Nest Thermostat Won’t Connect to App: How to Fix [2022]

Recently I splurged on a Nest Thermostat for my smart home, only for the device to straight out refuse to connect with my Google Home app.

Despite my primary smart home application being Google Home, I even tried to connect with the Nest app but to no avail

Triggered by this, I asked around for advice from Nest Thermostat users only to realize that this issue is actually more common than I initially expected.

So I figured I should make this troubleshooting guide based on how I fixed my Nest Thermostat not connecting to the Google Home or Nest app.

To fix a Nest Thermostat that won't connect to the app, check the internet connection and connect to a 2.4GHz WiFi band during setup. You can also try updating the Nest Thermostat firmware and the Google Home or Nest App. If the issue persists, reboot the Nest Thermostat. If none of these work, factory reset the Nest Thermostat.

Below I will explain the various troubleshooting tips so that you can fix your Nest Thermostat that won't connect to the app.

Check the Internet Connection

Check The Internet Connection

Before placing the blame on Nest, it is imperative to first check whether the root cause of the issue is from your end, specifically from the internet end.

If the Google Home or Nest app doesn't connect with the Nest Thermostat, it is possible the issue emerged due to an unstable internet connection, or lack thereof.

A fix for this is quite simple- just try connecting other devices to your WiFi and check whether the internet connection is properly working.

If you cant access the internet from other devices, check the router for any warning signals from your Internet Service Provider (ISP). Contact your ISP if that is the case.

If you can access the internet, then it is safe to say it is not an internet issue. But there is also another factor that comes into play in this case.

A deep search into forums brought forward a weird issue that isn't talked about a lot during troubleshooting and that is the use of dual-band WiFi.

Newer WiFi routers come with a feature called dual-band WiFi, which sends out two WiFi signals- 2.4GHz and 5GHz signals- for better connectivity features

The 2.4GHz WiFi band provides wider coverage at the cost of bandwidth speeds, while the 5GHz WiFi band provides faster speeds at a more restricted coverage.

Apparently, the initial setup of Google Home devices works best on 2.4GHz WiFi bands. Many have faced setup issues while on the 5GHz band.

So at least during setup, connect your Nest Thermostat to the 2.4GHz band WiFi signal if you have a dual-band WiFi router.

In fact, it is best to keep it connected to the 2.4GHz band as the Nest Thermostat has no need for the faster speeds of the 5GHz band, and could well utilize the extra coverage.

Update the Nest or Google Home App

Update The Nest or Google Home App

Despite Google not officially acknowledging that such an issue of the Nest Thermostat not connecting to the Google Home or Nest app exists, app updates can unintentionally help.

There have been cases where Google has silently fixed issues without causing any major uproar and this can possibly be such a case too.

Simply make sure the Google Home or Nest app is properly updated to the latest version from an official play store like Google Play Store or Apple App Store.

In order to update your Google Home or Nest app, simply follow the following steps:

  • Visit the application store on your smartphone or tablet. Depending on the operating system of your device, it should be Google Play Store or Apple App Store.
  • Click on the search button at the top of the store home page.
  • Search for Google Home or Nest and click on the first relevant result
  • This takes you to the Google Home app or Nest app's official application store page.
  • Look for the update option and click on update to update your application
  • If there is no update option, then you are probably already on the latest update.

This updates your Google Home app or Nest app to the latest firmware.

Reboot Your Nest Thermostat

Reboot Your Nest Thermostat

A reboot might seem like a rudimentary troubleshooting step to perform, considering the weight of the issue at hand. But it is a process that works nonetheless.

A reboot can help clear out any temporary bugs that might be plaguing the system, hence potentially washing out the issue and refreshing the system on the whole.

That being said, there are two types of reboots that need to be performed in order to achieve the best results: a software reboot and a hardware reboot.

A software reboot is similar to every other reboot that is used in the conventional sense, in that it is a restart of the software operating system inside the Nest Thermostat.

In order to perform a software reboot on your Nest Thermostat, simply follow the following steps:

  • Open the Quick View menu on your Nest Thermostat by pressing the thermostat ring
  • Click on the Settings gear
  • Navigate to the reset option and press select
  • Tap on Restart

This initiates the restart or software reboot process for the Nest Thermostat.

A hardware reboot or a power cycle focuses on restarting the charge inside the internal components of the Nest Thermostat, clearing any uneven charge inside the unit.

In order to perform a hardware reboot on your Nest Thermostat, simply follow the following steps:

  • Unplug the Nest Thermostat from the power
  • Let it sit idle for a minute unplugged
  • During the minute wait, press the buttons on the Nest Thermostat to get rid of any remaining charge
  • Plug the Nest Thermostat back to power
  • Let it sit idle for a minute plugged in

This completely reboots the hardware of the Nest Thermostat, getting rid of any uneven charges in the system.

Factory Reset Your Nest Thermostat

Factory Reset Your Nest Thermostat

If none of the above steps work for you, then the only option left is to perform a proper factory reset on your Nest Thermostat.

A factory reset will clear off all the user data on your Nest Thermostat, along with any bugs that may have existed in the system causing the pairing issue.

In order to perform a factory reset on your Nest Thermostat, simply follow the following steps:

  • Open the Quick View menu on your Nest Thermostat by pressing the thermostat ring
  • Click on the Settings gear
  • Tap on the Factory Restart option
  • Confirm the selection to begin the factory reset process

Do note that you will have to set the Nest Thermostat from scratch again, just like when you initially bought or unboxed the device.

Final Thoughts

Final Thoughts

Just like Wyze thermostats, Nest Thermostat is one of the most popular smart thermostats in the market currently, with many users implementing it for their internal thermal systems.

But smart tech still being in its infancy stage, bugs such as the Nest Thermostat not connecting to the Google Home app or Nest app are to be expected.

But despite this, the fact that these issues can be easily fixed from the user end is what makes the Nest Thermostat so popular, compared to its competition.

I hope my troubleshooting article on the Nest Thermostat not connecting to the Google Home app or the Nest app has been a good read and helped you with the same.

Have a good day!
