Why does my nest thermostat keep going offline

Nest thermostats are an integral part of home automation, but just like any other electronic device, they are prone to issues such as WiFi getting disconnected or just showing offline.

The Nest devices allow the homeowners to control the temperature more efficiently and decrease their energy spending over time.

Most of the time, Nest thermostats work flawlessly, however, if you’re having any connection issues, then you can try to troubleshoot the unit by yourself.

Usually, the Nest thermostat fails to connect to the WiFi because of internet-related issues, battery problems, software or hardware issues with the device, etc. Common fixes such as resetting or rebooting the thermostat device may fix the problems right away.

Follow the troubleshooting tips and instructions listed below and see if you can make it work again.

Fix: Nest Thermostat Not Connecting to WiFi and Going Offline

Restart your thermostat

The first thing you should do is restart the thermostat and you can do it with just a few taps. Go to the Options in the menu, tap Settings and you should see the restart button. Tap it and then hit yes confirm.

Apart from the “restart” option, you should see a reset button as well. In many cases, a simple restart is sufficient to fix common problems. So, always try to fix the issues with a restart. If not, then you can do a reset.

Once the system has restarted completely, you may need to reconnect the Nest to the wireless network if it does not automatically do so.

Check your WiFi Internet connection

If your WiFi doesn’t work, then obviously the thermostat can’t connect to the network. So, you need to check your home WiFi internet and ensure that it actually works.

Inspect the router and make sure the cables are fully plugged in, the unit is powered on and the correct indicators are on. Then try to access some random apps or websites using your phone (while connected to the WiFi). Check with your ISP if there’s a local internet outage.

Restart the router

Many times the issues are solved by restarting the router which makes the Nest thermostat start the connection from the beginning.

It’s possible that the router is having trouble maintaining all the paired devices and by rebooting it you allow it to reestablish the pairings and automatically solve any network problems.

While every router is a little different, here are some general step-by-step instructions that work with the most common models:

• Unplug the router and the modem from the power outlet. Ensure all the lights are off.
• Wait at least 60 seconds, then plug the power cable back in.
• Usually, it will take a few minutes for the router to reboot. Once it’s on, you can try to reconnect your Nest thermostat to the WiFi.

If your home network uses Wi-Fi repeaters, then it’s recommended to reboot those as well. Unplug them from the power, wait 60 seconds and power them up again.

If the Nest thermostat still isn’t connecting to the WiFi, try the connection using your phone. If the phone doesn’t connect to the Wifi, you probably need to contact your internet provider to find out if there’s an issue with the service.

Reset the Nest device

The settings menu on the thermostat has a small setting icon that looks like a cog. If you select that option, the device will be reset.

Actually, this button will reset the network settings of the thermostat. Basically, it will erase all the network-saved information on the device and it allows you to start the setup fresh. If there were any issues with the network settings, then you can re-enter them from scratch and start over.

Follow the prompts and the unit and select your WiFi network (SSID), type the WiFi password, and then let the Nest unit connect to the network. In most cases just by doing this simple trick, you can easily fix the offline or connectivity issues on the Nest thermostat.

Move your router closer to the thermostat

Sometimes the distance between the router and the thermostat is simply too much. The devices will struggle to connect and the connection will randomly time. The farther away from the thermostat, the weaker the WiFi coverage will get.

A possible solution is by moving the router closer to the Nest thermostat and see if the unit connects easily to the WiFi. If moving the router is not an option for your situation, consider purchasing a Wi-Fi repeater that could help spread the existing signal farther away.

Check the thermostat’s battery

In some cases, the AAA batteries that are inside many Nest thermostats may expire or just go bad. That causes the unit to struggle to connect to the WiFi (since there’s not enough power juice to maintain the proper connection).

To fix this problem, you need to remove the thermostat from the wall, replace the two AAA batteries in the back and install it in its place. Other types of Nest thermostats use rechargeable batteries that can be recharged using a USB cable.

Keep your devices up-to-date

It’s recommended to always keep your devices updated to the latest versions. In many cases, the problems are caused by bugs in the built-in software or on the apps used to access the smart devices.

Ensure the Google Home app is updated. Check the Nest devices for any new software releases. Update all the apps and the phone software as well. Go to the settings of your app and check if there’s a new update available for download.

Conclusion

If your Nest thermostat shows offline or is not connecting to the WiFi, then you should try the suggestions listed above. Start by checking your internet status, then restart the unit, reboot the router, reset the network parameters, etc.

Keep trying and see if the thermostat is beach online. If still, you’re having issues, you may need to directly contact the Nest support team for further assistance.
