Guide to HVAC and home automation device compatibility

Are you looking to get a smart speaker for your home? To get the most from your investment, it’s important to pick the one that can work with the smart devices you’ve already got, including your HVAC smart thermostat.

Similarly, if you already have a Google Home, Amazon Echo (with Alexa) or other smart speaker, you might be considering upgrading to a smart thermostat so you can adjust your comfort settings with simple voice commands.

It’s the ultimate in luxury for busy people who don’t want to interrupt what they’re doing to adjust home comfort settings. The problem is, figuring out which thermostats work with which smart speaker devices is not a simple task. Doing all that research can be confusing and time consuming.

That’s why we’ve put together this guide to HVAC and home automation. You’ll find helpful information about the top smart thermostats and their compatibility with the most popular smart speakers.

Smart speaker setup: how to connect a smart thermostat

Most smart thermostats communicate with smart speakers via “skills.” Each smart speaker brand has a library of skills that you can find online. Connecting the devices is a simple matter of downloading or enabling the skill (depending on the brand). As part of setting up the skill, you’ll learn the command word or phrase to control your thermostat with your smart speaker.

In no time at all, you’ll be ready to start controlling your home’s comfort settings with a simple spoken command.

Enjoy!
