Connecting Google Home Speaker to Honeywell Smart Thermostats




We bought a Google Home smart speaker with the Google virtual assistant, and were pleased to learn today, that Google Home now supports connecting our Honeywell  Total Connect Comfort (TCC)  thermostat.  We checked under the smart home devices option in the Google Home App.  Honeywell is now listed there,  and it found our home thermostat we scanned for smart devices on our home network.  No problems entering our TCC account into Google Home.  We’ll detail how that’s done below.

Google Home abilities for Honeywell’s collection of IoT devices is awesome, as it allows  you to issue voice commands through that intelligent speaker, to control the thermostat, and read out its current status as well as the indoor temperature readings.  Currently, the functionality seems a bit basic; you can read and set the current temperature on the thermostat.  But that’s all.  We’re hoping more functions for furnace control and status checking (like filter and furnace maintenance reminders) will appear soon.  We’re now going to run through how setting up this link works, now that they have developed it.

Since we’ve owned the Honeywell RTH9580WF internet enabled thermostat, pictured next, for a year or so now, we’ve already set up an account at the TCC website. Thus, we won’t describe how to do that here, as account setup over there is easy to achieve by following the instructions at the TCC web site.  However, a TCC account is required by Google Home, as it is for the Amazon Echo Dot for example, in order to control your Honeywell TCC devices.  So, set one up, if you do not have one already.

We also assume that you’ve installed and set up your Google Home smart speaker with the Google Home App on your tablet computer.

Locate the Honeywell Total Connect Comfort Ability

1. Sign up for a Total Connect Comfort account.  To get started, you’ll need a TCC account.  So, as mentioned above, if you don’t already have one, head on over to the Honeywell portal website here, and create one.  Be sure to save your user Id and password, as you’ll need this information when configuring the Alexa Honeywell TCC ability below.

2. Run the Google Home app on your tablet.  We’re using an iPad Air computer tablet in this scenario.  This app is located on page three of our iPad’s home screen, although yours may appear in a different location, depending on how many apps you have installed as well as how you might have arranged them.

If you see your thermostat listed, then all is finished, and you can no begin speaking commands to Google Home. Some of the commands that might work follow in the next section.

 

18.  You’re done!

Example Google Home Commands for Controlling Honeywell Thermostats

  • Okay Google, raise thermostat temperature.   Raises thermostat setting by several degrees.
  • Okay Google, raise thermostat temperature five degrees.   Raises thermostat setting by exactly five degrees.
  • Hey Google, lower thermostat temperature.  Lowers thermostat temperature setting by several degrees.
  • Hey Google, lower thermostat temperature four degrees.  Lowers thermostat temperature setting by precisely four degrees.
  • Okay Google, set thermostat temperature to 74 degrees.  Sets thermostat
  • temperature to 74 degrees.
  • Okay Google, what’s the current temperature inside?   She then speaks the thermostat’s current (indoor) temperature reading.

Note that the Honeywell TCC ability on Google Home appears to not currently support questions that ask for some status aspects of the thermostats (humidity, current program settings, status of furnace fan, et al).  We hope that such questions can be asked of Google Home in subsequent releases of the Honeywell ability.  Any ability offering should be able to respond appropriately to the following questions.

  • Okay Google, what is the current thermostat indoor humidity? 
  • Okay Google, is furnace fan on?
  • Okay Google, read the thermostat program schedule.

We’re happy to see this initial Honeywell ability on Google Home, which hopefully, will improve and expand rapidly.
