Are All Honeywell Thermostats Compatible with Google Home?

Extensive compatability with their smart and Wi-Fi models

Most Honeywell thermostats, especially the smart models with Wi-Fi and mobile app compatibility can link up with Google Home. 

So if you’ve got a Smart Thermostat or EvoHome setup that can be controlled via the Honeywell Home or Total Connect Comfort mobile apps, you’re in luck.

However, when setting up your thermostat with Google Home, you should verify if Google can control individual zones or only manage them as a single room within the app.

Because of this complexity, individual zones might not respond and you might have to group them together in Google Home.

Sample Voice Commands to Remotely Control Your Honeywell Thermostat

Connecting your Honeywell thermostat to Google Home simplifies climate control by letting you manage the temperature through voice commands.

To control your Honeywell thermostat with Google Home, you can use the following voice commands:

  • Hey Google, Make it warmer/cooler
  • Ok Google, Raise/lower the temperature by 3 degrees,
  • Ok Google, Set the temperature to 74”
  • Hey Google, Turn on the heat/cooling
  • Ok Google, Turn the thermostat to heat/cool mode
  • Ok Google, Set the heat to 69
  • Ok Google, Set the AC to 69

  • Hey Google, What’s the temperature inside?


Setting up your Honeywell Smart Thermostat with Google Home is a pretty straightforward process as long as you have a compatible smart thermostat and both apps downloaded. 

So even though the Honeywell mobile apps already offer smart functionality, you can extend it even further by including your thermostat in Google Home, opening up voice commands and routines.

    Ken, are you able to use the honeywell app to access and control your thermostat? Assuming you’re using an Android smartphone, this has to be working 1st, before you can control the t-stat using the phone’s google assistant.
    You have to complete the honeywell account set up and the t-stat has to be registered to your honeywell account, to control the t-stat via wifi/internet.

    My Honeywell thermostat works fine using “OK/Hey Google” commands from my Android smart phone.
    You must install then go into Google Home select “+” in upper left corner, “Set Up Device”, “Works With Google”, scroll down to and select “Honeywell Total Connect Comfort US” and follow the instructions, you must select the device and assign it a room in the home.
