Who This Is For

Any household hoping to reduce energy consumption and utility costs would be wise to invest in a smart thermostat. However, they also offer some convenience and may improve the comfort level in your house over time.

What is a smart thermostat?

Smart thermostats are Wi-Fi thermostats that may be used with home automation and are in charge of managing a home’s heating, ventilation, and air conditioning. They carry out similar tasks to a programmed thermostat in that they enable the user to regulate the temperature of their home using a schedule, but they also include extra capabilities, including sensors and Wi-Fi connectivity, that address the drawbacks of programmable thermostats.

They share a Wi-Fi network with other Wi-Fi thermostats to connect to the internet. Other internet-connected devices, such as laptops or smartphones, can be used to change the heating settings. This feature is crucial to ensuring energy savings because studies have shown that households with programmable thermostats consume more energy than those with simple thermostats because homeowners either configure them improperly or entirely disable them. Additionally, smart thermostats log the temperatures inside and outside, and the duration of time the HVAC system has been working, and they can alert the user when the air filter in the system needs to be changed. On a later date, a device with internet access, like a smartphone, will normally display this information.

Benefits of a smart thermostat (in comparison to a standard manual one)

The days of turning a dial on a manual thermostat are gradually being replaced by the era of programmable and smart thermostats. Manufacturers have been competing to make some of the most advanced thermostats in recent years. They make regulating the temperature in your home quicker, easier, and ultimately substantially less expensive than using a manual thermostat. But how do smart thermostats give households access to these advantages?

In contrast to manual thermostats, programmable thermostats let you plan ahead to set various temperatures for your environment. By setting up your home to cool while you’re away and warm up right before you get back, you may be able to save money on your utility bills. Programmable thermostats are not always considered smart thermostats, though. A thermostat must use automated technology to lower human error and increase energy efficiency for the space in which it is situated before it can be deemed “smart.” Other benefits include:

  • Reducing the potential for human mistakes associated with manual and programmable thermostats.
  • Requiring less manual labor than typical thermostats to maintain and run.
  • More energy expense savings than manual or conventional programmable thermostats.
  • Increasing the market value of your house as they are well-known examples of smart home technology.

Why You Should Trust Us

Working with trustworthy independent writers with years of expertise in writing about lifestyle topics and product evaluations is something National Today takes great pride in. We have devoted numerous hours to testing various smart home appliances, such as smart smoke detectors, smart sprinkler controllers, smart garage door openers, and smart thermostats. We’ve tested smart thermostats and other smart-home technology all over our space for years.

How We Picked

Energy-efficient

Smart thermostats naturally conserve energy, especially when they take the place of older, non-programmable models. All of our recommendations, with the exception of the Mysa, have Energy Star certification from the Environmental Protection Agency. This indicates that their ability to save energy has been independently confirmed. According to Ecobee, compared to having a thermostat set at a constant temperature of 72 degrees Fahrenheit, consumers may anticipate saving up to 26% on heating and cooling costs. Mysa also asserts savings of 26%. Google Nest promises to reduce your annual HVAC costs by between 25% and 27% by saving you 10% to 12% on heating and 15% on cooling.

Display

A stylish touch display with a vibrant color scheme makes it simple to operate and configure the thermostat and can usually be seen from across the room. While more expensive devices have motion sensors that immediately turn on the display when you enter the room, more affordable ones just show the current time and temperature until you press the screen, at which point they frequently display the temperature and menu settings. Some models will also display your local weather forecast.

Easy to use

The latest smart thermostats enable voice commands from Google Assistant, Apple Siri, and Amazon Alexa, enabling you to use your voice to adjust temperature settings and check the current temperature. You can ask some of the most feature-rich smart thermostats out there to play music, get the most recent news and sports scores, check out the weather forecast, modify the temperature settings, and much more using Alexa voice control, which is built right into these devices.

Intuitive controls

Temperature changes should be automatically triggered by the thermostat system using algorithms, geofencing, or accessories like remote sensors. For instance, geofencing is a cool feature that creates a virtual boundary for your home. Your smart thermostat can change its settings when it detects your departure or arrival from the house as you cross the boundary. Some advanced smart thermostats use self-learning mechanisms that use movement detectors to “see” which areas of a house are occupied and when. They create a customized temperature plan for your home after studying your preferences.

Price vs. quality

The most basic models are still equipped with Wi-Fi radios that let you connect the device to your home network and the internet, despite being very affordable. A mobile app can be used to control them from a mobile device, such as a smartphone or tablet, and some models also support online browser control. Note that lower-end models come with fewer functions, while more expensive models are either overkill or tailored to particular HVAC systems.

Compatibility

Models must work with popular smart-home systems. Additional smart devices may be controlled by your thermostat, and vice versa. For example, your thermostat may change the temperature or turn on based on your geotagged location. If you have a voice assistant, confirm that the thermostat is appropriate for it, and think about whether the voice commands work for you.

Range

The size of your home and whether certain rooms have a hard time reaching the optimal temperature are additional factors to take into account. If so, you might want to think about a model like the Ecobee that includes or supports a wireless sensor.

Multi-Room

You may exert more control over various areas of the house by setting up heat zones. One way to achieve this is to use multiple thermostats, such as one upstairs and one downstairs, or you may spend money on smart thermostatic radiator valves that let you manage the temperature in each room, potentially resulting in more savings.

Wired or Wireless

If your system has a C (common) wire, which is utilized to provide steady power to the thermostat, that is another thing to take into account. A C wire is necessary for nearly all smart thermostats in order for them to function; however, older homes with older heating systems typically do not have one since older thermostats did not need one. Some smart thermostats have a DIY power extender kit that you may use to power the appliance. Without a C wire, other devices can be fitted, but they will draw power from the furnace control circuits in order to keep the internal battery charged. Although this often functions without a problem, it has been known to trigger issues with some HVAC systems and even cycle on the system to steal power.

Temperature sensor

A temperature sensor provides input on the process’s temperature, which can be used to monitor or manage the process. They are positioned all over the house and function by detecting the temperature in various rooms and relaying that information to the primary thermostat. To maintain a comfortable temperature, your thermostat will then utilize the average reading.

Why It’s Great

With the Ecobee Smart Thermostat Premium, you get a multifunctional smart home thermostat that also doubles as an Alexa voice assistant, an air quality monitor, and a home security system. It is simple to install, worked well in tests, and adds a stylish touch to any space with its modern design. It also includes a remote room sensor and is compatible with several third-party platforms. Although it is the highest model in Ecobee's line, the end result is a product that looks premium and is worthy of its similarly premium price.

Potential Flaws

In addition to being expensive, Siri support requires Apple HomePod or HomePod mini to function. Moreover, the HVAC system's fan won't turn on when the air quality sensor is activated.

Other Features

The Ecobee Smart Thermostat Premium looks significantly nicer than previous iterations, is comparable to the Nest Learning Thermostat, and is even smarter on the inside. It has a zinc casing and a much larger touchscreen. It now includes an air quality sensor built in, allowing you to determine whether opening a window or turning on a fan is necessary. You may also view the week's weather prediction on the enormous display. A terrific feature is its remote sensors, which make it easier for you to manage the temperature throughout your entire home. The audio quality and microphone responsiveness are terrific, and it also features a built-in smart speaker. For Apple users, HomeKit integration is a nice feature. With a single swipe, you can access your thermostat settings directly from the Control Center on your iPhone, and Siri can be used to voice-command the Ecobee.

Although installation is simple, you might want to get professional assistance if your HVAC system is sophisticated. We spent roughly an hour installing everything—pairing four sensors, establishing Wi-Fi, and configuring three smart-home system integrations. Add an additional two hours or the cost of hiring an electrician or technician if you need to wire in the power extender kit.

Who It’s For

Anyone looking for a smart thermostat with simple controls that can understand your preferences, schedule, and lifestyle.

Why It’s Great

The third edition of the Nest Learning Thermostat hits the ideal combination between design and intelligence, making it the next best smart thermostat currently available. It has the greatest algorithms available, a great user interface, a simple setup process, and top-notch industrial design. Since it studies your routines and makes adjustments accordingly, your heating system will eventually be able to adapt to meet your needs without any further effort from you.

Potential Flaws

The Nest Learning Thermostat has mostly been criticized for its lack of zonal control, which means that even though you can digitally control your entire house, you still have to manually regulate each radiator. Also, it supports iOS and Apple Watch but does not offer a native Apple HomeKit connection.

Other Features

In contrast to the vast majority of rectangular or square touchscreens on the market, Google Nest stands out with its unusual "modern retro" circular design and full-color display. Additionally, compared to other smart thermostats, it has more finish options (approximately six). As long as your HVAC system is compatible, Nest's setup process is known for its simplicity. The Nest is designed to work with contemporary 5-wire furnaces with a C-wire; it may also function with an older 4-wire configuration, however, an electrician may be required. After installation, respond to several questions and connect it to your home's Wi-Fi network. Nest makes these adjustments automatically with little to no interaction from you over time as it learns your schedule and climate preferences. Because Google Nest is able to detect when you're away, it won't cool or heat a home that is vacant and can raise the temperature in preparation for your return.

It is integrated with the Google Nest ecosystem's Nest Cam, Nest Hub, smart speakers, and other compatible smart devices. To help the Nest system maintain a constant temperature throughout, you may also add up to six additional Nest remote sensors to monitor the temperature in additional rooms.

Who It’s For

Whoever already uses Alexa-compatible smart home device and wants to utilize a cheap smart thermostat to control it with voice commands through an Alexa-compatible smart speaker or home hub.

Why It’s Great

Amazon has the best budget smart thermostat because it is the least expensive and most advanced in its price range. This is especially true for houses where Alexa is the main voice assistant because it is incompatible with Google Assistant or Apple HomeKit. However, it does handle a variety of HVAC systems, and it gradually learns your arrivals and departures so that your home isn't heated or cooled when you're not there.

Potential Flaws

The absence of appropriate remote sensors is the one genuinely major letdown. You might be better off with a unit that supports remote sensors if you have an unevenly heated or cooled home.

Other Features

The Amazon Smart Thermostat functions flawlessly with the Alexa voice environment, but using voice commands requires an additional Amazon Echo smart speaker or home hub like the Echo Show. To use your smartphone and the Amazon Alexa app to manage the thermostat, you'll need a second device because the thermostat doesn't have a built-in microphone or speaker.

Temperature control components using Honeywell Home Thermostat Technology are housed inside this chic, white square chassis. Self-installation of the Smart Thermostat is possible, but make sure it's compatible before you buy. A C-wire power adapter is necessary for some HVAC systems. This three-button integrated thermostat is simple and stylish (Select Mode, Temperature Up, and Temperature Down). Although the Smart Thermostat includes manual scheduling through the app and employs "Alexa Hunches" for some limited automatic control, it lacks deep learning and automation compared to more expensive competitors.

Who It’s For

These thermostats, as opposed to the more typical central HVAC systems, are made for heaters like baseboard, radiant, fan-forced convector, and similar heaters. Mysa is one of the few companies producing smart thermostats for high-voltage heaters, including baseboard, fan-forced convector, and radiant ceiling models.

Why It’s Great

With the use of geofencing, scheduling, and a smart eco mode, the Mysa Smart Thermostat can help you conserve energy and money. Since it is a line-voltage smart thermostat, it is compatible with 120- or 240-volt electric baseboard heating, in contrast to all the other types we examined. It boasts user-friendly software, a straightforward design with a modest, dot-matrix-like display, and capacitive buttons, and it doesn't need a separate hub to connect to the internet.

Potential Flaws

The major catch is that you will need to replace every thermostat to make your entire heating system smart, which is incredibly expensive (though over time that up-front cost could be offset by energy-bill savings since electric baseboard heating is so much less energy-efficient than other systems). Additionally, it is more expensive, and since the heaters it is intended to manage are not centralized, you will need to purchase one for each room (or at least one for every room with a heater you wish to control).

Other Features

Provided the total load does not exceed 3,800 watts, you can wire the Mysa in its place if you currently have more than one heater that is regulated by the same thermostat. The product from Mysa stands out for its crisp white design, simple dot-matrix display, and capacitive touch-sensitive buttons. It is a visually appealing device with a high-tech vibe that isn't unduly distracting. How you link the Mysa to your heater is the main technical distinction between it and other smart thermostats. Even if you can install the Mysa by yourself, the multi-wire arrangement can be challenging and call for a licensed electrician. However, once installed, it is simply operated by its lovely lit display. The Mysa V2 device is 40% smaller than its predecessor, which means it will fit more snugly against your wall. It also incorporates touch-sensitive buttons with audio feedback and an adaptable display that can adjust to your lighting choices with sleep and awake mode.

Care and Maintenance

How to set up

Make sure your thermostat is compatible with your system and wiring before you start the project. To ensure that their products will function with your wiring, some manufacturers, such as Ecobee and Google Nest provide compatibility tools or checks online.

  • Check for compatibility: It’s crucial to confirm the voltage is suitable for your existing system before you start the smart thermostat installation process. The instruction booklet for most thermostats should make note of the voltage range for which they are suitable.
  • Turn the power off: It’s crucial to ensure the power is turned off because you’ll be working with electricity. Your heating and cooling system’s power should be turned off at the circuit breaker. Wait for the system to halt if it is already running. Adjust the temperature dramatically after that. You will know it is off if you don’t hear the air start to run.
  • Remove old thermostat: The current thermostat cover should be snapped off or unscrewed. To recall your old system setup, take a picture of the wiring.
  • Label wires: If your old thermostat was installed properly, identify each wire with a small sticker or colored tape. Then, using a screwdriver, remove the old thermostat backplate.
  • Remove the new thermostat: You’ll probably need to patch the wall unless your new thermostat is the same size and shape as the old one. Using a putty knife, spread the joint compound onto the wall. Dry off. After lightly sanding the area, paint it to match the color of the next wall. Dry off.
  • Connect the new thermostat: Each wire with a label should go into the corresponding connector. Until the wires click, push them in. Push all of the wires flat against the wall once they have been connected to provide space for the thermostat display plate.
  • Attach display plate: The backplate should be attached to the thermostat display plate. You ought to hear it fit snugly into place.
  • Program thermostat: At the circuit breaker, restore the electricity. After that, set the thermostat as directed by the manufacturer. A smart thermostat will learn your routines and connect with your smartphone, enabling you to change the temperature of your home whenever you want and saving you money on energy costs.

Setting timers or scheduled turn-ons/switch-offs

You’ll appreciate geofencing if you have ever left your HVAC on all day while you were gone. Simply put, this technology establishes a virtual border around your house. Your smart thermostat notifies your HVAC system when you cross the threshold that you are not at home, turning it off or placing it in “out of home” mode. If you are on your way home, for instance, the boundary will signal your HVAC to turn on and raise the interior temperature of your home to the desired level before you enter.

A few smart thermostats take things a step further by utilizing self-learning mechanisms that use movement detectors to “see” which areas of a house are occupied and when. They create a custom heating and cooling schedule for your home after “studying” what temperature you prefer in each area. They can also detect more movement inside the house. For instance, during a party, they may lower the temperature to accommodate an increasing crowd. After your visitors go, the smart thermostat will resume its regularly scheduled programming.
But there’s more: by keeping an eye on the weather, smart thermostats may even take into account seasonal variations. When a heat wave is forecast, it will cool your house more or heat it more.

Do smart thermometers use more electricity?

Your ability to save energy can be significantly increased by installing a good smart thermostat. The ecobee smart thermostat, for example, can actually cut energy costs by up to 23%. This can result in annual savings of several hundred dollars. For homes, smart thermostats are convenient.
