Nest App Shows Offline but Thermostat Is Online: How to Fix [2022]

After spending a lot of time setting up my new Nest Thermostat with my HVAC system, I noticed that the Nest app is detecting the device as offline even though it is clearly on.

I tried skimming through the manual to check if I had properly set up the Nest Thermostat, and I ended up wasting more time with little result.

So I went online and read through several user forums and Nest support pages. I was surprised to find that quite a number of Nest users were facing similar issues.

I compiled everything I learned into this troubleshooting article so that you can fix your Nest app if it displays an active Nest Thermostat as 'offline'.

If your Nest app shows offline even when the thermostat is online, check the hardware and the connectivity of the Nest thermostat. You could also try rebooting the thermostat. If none of the above works, perform a factory reset.

I have explained in detail the troubleshooting steps that can fix your Nest app if it is facing similar issues.

Check the Nest Thermostat Hardware

Check The Nest Thermostat Hardware

The Nest Thermostat is a smart home device that is meant to be attached to the wall for all its lifetime, and hence durability isn't considered a strong point.

It is not that it is a cheap product, but the priorities simply weigh much heavier on the smart features side of things rather than how much accidental damage it can take.

Therefore, it is important to care for the hardware of the Nest Thermostat and make sure it stays in tip-top condition for benefiting from its intended experience.

Do a proper check of the Nest Thermostat and see if there is any visible damage that might trigger a communication drop between the device and the Nest app.

If you notice any physical deformation, it is best to get it checked first preferably from an authorized Google or Nest service station.

As an added step, it is best to shift the location of any radio or electronic devices in the near vicinity of the Nest Thermostat as that can also trigger communication drops.

Check the Connectivity of Nest Thermostat

Check The Connectivity Of Nest Thermostat

Connectivity is an important factor when it comes to communication between the Nest Thermostat and your HVAC( Heating, Ventilation, and Air Conditioning) system.

Contrary to popular belief, even a wireless smart home HVAC monitoring system like the Nest Thermostat relies heavily on the wires that it connects to in the background.

The cables and wiring are the lifelines that connect the various components that allow for the communications to properly work.

Therefore, a single wiring error or physical wear can cripple the whole system and can lead to issues such as the Nest Thermostat not relaying its current status to the Nest app.

Check the wiring for any wear and tear. If there are any breaks or tears on the wires, swap the wires out. It is best to consult a Nest-certified technician to change wires.

Also, check if the internet connectivity is proper and up. The Nest Thermostat can show as offline on the Nest app if the device can't push the proper flag signal for the live status.

Make sure the WiFi is properly functioning and connected to the Nest Thermostat as well as the smartphone or tablet accessing the Nest app.

If you have WiFi connectivity issues, consult your router for any error signals and call your Internet Service Provider (ISP) for further help.

Reboot the Nest Thermostat

Reboot The Nest Thermostat

A reboot can seem like a nominal task to do in order to fix an issue like the Nest Thermostat not showing its live status on the Nest App.

But surprisingly, a simple reboot of the hardware and software works like a charm in a lot of troubleshooting cases, and hence can do the same for your Nest Thermostat too.

A reboot can refresh the system by removing any temporary issues that might be clogging the system.

These temporary bugs could have entered the system during a system update or even randomly during the daily operation of the Nest Thermostat.

Either way, these temporary files can be cleared away with a software refresh.

In order to perform a software reboot for your Nest Thermostat, simply follow these steps:

  • Click on the Nest Thermostat's ring to open the menu.
  • Select the settings option.
  • Tap on the Reset option from the resultant screen.
  • Select Restart to begin the process.

This safely performs a software restart on your Nest Thermostat.

Just as important as a software reboot is a reboot for the hardware of the Nest Thermostat.

This ensures that there are no stagnant charges left inside the internal components of the Nest Thermostat, which can at times result in a few hardware faults.

A hardware reboot (also called a power cycle) is done by completely depleting the charge inside the internal capacitors of the Nest Thermostat and then charging them up from scratch.

In order to perform a power cycle or hardware reboot on your Nest Thermostat, follow these steps:

  • Unplug the Nest Thermostat from the power socket.
  • Let it sit idle for a minute unplugged.
  • Long press the ring button on the Nest Thermostat for a few seconds to deplete the unit of all charges.
  • Plug the Nest Thermostat back into the power socket.
  • Let it sit idle for a minute powered on.

This safely reboots the hardware components inside the Nest Thermostat

Factory Reset the Nest Thermostat

Perform A Factory Reset On The Nest Thermostat

If the above steps fail in your case, then the only option you can do from the user end is to do a complete factory reset on your Nest Thermostat.

This will reset all settings on your Nest Thermostat as well as wipe out all user data on the device, clearing any bugs that might have clogged the system at some point.

Do note that this will also unlink all connected devices, so you might need to pair your Google or Nest account again with the application.

That being said, this still stands as the ultimate step you can do in order to fix your Nest Thermostat showing it is offline on the Nest app even though it is online.

In order to do a proper factory reset on your Nest Thermostat, follow these steps:

  • Click on the Nest Thermostat's ring to open the menu.
  • Select the settings option.
  • Tap on the Factory Restart option from the resultant screen.
  • Tap on Yes to confirm your selection and begin the factory reset process.

This will safely factory reset your Nest Thermostat to just like it was when you initially purchased the device.

Final Thoughts

Final Thoughts

Nest Thermostats are not new to minor bugs like this and have survived through far worse issues in the past.

The issue of the Nest App showing the Nest Thermostat as offline despite it being online is a relatively new issue that has popped up, and Nest will soon fix it from their end.

With Google looking over the company, it is safe to say that Nest is only getting better at providing an impeccable smart home experience.

I hope my troubleshooting guide on how to fix the issue of your Nest Thermostat showing offline on the Nest app despite being online has been a good read and helped you.

Have a good day!
