Nest Thermostat Won’t Connect to App: How to Fix [2023]

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.

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

If your Nest Thermostat won't connect to the app, check the internet connection and connect to a 2.4GHz WiFi band during setup. Update 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

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 can't 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.

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

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.

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.

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.

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. A factory reset could also fix Nest Thermostat  Error N260 and E294.

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

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, and 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 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!
