Nest Thermostat Keeps Going Offline: Troubleshooting & Fixes

There are a few possible reasons why your Nest thermostat keeps going offline. The most common reason is that the Nest is not connected to the internet. This can be due to several factors, including a weak Wi-Fi signal or an issue with your router.

If you suspect your Wi-Fi signal is the culprit, try moving your Nest closer to your router. If that doesn’t work, you may need to reconfigure your Wi-Fi network or invest in a more robust router.

Another potential reason for an offline Nest is an issue with the power supply. If batteries power your Nest, they may need to be replaced. 

If your Nest is connected to a wall outlet, ensure the outlet is working correctly and the power cord is firmly plugged in.

If you’ve ruled out Wi-Fi and power issues, the Nest may have something wrong. In this case, you must contact customer support for troubleshooting assistance.

Restarting your Nest Thermostat

First, try restarting your thermostat. To do this, simply remove the faceplate of your Nest and press the Nest logo for about 10 seconds until you see a green light. This will restart your thermostat and hopefully fix the issue.

If restarting your thermostat doesn’t work, check your Wi-Fi connection. Ensure your router is turned on without interference from other electronic devices. If you’re still having trouble, you can try resetting your router.

If none of these solutions works, there may be an issue with your Nest account. Try logging out of your account and then logging back in. You may need to create a new account if that doesn’t work.

Checking your Internet connection

If you use a wireless connection, try moving your router closer to the thermostat or connecting it via an Ethernet cable. 

If the issue persists, try restarting your router and modem. You can also try factory resetting your Nest thermostat

Remove the Nest from its base and press and hold the Nest’s button for about 10 seconds. If none of these solutions works, please get in touch with Nest customer support for further assistance.

Updating the firmware on your Nest Thermostat

If your Nest thermostat is offline more often than online, there’s a chance that the firmware needs to be updated. Although the process is pretty straightforward, there are a few things you need to keep in mind before starting.

First and foremost, make sure that your Nest thermostat is connected to Wi-Fi. If it’s not, the firmware update won’t be able to go through. 

Secondly, check the battery level of your thermostat. If it’s below 10%, the firmware update will fail. Lastly, remember that you’ll need the Nest app installed on your phone or tablet to update the firmware.

Now that you’ve checked all those things off the list, updating the firmware on your Nest thermostat is a piece of cake. 

Open the app and go to Settings > Thermostats > Firmware update. The process should only take a few minutes, and once it’s done, your thermostat should be back online and working like usual again.
