen, and even fewer have a color one. Some models have mild or corporal buttons. If you primarily plan to control the thermostat from your smartphone or use voice commands, a large and colorful touch screen may not be necessary for you. Choose a screen size that works for your room and usage and gives you a display that visually shows the information you want at any time.

  1. Compatibility:

Pretend your home’s air conditioning and warmth system is suitable for  a traditional thermostat, any of the best smart thermostats should work but check with the producer to ensure your HVAC situation isn’t out of the question. Also, some models require a C-Wire adapter for power, so again, check before buying. To maximize the “smart” capabilities of a smart thermostat, look for one that’s compatible with the equipment you already use.

  1. Online Capabilities:

A smart thermostat will connect to your home’s Wi-Fi and allow you to remotely control the device from anywhere in the world with your smartphone. You can issue voice commands to the thermostat using a smart speaker or the digital assistant built into your smart speaker, home hub, smartwatch or even your voice-controlled TV remote.

  1. Learning Capabilities:

Over time, the best smart thermostats will learn your daily routine, habits, and preferences and automatically adjust your home’s temperature, saving you money on your utility bills.

  1. Installation:

If you know what you’re doing and are comfortable using basic tools, you can install most of these smart thermostats in less than an hour, assuming you’re replacing an existing thermostat. However, many people find it easier to hire a licensed electrician to handle a smart thermostat installation and initial setup.  Using the website (or mobile app) for Thumbtack or Angi Services can help you quickly find a local, reputable electrician.

  1. Heating zones: 

Creating thermal zones enables you to have greater control over different parts of the home. This can either be done by using multiple thermostats – one up and one down, for example, or by investing in some smart thermostatic radiator valves that give you control over each room for potentially greater savings.

Our Top Pick

The Google Nest Learning Thermostat is our top pick. The Google Nest Learning Thermostat maintains your preferences so you can spend less time adjusting the temperature and get a smaller utility bill. You can simply tie the Nest to your home safety system or phone so it knows when you’re away and synthesizes the temperature consequently.


  1. Do smart thermostats still work without Wi-Fi?

Yes, smart thermostats work like traditional thermostats without Wi-Fi. You’ll be able to control the temperature from the panel, but all app-based functions will be unavailable until Wi-Fi is restored.

  1. Can I install a smart thermostat myself?

Yes, however, if you are not comfortable setting up new technology, it is better to spend money to have a professional and licensed electrician come to your home and handle the installation. 

If your home is already equipped with a C-wire to control an existing thermostat, however, you should be able to handle the installation yourself in 30 to 60 minutes.

  1. Are Smart Thermostats Worth It?

Decades ago, programmable thermostats revolutionized our home’s energy use by allowing us to schedule our heating and cooling. Smart thermostats have ushered in a new era where our thermostats do all the work for us, giving us convenience and energy savings. The best news is the best smart thermostats don’t cost much, and the energy savings usually pay off your investment in a few years.

  1. Do smart thermostats save money?

Absolutely. Smart thermostats can help you save money by increasing your energy efficiency at home (while you stay perfectly comfortable, of course). Controlling your thermostat from anywhere using your smartphone or tablet and energy-saving app features like scheduling and geofencing help you stop paying to heat or cool an empty home. In fact, Mysa customers have reported an average savings of up to 26% on their home electricity bills. Smart thermostats can help you save more money by using less energy.

  1. Can I get a thermostat with a camera?

We couldn’t find any wall thermostats with built-in cameras. However, the top three thermostat brands on our list also sell security cameras that you can incorporate into automation with their respective thermostats. Yes, even the Ecobee has a camera. 

For example, you can point a camera at the thermostat and ask it to record a 3-second clip to find out who is turning up the heat every time the temperature is manually adjusted.

Final Words

Smart thermostats have rapidly become one of our favorite smart home devices. With the capability to track, monitor, and synthesize temperature and other factors within your home, you have whole control at your fingertips. There are two big players when it comes to choosing the best smart thermostat for your smart home needs: Google Nest Learning and Ecobee Premium. They offer the most comprehensive feature set, robust and clean build, and reliable connectivity. Nest Learning is renowned for its new, energy-saving algorithms that track your usage patterns and adapt to lower your energy bill while predicting your preferred temperature. 

The Ecobee Premium is a little more all-encompassing as a smart home device. It has a microphone inside to pick up voice orders, which you can send to Alexa or Siri if you don’t have another smart speaker close. Additionally, it is compatible with Apple HomeKit, though not Google Nest. 

Therefore, we hope that our article helps you to know the best smart thermostat in the market. All the smart thermostats we listed above are currently the best-selling and top-rated smart thermostats in 2024. Make sure you choose only the listed thermostats to get the best product.
