Best Smart Thermostats That Work With Alexa
Life isn’t comfortable without a good thermostat.
However, getting up every time to set the thermostat to a preferred temperature is inconveniencing. In fact, it takes away some of the comfort and convenience that the thermostat is supposed to provide.
Not even the learning thermostat can tell exactly what kind of temperature would be ideal for you at a particular moment. This is mostly because of the daily minor weather changes that call for adjusting the thermostat by a couple of degrees from the temperature you would normally require.
In truth, there is no real smart thermostat that can conveniently adjust to your preferences based on the indoor weather conditions. This is why you need a thermostat with voice control. And Alexa, a voice control feature by Amazon, can be accessed through the Amazon Echo and the Echo Dot is the perfect voice companion for thermostat owners.
While there are many thermostats that can be paired with voice assistants, it becomes quite difficult to determine the best.
And if that is the reason you are here, then I am happy to tell you that I put in more than 70 hours on research and testing to determine the best thermostat to pair with Alexa. I have shared my findings here and explicitly given reasons for the rankings.
Top 8 Alexa Compatible Thermostats
The following are the best thermostats that work with Amazon Alexa:

Ecobee4 –Best Alexa Integration Technology
The Ecobee4 is ideal for the shopper who is looking for powerful technology, beauty, and high performance embedded into one. What’s more exciting is that you don’t need to purchase Amazon Echo when you get the Ecobee4 thermostat.
If you have used the Ecobee3 or read our review on it, then you would know how powerful it is. Ecobee4 is even more powerful than its predecessor and has Alexa embedded in it so that you can tell your thermostat to do a wide range of things.
As the first smart thermostat to have Alexa embedded in it, Ecobee4 boasts of a variety of cutting-edge features and a performance that is unrivaled in the industry at present.
You don’t need to buy the Amazon Echo! Instead, expect to gets news headlines, music, and even weather updates amount others right from your thermostat!
Just like the Ecobee3, the Ecobee4 also comes with remote room sensors. These are tiny sensors that you place in different rooms to enable the thermostat to heat every room individually.
Picture this: a thermostat normally heats the whole house equally whenever it is switched on. Imagine the energy spent heating all those unoccupied rooms when you just needed heating in one room. Remote sensors eliminate this waste of energy by heating only rooms that are occupied. With this technology, you will save lots of money that could be spent on energy costs.
Pros
- With Alexa embedded, you will be more than happy to save about $100 that could have been spent to purchase the Amazon echo.
- You get to control the thermostat through voice. Besides you will enjoy other voice features like getting news updates, weather updates, sports, and so much more. You can turn Alexa on or off whenever you like.
- With room sensors, be prepared to cut your energy costs by more than 23%.
- Easy to set up and connect to Alexa
- It comes with a power extender kit which eliminates the need for a C-wire if your heating systems don’t have one.
Cons
- There is this blinking red light at the front-facing side of the thermostat that can’t be turned off. Although it isn’t that bright to distract your sleep, at least they could have added an option to remove it.
- It doesn’t support all the commands like the Amazon Echo and the Echo Dot. This is mostly because it is a pioneer of this integration and so I expect more commands to be added soon.
Normally, when looking for a thermostat that works with Alexa, you might have been thinking of something that only understands commands related to heating and cooling. While this describes many Alexa compatible thermostats, the Ecobee4 is in a league of its own.
If the other thermostats will follow suit remains to be seen but at present, given the benefits you will get from this feature-packed Ecobee4, it is safe to say this is the only Alexa controlled smart thermostat you will ever need.
Nest Learning Thermostat –Best Learning
If you already have Amazon Echo, then you probably don’t need another thermostat with Alexa embedded in it. In fact, the perfect choice for you would be the Nest Learning Thermostat.
Imagine having a thermostat that you could set and forget and then occasionally adjust the temperatures through Alexa without leaving your comfort zone.
With the Nest Learning Thermostat, you have a smart learning thermostat that utilizes the power of Alexa to make your home comfortable just the way you like it.
Its incredible features, beautiful looks, and an amazing performance coupled with a voice-control make it one of the best you can get –and that’s why I rate it highly.
What I like most about the Nest is that it will learn your schedule and replicate it exactly the way you want. However, there are days where the weather might change suddenly and you would need to raise or lower the temperature. This is where Alexa comes in. No matter where you are, simply say “Alexa, lower the temperature by 1 degree” and it will do exactly that!
In addition, it can detect when you are home or away and switches on or off automatically. In fact, this feature detects when you are about to get home and switches on the thermostat so by the time you enter the house, it has heated to your preferred temperature.
Pros
- The Nest integrates seamlessly with Alexa and supports essential commands you would ever need in a thermostat.
- It learns your schedule so that you wouldn’t have to adjust it at all times. This makes it way better than most programmable thermostats.
- Has intuitive Android and IOS apps to enable remote control. You will get to know temperatures at your home even when you are away from home.
- It is a proven energy saver that determines when you are home or not and uses the information to conserve energy.
- It is very easy to install but can only be used if you have a c-wire
Cons
- It is highly priced given that it comes at almost the same price as the Ecobee4 yet the Ecobee4 has Alexa embedded in it.
- It heats all rooms evenly, even those that aren’t occupied since it doesn’t come with remote sensors..
The Nest Learning Thermostat has been a leader in the smart thermostat niche and its integration with Amazon Alexa brings a whole new level to the way we interact with smart thermostats. Although it doesn’t have remote room sensors, hopefully, Nest will work to find a solution for heating and cooling each room separately. The combination of the features it provides and the voice commands provided by Alexa make it one of the best you can buy –and its quality assures you real value for money.
Honeywell RTH9580WF –Best Programmable
The Honeywell RTH9580WF may not get the top prize when it comes to the design.
However, with its large easily visible screen, an impressive range of features, and the amazing performance it gives when paired with Amazon’s Alexa, there is no doubt that it is the best programmable thermostat that works with Alexa.
The RTH9580WF gives you control over everything –starting with the screen color to remote monitoring and control through its Android or iPhone app. Its huge touchscreen is clearer than many high-end thermostats and enables you to see the current readings from a distance.
With it, you will enjoy advanced locking features and password protection to prevent unauthorized persons from interfering with your preferred settings.
Pros
- At its price, this is the best thermostat under $200 that works with Alexa
- It comes with a large easy-to-read and customizable touchscreen and you can easily change the screen color to match your home décor
- In addition to voice control, you can control this thermostat remotely through its Android and iOS apps
- You will get temperature alerts and reminders via the native thermostat app or through the manufacturer’s website.
- You will enjoy features such as an advanced level fan and comfort control as well as an indoor humidity sensor
Cons
- It requires a c-wire to install. However, you can purchase a power extender kit to draw power to the thermostat.
- Gets some problems with its Wi-Fi connectivity. However, I haven’t seen the problem is listed on many websites online so it might just be a minor defect on my thermostat.
Emerson Sensi Smart UP500W –Best Budget Thermostat
If your budget falls just below $100 yet you are in the market for the best smart thermostat that works with Alexa, then the Emerson Sensi Smart UP500W is the most ideal pick.
It may have thicker bezels than most thermostats on this list but it does perform a good job in excellent fashion –and even better when paired with Alexa through Amazon Echo or Echo Dot.
The Sensi boasts of the J.D. Power award for the Highest in Customer Satisfaction with the thermostat having been rated highly throughout the years. It may not have that beautiful glossy design like the Ecobee4 or the Nest, but Emerson made sure to compensate that with a great performance. However, this doesn’t mean that it has the worst looks that would mess your home décor.
To use Alexa, connect your UP500W to the internet, open the Alexa app, navigate to thermostats and wait until it is discovered. Tap on it and select your preferred settings. With these few simple steps, you will be ready to use voice commands on your thermostat.

Honeywell Lyric T5
A couple of years ago, I spent about $200 on the Honeywell Lyric Round. At first, it delivered a good performance but after a few months, it started turning on the heat when it was supposed to cool. I replaced the thing immediately after my electricity bills came in. This is why I was so skeptical about the Lyric T5. However, here is what I found out:
The Honeywell T5 is an improvement from the Lyric Round in design and performance. Surprisingly, it comes at almost $100 cheaper than its predecessor. Now you must be wondering what was sacrificed to make the T5 better –nothing! However, it is
It is neither the most beautiful thermostat in the market nor does it perform at the level of the top thermostats in this field, but it does outperform similar-priced competitors. It is quick to install but you have to remember that it needs a C-wire in order to work.
When paired with the Amazon Alexa, you’ll get to enjoy adjusting temperatures just by issuing voice commands. Remember the name you give your thermostat under smart devices on the Amazon Echo app since I have encountered friends who complained that this thermostat wasn’t working with Alexa only to find that they are using a different name to refer to it.
Pros
- It understands voice commands pretty well, even if you’ve got that strong Deep South accent! Tell it to lower the temperatures to the desired setting or by a desired number of degrees and it will do exactly that in a few seconds.

Cons
- You must have a c-wire in order to use the Lyric T5. If you don’t have one, make sure to purchase a power extender kit.
- It doesn’t have many features for the echo, except raising and lowering the temperatures.
Emerson Sensi ST75
The Emerson Sensi ST75 is one simple and useful thermostat that you will happily install in less than 10 minutes and take another 10 minutes to program.
While some thermostats complicate the installation process, you will get this Sensi up and running on the wall and on your phone in a few minutes. That’s not all! Pairing with Alexa is also simpler than you would think.

The look and feel of the Emerson Sensi ST75 is just awesome. The hardware is robust and durable which is a reminder of the qualities that made Emerson popular in the first place.

Whether you want to place it vertically or horizontally on the wall, the readings will adjust between landscape and portrait mode to give you a wonderful experience without taking up much space or messing up your home décor.
You don’t need plenty of bells and whistles just to set your thermostat and Lux understand this better.
