Are you cognizant of the fact that, according to data from the Environmental Protection Agency, heating and cooling systems account for about 53% of a home's energy consumption? This suggests that minor modifications to your HVAC system could result in substantial savings. Alexa thermostats, with their distinctive features such as personalized scheduling, auto-off during idle times, and user-friendly voice command functionality, are designed to improve energy conservation and cut costs.

I've had an Alexa thermostat for years (namely the Nest Learning Stat), and I can't recommend smart HVAC controls enough! They've definitely helped me and my family save money over the long term.

Other than the Ecobee4, you will need an Alexa-enabled device to control your system. For example: an Echo Speaker, Echo Show or Fire TV.

A C-Wire is generally required for smart thermostats to maintain a Wi-Fi connection.

What is an Alexa Thermostat?

An Alexa thermostat is a smart device that connects to your home's heating or cooling system and can be controlled using voice commands via Amazon's virtual assistant, Alexa. Some devices like the Ecobee have Alexa built-in while others need to be communicated with via an Echo speaker.

How to Choose the Best Alexa Thermostat for Your Home

There are a few factors you should consider before deciding on a smart thermostat. In this section, I'll go over some key decision factors and considerations to help you choose the right Alexa thermostat for your home.


The first thing you need to consider is compatibility. Not all Alexa thermostats work with all HVAC systems, so you'll need to verify that the model you're interested in is compatible with your current system. While most HVAC systems are usually supported, hydronic and millivolt systems have patchy compatibility.


Different Alexa thermostats come with different features. Make sure to consider the features you need before making your final decision. Some models come with features like geofencing, dynamic schedules, HVAC health reporting, and remote temperature control, while others may come with built-in sensors to adjust the temperature based on your family's daily routine.


Smart thermostats can be quite pricey, so it's important to consider the price when making your decision. Make sure to choose a model that fits within your budget. Also, consider if you need to have it professionally installed and if you need to run new wiring to the stat as that’ll add more to the final cost.


While it may not be the most important consideration, the design of your Alexa thermostat is still something to keep in mind. A lot of thermostats are in prominent positions in the house, so you'll want to choose a model that fits in with your home's decor and looks good on the wall!

Warranty & Customer Support

When choosing a smart device like a thermostat, it's important to consider the brand's reputation. Some brands like Honeywell have been making heating controls for almost 100 years while others might be repackaging Chinese hardware with very little support when things go wrong.

Consider the warranty of the device along with the level of customer support offered by the manufacturer. You'll want to choose a company with a good reputation for customer service in case you encounter any issues or have questions about the product.

The Honeywell Home T9 WiFi Thermostat with Sensor allows you to adjust the temperature in specific rooms, saves energy by reacting to your schedule, and has a detection range of up to 200 ft.

Top Features
  • Allows placing sensors around the home to focus on specific rooms, set ideal temperatures, and humidity levels while saving energy.

Multiple Rooms 

The T9 Smart Thermostat has sensors you can place in different rooms so you can customize the temperature in each room. You can also set it up to automatically detect which rooms people are in so you can save energy by only heating or cooling the rooms you're using.

A big caveat here though. From my experience, your HVAC system needs to be setup for multiple zones for this to work – the thermostat can’t instruct the system to heat one room and not another unless it supports it!


Before buying a smart thermostat, you need to make sure it works with your home's heating and cooling system. The T9 works with different types of heating and cooling systems, like gas, oil, and electric. But it doesn't work with electric baseboard heat. You also need to check if your home needs a power adapter called a C-wire to connect the thermostat.


The Honeywell T9 Smart Thermostat has received a lot of positive feedback from users for its smart functionalities and ease of use. One user praised its integration with Alexa and Ring app, while many appreciated the smart temperature sensor which helps regulate the temperature better and equally across multiple rooms.
