How To Make Nest Thermostat Discoverable

Nest Thermostat

Wouldn’t it be nice and fun if you’d check and control the temperature of your home right from your smartphone or tablet, or even better if you’d ask Amazon’s Alexa to set the temperature for you?

Well, you could be one of the happy smart homeowners enjoying all the great convenience of technology if you invested in a Nest thermostat and then connected it right to make it discoverable to your smart home voice assistant.

Keep in mind that whether you choose to use the Amazon Echo Show smart home hub or Google Home, your Nest Thermostat will still work.

But, why should you bother with a Nest thermostat, for example, the Nest Learning Thermostat, when the device is already pretty good at detecting temperature?

While this is true, you could enhance the precision of this thermostat if you incorporate an Amazon Echo hub and then give commands for temperature specificity using your Alexa voice assistant.

So, instead of walking up to the thermostat in the middle of the night to raise or lower the room’s temperature, you get Alexa to listen to do and do exactly what you want.

How to link your Nest thermostat with Alexa

For this setup and for the connection to be complete, you need your Nest Learning Thermostat and an Alexa-enabled device. Since the Alexa integration works with all the Nest thermostat models, you won’t have to worry about compatibility. You also need an Alexa-enabled device.

What this means is that you will need any other Amazon device besides Amazon Echo (which is the most popular Amazon device and also the device that most people think about when Alexa is mentioned), 2nd generation (or higher) Amazon Fire TV, Amazon Echo Dot, or Amazon Tap.

Note that the Amazon Tap and Fire TV voice assistant modes aren’t always on, and you’d have to tap the device for use. Remember that the Alexa-enabled device you choose would be the speaker responsible for the processing of all your voice commands to Alexa.

The other thing you should know is that you could choose to use the Amazon Alexa app or the Amazon shopping app since these two apps come with built-in Alexa voice assistant functions, and they can work over LTE networks, besides Wi-Fi.

Steps for making Nest Thermostat Discoverable

Test for compatibility

Before you do anything, you first need to make sure that your Nest Learning Thermostat is compatible with the existing thermostat wiring in your home. You could check for compatibility by yourself by looking at how the wires are held together.

To cut to the chase, your smart thermostat will not be compatible with your current wiring if, after removing the existing thermostat cover, you realize that you have some thick-stranded wires that are held in place (and together) with wire nuts. 

But the thermostat’s wiring may be compatible if you see two labels for the individual wires. We recommend checking the device’s compatibility before you buy your new smart thermostat.

Shut off power

After the confirmation of the device’s compatibility, the next step is to shut off the power to your HVAC system. This is a safety precaution.

Get to work

Now that you’ve completed the safety and the compatibility checks, it’s time for you to get to work (don’t be scared, it’s not an overly complex technical process). To ensure that the installation of the new thermostat is effortless, your Nest thermostat comes with everything you need for installation, including the screwdriver.

So, if yours is a home upgrade, you’ll need to remove the older thermostat, then attach your Nest base. Connect the wires then attach your Nest thermostat display.

But if you don’t trust yourself with the handiwork, you could get a technical professional to come and fix the thermostat. After you’ve installed the thermostat and powered it on, the next step will be to connect this smart thermostat to your home’s Wi-Fi network.

Once you’ve connected the thermostat to your home network, it will be ready for use, and you can manually adjust the temperature.

 Next Steps – Making Your Nest Device Discoverable

  • Download your Amazon Alexa app (if you don’t have it already).
  • Once you’re logged in, go to the Devices tab (looks like a home) located at the bottom-right corner.
  • Click on the Plus sign at the top-right corner and then select the Add Device option.
  • Choose the Nest thermostat, followed by the Google Nest option.
  • Now, download your Google Nest app then enable the Google Nest Skill (on the Google Nest App).
  • Next, log to your Google account and then allow your Alexa access to the Google Nest information. Note that if you have more than one Google Nest device installed, for example, a Nest security camera, then you need to share the information with Alexa in this step.
  • When done, give Alexa access to your Google Account and then click on Discover Devices.
  • In the next (last) step, pick your Nest Thermostat.


And just like that, your Nest thermostat is not only discoverable but also connected to Alexa. So, give it a test run – ‘Alexa, change the temperature to 78 degrees.’

  • Go to your Amazon Alexa app on your smartphone and then go to the menu section (the hamburger-like icon) at the corner.
  • Select the Smart Home option on the menu list and then choose the Smart Home Skills option at the bottom of your Smart Home Screen.
  • Next, click on the Enable Smart Home Skills tab then search for the Nest Thermostat.
  • Choose the skill you wish to enable and then click on enable.
  • Next up, you will need to provide your Nest account credentials, which you will use to link to your Alexa account. When all that is done, discover the Nest device. Device discover is easy – ask Alexa to work her magic “Alexa, Discover my Devices.’


Note: You must be the owner of the Nest thermostat you wish to set up the Nest-Alexa connection with. So, if you have shared access to the device, you will not be able to set up your Alexa-enabled devices to work with the Nest devices. 

Also, bear in mind that when it comes to the whole Alexa-Nest voice thing, you always have to mention the location of the Nest device you are trying to communicate with, which means that you must assign location to each Nest device in your home. So, don’t forget to use the exact location on each device’s name.
