Best Smart Thermostat for Alexa

Installing a smart thermostat is the perfect way to ensure that you always feel comfortable at home.

And if the device is compatible with Alexa and Google Assistant, that’s the cherry on the cake! Alexa-compatible smart thermostats are taking the market by storm with their utility and ease of use. So, if you are building a smart home, these devices are a must-have.

That said, you are bound to get confused when deciding on the best option for your home ecosystem. So, to help you make the best choice, we conducted extensive research and came up with the top six options to try. You will also find a buyer’s guide that will help you understand what to look for when investing in an Alexa-compatible smart thermostat. 

So, let’s take a look!

Can Smart Thermostats Connect To Alexa?

Most major thermostat brands design their products in a way that they can be connected to Alexa and your home HVAC system. And rest assured, all of the products that we will be mentioning in this article can integrate with Alexa without any problem. 

That said, once you have connected the thermostat to Alexa, these are the benefits that you can enjoy:

Firstly, you can take an update about the current temperature in your room by simply asking Alexa. You can then use your voice to adjust the temperature according to your requirements. And if your thermostat is connected to the water line, you can even ask Alexa to turn the water heater on/off.

With certain thermostats, you also have the liberty to ask Alexa to change the temperatures of particular rooms. Now, not all smart thermostats come with the scheduling feature, but the ones that do can help you create a personalised schedule. This will automatically alter the temperature in the room right after you wake up in the morning or enter the house.

If you are on the lookout for smart thermostats to add to an existing home ecosystem, we suggest that you give this product a try. The product design is simple and ensures convenience as it adjusts the temperature depending on whether or not someone is home. 

Pros

  • Stellar design
  • Offers zonal control
  • Prevents heat wastage
  • Complete automatio

Cons

  • Subscription required to avail all features

Product Description

This is one of the best smart thermostats to invest in if you are looking for maximum utility at an affordable price. The design of this thermostat is pretty minimalist and will go with any modern home decor. And it can be used on its own without any extra radiator valves for zonal control. 

There’s no doubt that it works well with Alexa. But it is also compatible with a range of other voice assistants like Siri and Google Assistant. So, on installing the app, you can regulate the thermostat with your smartphone. We suggest that you set up heating routines to ensure that you enjoy maximum comfort. And with its simple voice control feature, you can regulate this device and save energy. 

Moreover, this device comes with an open window detection feature. To ensure that heating and cooling are optimal, the temperature sensor automatically detects when you leave a window open. The auto assist feature further detects when no one is home and turns down the temperature if needed. 

That said, some of the features that Tado offers are inaccessible without a paid subscription. So, do keep that in mind before making the purchase. 


2. Hive– Works Well With Hot Water

Hive 851816 Thermostat for Heating and Hot Water control (conventional boilers) with Hub
  • Hive Active Heating - get 10% off thermostat installation with Local Heroes
  • Heating and Hot Water schedules – set up to 6 daily time slots
  • Heating and Hot Water Boost – for up to six hours

The Hive thermostat is a great option for anyone who wants to enjoy being able to control their home heating remotely. It comes with a multi-zone feature and can regulate the hot water system in your home. 

Pros

Cons

Product Description

Hive brings you essential features that enable you to set a personalised heating routine. There are six individual slots that you can make use of throughout the day to easily adjust the temperature according to your needs. This is a great way to save energy and will help you cut down on your bills. 

The other thing that caught our attention was the geofencing feature. Since the thermostat app is connected to your phone, it can detect when you are not home. So, in case you leave home without turning off the thermostat, you will immediately get smart alerts on your smartphone. This will help ensure that there is no waste of electricity. 

Also, this device will help you deal better with frozen pipes. During the winter months, it is common for pipes to freeze and develop frost and that is when Hive’s frost protection feature can be of help. The moment the outside temperature drops below 7 degrees Celsius, this feature gets activated, thereby preventing any frost development in the pipes. 

To enjoy all the features and make the most of this device, we recommend that you get it installed professionally. Unless you are a trained electrician, your DIY skills might not be enough to get this device installed properly. This is one of those smart thermostats that needs to be handled with care.

You won’t need to hire a professional technician for the job. 

Additionally, this is one of the latest smart thermostats that enables you to control the temperatures in different rooms separately. For this, you will have to install the smart radiator valves that come along with the package. These valves are pretty easy to install, nothing that you cannot handle with relevant DIY skills.

To make the most of this smart thermostat, we suggest you spend some time navigating the app and learning about its features. You can use the Wiser Heat app to control your home heating along with the hot water system. When it comes to moderating your home heating or cooling system, there’s nothing this thermostat cannot do. 

However impressive the features are, just like all other products, this one too comes with certain downsides. It is not the best in terms of design and the room temperature is not displayed directly on the display. And if you want to adjust the temperature, you will need your smartphone for this purpose. Manual operation using the screen is not possible on this device.

You would also be happy to know that apart from Alexa and Google Home, this thermostat is compatible with IFTTT too. 

Furthermore, the device is equipped with the intuitive geofencing technology, which is extremely useful when it comes to saving energy. Because of this feature, the thermostat quickly understands when you are not home. 

The app tracks the movement of your smartphone to understand where you are. And when you are just about to enter the house, the thermostat senses it and keeps your home at the perfect temperature. 


Buyer’s Guide

Before purchasing, you should always test smart thermostats to see if they match your requirements. That said, it is no doubt a challenging task, and you will need to keep a few factors in mind while making the decision. 

It is essential that the smart thermostat you choose is not just Alexa-compatible but also fulfils other essential criteria. Wondering what they are? Let’s take a quick look!

1. Customer Reviews

To understand whether an option is good or not, you need to check whether the smart thermostat offers more than just the essential features. And to figure that out, there’s nothing better than customer feedback. If you have difficulty choosing, always go for devices that most users love. 

Smart thermostats work 24×7 and are connected with other smart home devices. So, it is not unnatural if they malfunction sometimes. This is true even for top smart thermostats. And that is when you require good customer support from the manufacturer. But how do you know you are going to get that? Go through the customer reviews properly, and you will have your answers. 

Other than that, if a device is popular and has received thousands of positive reviews, chances are that you will love it too. We recommend that you avoid products with too many negative reviews. 

2. Features

Mostly the smart thermostats you see on the market are rated on the basis of the features they offer. The most sought-after features are room sensors and motion sensors, which help in cutting down on electricity bills. 

You can also look out for crucial features like geofencing, which helps a smart thermostat detect when you are home. If it detects you are outside, it will turn off the heating system and the hot water system (in case that’s connected with the thermostat). 

The other feature to look out for is scheduling. Most reputed smart thermostats offer the “scheduling/routines” feature that enables you to set a heating timer for a week or longer. 

This is a handy function that saves you the trouble of adjusting the heating and cooling system of your home every day. Once you set the schedule, the thermostat will automatically keep adjusting the temperature from when you wake up. 

Frequently Asked Questions

In this section, we are going to take a look at some of the most frequently asked questions about smart thermostats that are compatible with Alexa. 

Can Alexa run my thermostat fully?

Absolutely! Most of the reputed brands that make smart thermostats ensure that their product is completely compatible with Alexa. It means that once the device is integrated with Alexa, it can be fully controlled via voice commands. And the first step to making this happen is to download the Alexa app. 

Once that’s done, simply click on the device tab and select the “+” button on the upper right corner of the screen. After you have selected the thermostat category, browse through the list to choose the model you have purchased. This will help you add your thermostat to the Alexa ecosystem.

However, for certain smart thermostats, you will need to download a separate app to connect to Alexa. To check if that is required, visit the Alexa Skills Store. 

Just keep in mind that Alexa might fail to integrate with your smart thermostat in case your home wiring is not correct. That’s why we suggest that before you purchase an Alexa-compatible thermostat, get your electrical wiring at home checked by a professional. 

How much do Alexa-compatible thermostats cost?

The price range of Alexa-compatible thermostats varies greatly. With a bit of research, you will find that smart Alexa-compatible thermostats start from as low as $60. However, the chances are that the low-budget models won’t have a lot of features. If that’s not a problem for you, it is definitely a good start. 

For those who are new to adding smart home gadgets to their living space, these low-cost smart thermostats are a great bet. With time, you will understand your requirements better and will be able to invest in one that is multi-functional. 

You will surely have to spend a few extra bucks if you are looking for features like remote room sensors or temperature sensors. While the costlier variants might feel like a significant investment in the beginning, with time, you will see how they help you cut down on electrical consumption. 

Features like geofencing and scheduling help to moderate room temperature according to your lifestyle and requirements. And the amount you save on your electricity bills will surely compensate for the price of the product. 

Do smart thermostats require a c-wire to function?

Most smart thermostats require a source of power to function, and for that, you will need a c-wire. If you are replacing an older thermostat with a new one, there’s a good chance that you will find a c-wire already present. In that case, you will not need to buy the adaptor separately. 

If you cannot find a c-wire, do not lose heart! You can easily opt for thermostats that run on batteries. Older thermostats mostly did not require c-wires as their power consumption was significantly less. However, for newer smart thermostats, the power consumption is much higher, which results in the need for c-wires. 

Final Words

After doing a deep dive into the whole range of Alexa-compatible smart thermostats, we picked the best six for you and reviewed them. And we hope that you now have better clarity about what to look for and how to choose the best one for your home. 

Apart from the ones we reviewed, there are a few others that deserve special mention, like the Ecobee smart thermostat and the Wyze smart thermostat. We suggest that you check them out as well. That said, just like everyone, we too have our top pick. Tado remains our all-time favourite for its functionality on all fronts. 

A small tip: make a list of your requirements first and landing on the perfect buy will be as quick and simple.

Until next time. Ciao!
