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, that can be accessed through the Amazon Echoand 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:
C-wire but can be bypassed by the power extender kit
If you don’t have a c-wire (common wire) in your heating and cooling system yet you have set your sights on a thermostat that requires one, simply get one of these EZWire adapters or the Fast-Stat Common Maker that provide the common wire even for multiple connections!
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 unrivalled 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 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.
The main difference between the Ecobee3 and Ecobee4 is the inclusion of Alexa in the latter. However, this doesn’t mean that the Ecobee3 doesn’t work with Alexa. It does, but only if you have the Amazon Echo device, which is sold separately.
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 doesn’t have one.
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.
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 have heated to your preferred temperature.
The main difference between the Nest thermostat and Ecobee4 is that the Nest actually learns your schedule and attempts to replicate it while the Ecobee adjusts according to a pre-entered schedule. However, the Ecobee definitely edges the Nest Learning thermostat not just because of the built-in Alexa feature, but also because of the remote sensors that allow different rooms to be heated separately only when they are occupied.
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
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.
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 Honeywell RTH9580WF is rated among the best smart thermostats in the market for plenty of reasons. It’s simplicity and ease of use make it ideal for anybody. You will also enjoy getting the current indoor and outdoor temperature readings right on the screen. When you pair it with Alexa, you can use a number of voice commands to control heating and cooling from wherever you are.

Emerson has a history of making reliable thermostats and they don’t disappoint with the Emerson Sensi Smart UP500W. Although the interface might look dated than the recent models of smart thermostats, it is clean and works exceptionally well. Its Wi-Fi connections disconnect sometimes and this spoils an otherwise incredible experience. At its price, there are not many bad things you can say about this thermostat.
Last year, 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.
It understands voice commands pretty well, even if you’ve got that strong Deep South accent! Tell it to lower the temperatures to a desired setting or by a desired number of degrees and it will do exactly that in a few seconds.
Installation is easy and it is even easier to connect it to the Amazon Echo via its Android or iOS app. Just make sure your Wi-Fi connectivity is working well.
You can control the thermostat even if you are away from home
It has a flawless geo-fencing feature that enables it to know when you have left or coming back home. It will then know whether to turn on or off.
It is cheaper than most smart thermostats
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.
Emerging from the shadows of the disaster that came in the form of the Lyric Round is not easy, but the Honeywell Lyric T5 is built to do exactly that. From the design to functionality and price, it beats its predecessor in every way possible. In addition, it can be paired with Alexa to give you enhanced control while making your home smarter.

Why Should I Use Amazon Alexa
With the emergence of Google Assistant and Apple HomeKit, there is a huge competition brewing up as far as voice assistants are concerned. And this brings us to the question; why choose Alexa over the Google Assistant or Apple HomeKit?
Well, it is because this voice-controlled wireless speaker from Amazon is capable of much more than its competitors. Just by using the sound of your voice, Alexa can do a lot of things such as search the web, give instant weather reports, shop online, create a to-do list, control smart home features including bulbs, appliances, and thermostats, as well as read you news and sports headlines. All this can be done without pressing any button or sacrificing your comfort.
How to connect Alexa to your thermostat
Follow these steps to connect your thermostat to Alexa:
Connect the Amazon Echo to your Wi-Fi
Ensure that the Alexa Android or iOS app is working
Open the app and select Smart Home which is under the menu icon
Wait for it to discover your smart devices
Select your thermostat on the device links once it has been discovered
Tap on continue
Enter your thermostat’s login details
Wait for the app to link with the thermostat
Select discover devices
Your thermostat should appear on the list
As simple as that, now you can use voice commands for your thermostat.
Alexa Thermostat Commands You Can Use?
Alexa understands quite a number of voice commands for controlling your thermostat. They include:
Alexa commands to check the temperature
Alexa, what temperature is my “thermostat name” set to?
Alexa, what is the temperature in the house?
Alexa, what’s the temperature in the “thermostat name”
To set a specific temperature
Alexa, set the “thermostat name” temperature to X degrees
Alexa, change the “thermostat name” to X degrees
Alexa, turn my “thermostat name” to X degrees
To increase or decrease the temperature
Alexa, decrease the “thermostat name” temperature
Alexa, increase the “thermostat name” by X degrees
Alexa, make my “thermostat name” warmer by X degrees
Note that X in these instructions indicates whichever number you choose to say. In case you don’t mention any number, Alexa will reduce the thermostat by 2 degrees Fahrenheit or 1 degree Celsius. These instructions also vary with the kind of thermostat you have. For example, if you own the Ecobee4, you can tell it to read the news, check the weather, among other things besides just adjusting the temperatures.
It makes it easier for the elderly and visually impaired to adjust thermostats to their ideal settings.
You can custom-name your thermostat independently and control them through voice commands.
Newer models like the Ecobee4 can do way more including providing you with live weather readings as well as the news.
With the exception of the Ecobee4, you will have to purchase the Amazon Echo separately and the thermostat separately before pairing them.
According to research on the growth of the smart home market, it is projected that number of smart home systems will grow by 31.4 million by the end of the year. This trend has made manufacturers to focus on creating smart devices that take advantage of this growth. The Amazon Echo and Echo Dot are some of these devices designed to make your smart home experience better and simpler. Once you switch to voice commands for your thermostat and other devices and enjoy all these features it has to offer, you won’t turn back.
