Top Smart Thermostats of 2024

In our continuous search for home automation excellence, we’ve tested and analyzed the market’s leading smart thermostats. Our selection criteria prioritize energy efficiency, ease of use, compatibility with home automation systems, and additional features that enhance user comfort and control. The smart thermostats listed below represent the cutting edge in climate control technology, designed to fit seamlessly into the modern home environment. Except for the Amazon thermostat, these smart thermostats work with Google Home and Home Assistant.

It’s easy to install a smart thermostat, but understand, most smart thermostats require a C-wire to function and older homes may not have access to one.

Top Choice That Won’t Break the Bank

We find that the ecobee3 Lite is a smart purchase because it blends comfort, economy, and ease of use into an elegant design. We may be biased because this is the brand we finally landed on personally, but we find the ecobee product line-up to be the best smart thermostats of 2024.

Similar with its basic functions to the ecobee Smart Thermostat Premium I installed in my own home, the installation was straightforward. The provided Power Extender Kit will be helpful for any owner with a C-wire-less system. The sleek touchscreen interface felt responsive and intuitive, making daily adjustments a breeze.

As with each of these smart thermostats, we particularly enjoy the convenience of adjusting our thermostat while away from home. The ecobee mobile app is not only functional, but it’s intuitive and has provided us with total climate control at our fingertips, ensuring a cozy return to our living space, regardless of where we are.

The potential for energy savings became clear as we analyzed the reports from the ecobee app. The ability for the thermostat to learn and adapt to our schedule contributed to a visible dip in our monthly bills, without compromising on comfort.

As a bonus, it integrates well with our current smart home setup – working seamlessly with Alexa and Google Assistant retrofitting our residence with the additional SmartSensors around different rooms allowed temperature balance throughout our living space, especially in previously problematic areas.

While we had to budget for the separate purchase of SmartSensors to maximize thermostat efficiency, we think the initial investment will pay off with the customized comfort and cost savings over time.

PROS:

  • Noticeable energy cost savings
  • Effortless control via mobile devices
  • SmartSensor compatible for room-specific comfort

We find the Amazon Smart Thermostat to be a savvy investment for those looking to save on energy bills without skimping on modern-day convenience.

We immediately took to the intuitive interface. Its sleek design blended seamlessly with our living space and the touch buttons responded precisely to our adjustments. We noticed how the thermostat adapted to our daily routines, thanks to Alexa’s programming, delivering the right temperature when we’d normally be reaching for the controls.

The impact on our energy usage became apparent within the first billing cycle. Comparing previous costs, this device was making good on its promise to trim our bills. Checking for rebates via the email from Amazon brought us a surprise for our wallet, enhancing the value of our purchase.

Controlling the thermostat while we were away was effortless for us. We easily controlled the thermostat settings with a few taps in the Alexa app, ensuring our return was greeted with the preferred warmth. It gave us peace of mind knowing we could manage our home’s climate from anywhere.

Easily installed, we saw Amazon Smart Thermostat’s solid performance first-hand straight away. It’s a solid choice for anyone seeking a cost-effective way to modernize their heating and cooling system.

Keep an eye out for Amazon deals; they often put this on a promotion, and while the price alone is a huge draw, no one loses when you can save money on a smart thermostat.

  • Notable savings on energy bills with the rebate opportunities
  • Straightforward installation process with helpful app guidance

Energy Star Certified

Having integrated the Sensi Touch Smart Thermostat into our daily routine for testing, we’ve experienced firsthand the convenience it offers. From installation to ongoing interaction, the thermostat’s user-friendly design stands out. It starts with the app-guided installation—clear, step-by-step instructions had us up and running in less than 30 minutes. There’s no need for painting or patching the wall due to its standard size.

We recommend the Sensi Touch Smart Thermostat for its ease-of-use and energy savings, making it a valuable addition to any smart home.

Using the device day-to-day is a breeze. Adjusting the temperature from the couch or even while away from home is one joy of a smart thermostat, and Sensi Touch delivers on this count. Sensors are accurate and respond quickly to any adjustments made via the app. Scheduled heating and cooling have definitely impacted our energy bill, confirming the device’s promise of around 23% savings on HVAC energy usage.

The integration with smart home ecosystems like Amazon Alexa and Google Assistant fits seamlessly into our lifestyle. We’ve found that being able to voice control the temperature adds a layer of convenience we didn’t know we needed. Despite its advantages, we had to ensure that our HVAC system was compatible with the C-wire requirement—so double-checking your system’s compatibility is vital. While using the thermostat, we’ve occasionally felt the touchscreen could be more responsive. However, this minor inconvenience is overshadowed by the comfort and control the Sensi Touch adds to our home.

PROS:

  • Effortless installation and setup
  • Seamless smart home integration
  • Attractive energy savings potential

 

CONS:

  • C-wire is necessary for operation
  • Some may find the touchscreen less responsive

Low Cost/High Features Energy Star Certified

The Honeywell Home T5 immediately impressed us with its straightforward installation process. Its sleek design fits unobtrusively onto any wall, blending into the decor rather than demanding attention. Programming our week’s heating schedule was a breeze—the intuitive interface allowed us to tailor our home environment precisely to our liking, minute by minute. While not as visually appealing as some of the other smart thermostats on this list, that’s certainly not a deal breaker since not everyone cares about that.

We believe the Honeywell Home T5 is a solid choice for those seeking a balance of energy savings and comfort control from their smart home setup.

Energy efficiency is a strong point of the T5. We observed noticeable savings on our utility bills from the get-go. The geofencing feature, which adjusts the temperature when the house is empty, is nothing short of smart living embodied. Comfort returned just as we did, thanks to the thermostat’s ability to learn our patterns.

However, it’s not all smooth sailing. Establishing a stable connection with our Wi-Fi network took a few tries. When it did work, the connectivity enriched our experience, letting us control it from anywhere via our smartphones. Worth noting, you’ll have to purchase a separate C-wire adapter if your home isn’t equipped with one, which is something you might need to consider.

The Honeywell Home T5 stands out as a competent contender for its feature to cost value. It does falter occasionally—with occasional app glitches—but these setbacks don’t overshadow the convenience and control it can bring into your everyday life.

PROS:

  • Adjusts to your schedule, ensuring consistent comfort
  • Potential savings on your energy bill with smart features
  • Compatible with major smart home systems for seamless integration


CONS:

  • Requires a C-wire for installation, which may not be present in all homes
  • Users report occasional Wi-Fi connectivity issues
  • Some find the app and setup could be more intuitive

Our experience with the Honeywell Home Smart Color Thermostat was positive. Its customizable color touchscreen is not only a joy to look at, but also quite intuitive to interact with when at home. We’ve found it delightful to tweak the screen color to fit various moods or seasons.

Remote access through the app has proven to be a game-changer. We’ve enjoyed being able to adjust our home’s temperature from anywhere, ensuring it’s always comfortable upon arrival. Its compatibility with major smart home assistants adds convenience, seamlessly integrating with our existing smart home ecosystem.

The Smart Response technology is impressive, learning our daily routine and making sure the house is always at the preferred temperature without us lifting a finger. It’s a feature that seems to understand us more as time goes on, anticipating our needs effectively.

However, the requirement for a C-wire installation could be a stumbling block for some homes, causing additional setup steps or even a call to a professional. It’s a good idea to check your current thermostat wiring before purchasing. Those with electric baseboard heating will have to look for alternative smart thermostat options, as this one is not compatible.

In terms of setup, tech-savvy individuals will likely have no trouble, but others may find the process and plethora of options overwhelming. Luckily, once over this hurdle, the day-to-day operation is as smooth as possible.

Our hands-on experience positions the Honeywell Home Smart Color Thermostat as a solid choice, provided your home meets the requirements. It’s a cleverly designed piece of technology that’s much more than just a pretty interface.

PROS:

  • Vibrant color display that’s customizable to match your decor
  • Ability to control the thermostat remotely with a user-friendly app
  • Smart Response technology learns your heating and cooling cycles for optimal temperature

CONS:

  • Requires a C-wire, which might not be present in all homes
  • Not compatible with electric baseboard heat (120-240V)
  • Setup process can be tricky for those less tech-inclined
