Key Considerations Before Purchasing a Smart Thermostat

Smart thermostats are more complicated than smart outlets and smart light bulbs. Unlike such devices, thermostats need to be hooked up to your electric and connected to their proper Internet protocol throughout your house. From there, you should be able to control them remotely with your smartphone. Here are some things to consider before you make your move on a smart home thermostat.

1. Is it Compatible with Various Smart Devices?

Compatibility is important to consider before you buy, especially because your smart thermostat will not be easy to uninstall. If it does not connect well with your other smart devices like doorbell cameras, home alarm systems, smart locks, and home security systems, you may end up having to replace your smart WiFi thermostat again. This could cost you.

You should also just make sure your smart thermostat's communication protocol is compatible with other smart devices. Read through our buyer's guide to smart home hubs for more information on this.

2. How Much Does it Cost?

Most smart thermostats may cost anywhere from $100 to $300, but they may also save you money in the long run. Smart home thermostats save money by conserving energy. They do so with features that allow them to detect your presence and adjust temperatures in each room accordingly.

According to, you can save at least 10 percent each year on energy by switching to a programmable smart WiFi thermostat. A separate study from Ecobee said their customers saved about 23 percent on heating and cooling in 2013, according to Global News.

3. Do I Need a C-wire for Installation?

Installing your smart thermostat should be as easy as possible. If you're not sure what to do, most smart thermostat companies offer tutorials and detailed installation instructions. Some even offer professional installation and warranties for an added fee.

If you want to do it on your own, one thing to consider is whether or not your smart thermostat of choice requires a C-wire to run correctly. C-wire stands for common wire, but it's not that common. It is a low-voltage wire that allows your heating and cooling system to receive constant power.

Many houses are run with four wires, which don't usually include a C-wire. If your smart thermostat requires a lot of power to stay running, you may need to install a C-wire to keep it going. This will certainly make the installation process a little longer and tougher than it otherwise could be.

4. Is There Reliable Customer Support?

If you're worried about the installation process, make sure your smart thermostat company of choice is known for exceptional customer service. If not, who are you going to call when you have a problem? There have been reports of reliability issues with some smart thermostats in the past. You need to make sure there is an expert to speak to if you're going to risk the money to buy a smart thermostat.

Smart vs Traditional Thermostats

Traditional thermostats do not offer the same convenient, energy efficient capabilities as the best smart home thermostats. You can benefit greatly from upgrading to a smart thermostat with these essential features:

Thermostat with Remote Sensor or Geofencing

Geofencing will let you set boundaries. Every time you come in or out of those boundaries, your thermostats will know about it. The best smart thermostats are able to use sensors, geofencing, or both to track which room of the house you're in and check whether you're home or away.

These smart WiFi thermostats can then lower and raise the heat in every room accordingly. Ultimately, a smart thermostat will save you money on electric by allowing you to use less energy each month. This is also good for the environment, helping to reduce greenhouse gasses your household emits.

Smartphone App Control

The remote aspect means you can control your smart home thermostat straight from your smartphone from anywhere you have WiFi. As a result, you can turn your temperature up when the kids are coming home or control it while you're on vacation.

Energy Monitoring

Many smart home thermostats will even let you monitor your energy usage via their remote iOS or Android app. This way, you can see what times and days you use the most and least energy and fix any problems.

Your traditional thermostat simply is not capable of these features. You cannot come home to find your traditional thermostat has adjusted the temperature perfectly for you. Traditional thermostats also can't create extensive schedules for every day of the week or lower the temperature when no one's home. If you're looking for an upgrade, one of the best smart thermostats will be perfect for you.


I carried out diligent research on every vital smart thermostat feature and comparison to come up with this list of the five best smart thermostats. As a result, I have found that installation, reliability, and certain features are the most important factors to consider when opting for a smart home thermostat. After all, if you can't install it or keep it connected and it doesn't have advanced features, it's no different than a traditional thermostat.

Throughout this process, I examined smart thermostats including GoControl Smart Thermostat, Vine Smart Thermostat, iDevices Smart Thermostat, Lux Smart Thermostat, and First Alert Smart Thermostat.

Overall, the Nest Smart Home Thermostat takes first place for best smart WiFi thermostat on the market. It has come out with multiple generations of its heating/cooling system and its customers are continuously content with its updates. For example, it now has a sleek design, adapts to your schedule, and uses motion sensors to determine what the temperature needs to be.

The Nest Smart WiFi Thermostat is also reliable and will track your energy for you. You'll have no problems with installation, especially since the Nest Smart Thermostat doesn't usually require a C-wire to stay powered on. If you're looking for a modern, energy-saving thermostat with all of the bells and whistles, the Nest Smart Thermostat is for you.


In the end, smart thermostats are for those who want to save energy and have control over their home's temperature from anywhere in the world. They have certain unique features you just can't find in a traditional thermostat.

According to Navigant Research Global Market Analysis, smart thermostats and associated software generated $1.1 billion in global revenue in 2016. This number is expected to rise to $4.4 billion by 2025. Look out for the next big smart home thermostats in the years to come.
