Smart Thermostat Shopping Guide:



If you've ever received your energy bill and practically fainted when you saw the charges, you are not alone. Controlling the temperature of your living space is one of the biggest expenses that come with owning a home. Nobody wants to live in a house that feels like a freezer (or an oven). Sometimes the easiest thing to do is to set your thermostat to the perfect temperature and forget about re-setting it.

Unfortunately, this can be draining not only on energy resources but on your pocketbook. Luckily, technology has a solution for this—smart thermostats. Smart thermostats connect with other smart devices to manage your HVAC (heating, ventilating and air conditioning) system. Utilizing apps, smart thermostats can be programmed to perform a variety of functions. With smart thermostat technologies becoming more and more advanced by the minute, you can even turn your heater on from far away which means you'll never have to come home to an icebox again, and your energy bill doesn’t have to suffer for the luxury.



Smart Thermostat Compatibility

When it comes to smart thermostats, it is important to first verify that your HVAC system can accommodate the technology; luckily, most do. Typically, you will need a Wi-Fi connection so the smart thermostat can use the internet to communicate with the thermostat itself. To do this, most utilize a C-wire (or a common wire). If your system doesn't already have one of these, you might need to buy an adapter kit.

Choosing a smart thermostat that is compatible with the device you plan to use (for example, an iOS or Android smart phone) might outweigh a lot of other considerations. The majority of smart thermostats are useable with both platforms, but it is always wise to double check!



How You Will Use Your Smart Thermostat



When selecting a smart thermostat, consider which specific tasks you want it to perform. Do you want to keep the heater/cooler off during the day while you are away at work, but have the system kick in just before your arrival at home? Or, do you want a smart thermostat that will learn your temperature settings and automatically adjust to suit them?

On the whole, smart thermostats tend to have at least the basic following functions:

  • Scheduled Heating and Cooling
  • Using smart thermostat apps, you can schedule your heating and cooling systems to turn on and off at specific times of the day, saving precious energy for those hours nobody is at home.

  • Learned Scheduling
  • Some smart thermostats utilize algorithms to learn your schedule. In time, you may not even need to adjust the thermostat at all.

  • Home/Away Mode
  • Some smart thermostats can detect when you are home and raise or lower the temperature accordingly. Watch for the word “geofencing” in product descriptions as this feature utilizes distance settings to detect when your connected device is in range. For example, you can set your AC to turn on or off if your smart phone moves a certain distance toward or away from the smart thermostat.

  • Heating and Cooling Based on Occupancy
  • Taking Home/Away mode one step further, in some thermostats, remote sensors (rather than a signal from your connected smart device) utilize motion and proximity to sense if you are home. In addition, with these types of sensors installed in multiple rooms, your smart thermostat can automatically control temperature based on individual room occupancy, keeping occupied rooms at a comfortable temperature while saving energy in empty rooms.



Smart Thermostat Design & Style

Thermostats aren’t considered the most desirable home good in terms of interior design. If you are wandering down the thermostat aisle at the local home improvement store you might notice that the traditional models all look much the same; they are usually pasty gray and very utilitarian.

This is another reason homeowners love their smart thermostats—unlike the average bland designs that are meant to blend into your wall, smart thermostats were created to be stylish. With minimalist designs and digital screens, today’s latest smart thermostat designs are considered quite fashionable. From silver to black and round to square, you are sure to find a design that speaks to you.



Other Considerations When Choosing Your Smart Thermostat


  • Smart Home Integration Features
  • Beyond the basic integration of your smart thermostat with your smart phone, you can integrate many smart thermostats with larger smart home systems such as Apple HomeKit, Amazon Alexa, and Google Assistant.

  • Smart Thermostat Remote Access
  • Remote access allows you to access your thermostat from afar, so long as you are connected to the internet (you don’t have to be in range of your home Wi-Fi). Going home earlier than you thought? Simply use your app to make adjustments. You don’t have to wait for the house to heat up or cool down, it will be all ready to go once you get there.

  • High-Voltage Considerations
  • If your home is heated by high-voltage systems, you will need a smart thermostat to accommodate that as most are designed to work with the average HVAC system.

  • Energy Usage Reports
  • Many smart thermostats come with monthly reports that break down your energy usage history, even allowing you to chart your use from month to month. Many of these reports also come with tips and tricks for additional energy conservation.
