How Do I Choose the Best Alexa Thermostat?

Thermostats are devices that signal your Heating Ventilation and Air Conditioning (HVAC) system to increase or reduce the temperature of your home according to your preference. This can bring you comfort and save on your energy bills. Gone are the days when you had to stand next to your thermostat and fiddle with it to configure the settings to suit you. There are now wireless enabled thermostats that you can control remotely using your smartphone or tablet.

The best Alexa thermostats are compatible with most existing heating and air conditioning systems. They are programmable and able to save you money by reducing your energy consumption. There are some thermostats that have humidity sensors, which work well with systems that have a dehumidifier installed. A lot of them have sleek designs and LCD touchscreens that let you interact with the thermostats.
There are lots of features that make Alexa thermostats different from each other. There are the big ones that almost all brands have, and there are small ones. The main thing that affects the pricing of Alexa thermostats is the amount of technology packed into them. It is normal that we all want the best product on offer with all the juicy options, but since that means a high cost, we have to make trade-offs that will fit a thermostat into our budgets.

A high-end Alexa thermostat with all the nice options usually costs about $250. Ones with fewer options that will still definitely save you some money in the long run will go for around $100. There are cheap Alexa thermostats, but they're a waste of time and resources. You do not want to buy a cheap thermostat, as it will start giving you issues from day one.
Whether you’re getting a thermostat upgrade or installing a new one, there are options you might want to consider before deciding on which Alexa thermostat to get. The following are features you should look for:
  • Compatibility
  • Programmability
  • Remote access
  • Energy saving
  • Remote sensors
  • Extras
This list will guide your decision on the features that you consider important in an Alexa thermostat. As you read on, you will learn how these features affect the usefulness of a thermostat.
Construction and Design
Most homes in the US use some form of Heating, Ventilation and Air Conditioning (HVAC) system. There are single, two-stage, and for heating systems, three-stage functions. When buying an Alexa thermostat, it is important to check that it is compatible with your already existing system. There are models of smart thermostats that are compatible with as many as four heat and three cool functions, so it shouldn’t be hard to find a thermostat that is compatible.

When you have determined which Alexa thermostat will work with your existing system, you can now start thinking of how to program it. The way to get the best result is to consider your lifestyle. Do you stay home at particular periods? What is the temperature of your location like? Does the house get empty at regular intervals? These are examples of questions you need to clarify to know your programming needs. The questions will vary widely, of course, depending on each individual. How you program your thermostat can significantly reduce your yearly energy costs, while you might notice no real difference if you don’t program it correctly. Most Alexa thermostats are easy and straightforward to program, with their user-friendly interfaces.

Lots of Alexa thermostat models can accommodate complex schedules that will suit even unpredictable lifestyles. There are some that will let you set a schedule from Monday to Friday, and then set a different plan for weekends. This is ideal for people who go out during the week and stay home for the weekend. Some other thermostats let you set your preferred options, but you can still make manual changes (perhaps if you have guests) and it will revert to your prior setting later. Some even go further by giving you the option to set multiple temperatures within a 24-hour time frame, while still having different programs for each day of the week. There is a particular brand that literally learns your preferred settings and saves it as a schedule you can continue using.

When remote sensing hardware is placed in a room, the thermostat detects the temperature of the room and adjusts it according to the ideal temperature you have set. That way you can adjust the temperature of different rooms in your home, rather than just the room where the thermostat is installed. Some remote sensing thermostats can actually tell when you’re home, so they can adjust the temperature according to your needs.
Performance and Ease of Use
One of the most critical factors to consider in the performance of Alexa thermostats is the energy saving feature. This is not just to save the environment (which is quite important) but to save money, by reducing energy consumption. Almost every brand that makes Alexa thermostats pays serious attention to the energy saving capacity. Programmable Alexa thermostats, and those models that learn your preference, can help you save a lot of money over time. There are some models that will even create reports that show you how much energy you’re consuming, and enlighten you on how you can manage the system better.

Most Alexa thermostats have remote access. Thermostats that are capable of remote access are Wi-Fi-enabled. You can use your smartphone, tablet, and sometimes a laptop to access an app associated with your thermostat and make any change you want. Remote access can also help you save energy cost in certain cases.

There are many other characteristics you will find on Alexa thermostats:
  • Auto change: There are some thermostats that auto-switch from cooling to heating and vice versa, which is especially useful for times where the weather changes sharply.

  • Touchscreens: These are the points of interaction between you and your thermostat. Some models have full-color screens. Most models have user-friendly interfaces and varying screen sizes.

  • Instant savings: Some thermostats calculate your savings as you adjust the temperature. Others notify you when you are using energy saving schedules.

  • Exterior temperature: Some Alexa thermostats display the current temperature on the outside, while others that will give you a forecast.

  • Filter and maintenance alerts: Some thermostats signal you as a reminder to change air filters and run maintenance for your system.

  • Humidity sensor: These sensors notify you of the humidity level in your home. This is especially ideal for homes that have dehumidifiers installed with their HVAC systems.
