How Does Nest Function When The Internet Go Out? Nest will function without a Wi-Fi connection. However, it cannot be used as a “Smart” thermostat and only as a regular thermostat. You can still control the HVAC systems using the thermostat interface.
Nest products work best with a reliable 24/7 internet connection, so you'd need to keep your mobile hotspot device at home all the time. If your Nest products don't have a continuous internet connection, you won't be able to view their status or receive certain notifications to your phone.
A failed internet connection will prevent you from remote access and controlling the advanced features of your smart thermostat. However, since cooling and heating is a basic function of your air conditioning system, it does not get affected.
Your thermostat will show a blank screen and the display will be unresponsive.
It can still record video and store it locally when the Wi-Fi or Internet goes out, and then upload it to the cloud when it reconnects. However, because it doesn't have a backup battery, it won't record and save video locally when the power goes out.
While smart thermostats can operate manually without an internet connection, many of their advanced features need Wi-Fi. If your internet connection is unstable or goes down frequently, you won't be able to take full advantage of your system.
The Google Nest Thermostat and Nest Learning Thermostat (4th gen) can only be set up in the Google Home app. The app guides you through compatibility checks, installation, and setup. It also helps you select the right options for you and your home.
While it can function as a basic thermostat without Wi-Fi, connecting it to the internet unlocks its full potential, allowing you to control and monitor your home's temperature remotely.
Wi-Fi thermostats take advantage of the times you aren't home to turn down the heat or turn up the air conditioning. You can also set the temperature remotely from your smart phone if you forget to change it when you leave the house.
If the Internet is down, it continues to operate normally, including changing temperatures at scheduled times, except that you can't make changes from the web/app.
Note: Nest Protects do not rely on Wi-Fi for wireless interconnect. However, if your Wi-Fi network goes down, you won't be able to get notifications, view status, or update settings in the app. Your Nest Protects can still detect smoke and carbon monoxide, communicate with one another, and sound an alert.
Nest will function without a Wi-Fi connection. However, it cannot be used as a “Smart” thermostat and only as a regular thermostat. You can still control the HVAC systems using the thermostat interface. It might still be able to implement the schedule and settings that have been set.
Going forward, you can use both the Home app and the Nest app with your Google Account to manage the devices in your home.
If you do not have Wi-Fi connection in your home, your smart thermostat will essentially act like a basic device that has been around for decades. The heating and cooling of your house can easily be handled without an internet connection. You will need to set and change the temperature directly on the thermostat.
If your Google Nest thermostat won't turn on and you see a blinking red or green light, or no light at all, there could be a power issue or your thermostat may have frozen during a software update.
Answer / Solution. Yes, your thermostat will keep working with the schedule it has stored in its memory. However you will not be able to remotely control your heating system until the internet connection is restored.
