Why Does My Nest Thermostat Keep Changing Temperature? [EXPLAINED]

How comfortable you are in your home is directly related to the temperature of your thermostat.

To keep yourself comfortable all day and all night, you program your smart thermostat.

In any case, you believe that you have done so. But upon entering your house following a long day at work, you find that the temperature has risen from 72 degrees to 68 degrees. What has happened?

It is important to remember that smart thermostats require some learning to operate, and this can leave you feeling less than smart. This is a common occurrence, but they are often not as evident as it should be.

Occasionally, it seems as if you have no control over your device and it just does its own thing.

However, there is a way to overcome this problem as well, and it has to do with the way the device is programmed to collect and use the information to adjust the temperature setting so that it is as comfortable as possible.

It is one function of the Google Nest that is particularly susceptible to causing these issues, a problem that has been confusing buyers for many years.

Unfortunately, you will have to perform some troubleshooting for this issue.

Making changes to Nest Learning, which essentially automates scheduling for you, is required.

The problem with this method is that, as you now know all too well, it doesn’t always work as well as it should.

Is it normal for Nest thermostats to change the temperature so frequently? I will explain.

With the Nest Learning auto-scheduling feature integrated into the Google Nest thermostat, you can adjust the temperature of your home. You can set the high and low-temperature parameters for the thermostat to automatically adjust based on your preferences.

You will be required to complete this process during the setup process, but you can make adjustments to the system afterward.

How does auto-scheduling affect the temperature setting of the Google Nest thermostat?

Is it possible to change the settings for auto-scheduling?

What is the procedure for disabling the Nest learning feature?

If the temperature sensor malfunctions, what should you do?

We will explain why the Nest thermostat continually experiences temperature changes and how you can resolve the problem.

What is the cause of the Nest Thermostat’s constantly changing temperature?

A few reasons have led to changes in the Google Nest Thermostat.

The most common reason is that auto-scheduling is enabling, but other features can cause this problem. The following are also possible culprits: Home/Away, Early-On, and Eco Mode.

Let’s examine why each of these could be problematic.


A schedule that is automatically generated is set up when the program is initially installed. Users are asked to select temperature preferences for high and low temperatures.

Based on the data gathered from the activities you are engaged in each day, the system sets the temperature.

As a result, it can learn your likes and preferences and adjust its settings based on the data it gathers.

As a consequence, it creates a schedule for your home’s heating and air conditioning.

This feature allows you to switch between home and away

When you are away from home, the thermostat utilizes the Home/Away setting.

Once it detects that you have left and returned, the thermostat adjusts the temperature accordingly.

Ecology Mode

When your system senses that no one is at home, it will switch to Eco Mode.

Your smartphone’s GPS location is used to accomplish this.

The Eco Mode can be turned on manually by the user, but when this is done, the Nest Thermostat is essentially inoperative until the temperature in your residence falls below or rises above its set temperature.

The thermostat will automatically switch on to provide your home with a comfortable temperature once this occurs.

The temperature range can be modified by simply changing the settings on your thermostat or the Nest app if the default Eco Mode settings are not suitable for you.

Featured in Early Access

With Early-On, your air conditioning or heating will begin working before the scheduled time, thus getting your home to the desired temperature earlier than scheduled.

To adhere to a set schedule, this feature can be disabled.

What can be done to prevent Nest Thermostat from changing temperature?

It is possible to disable Auto-Schedule using your smartphone and the Nest app.

Locate the name of your thermostat in the Google Nest app.

Turn off Auto-Schedule by going into its settings.

Consequently, the system will follow the schedule that you have established, rather than the one the system tries to impose upon you.

If you ever want to turn it back on, you will still find Google Nest’s schedule there.

However, disabling this feature will merely prevent the system from learning more about you.

The thermostat will remain at the temperature you selected until you manually adjust it, just like your traditional thermostat, until you create a schedule after you delete the one it set for you.

What is the procedure for turning off Auto-Schedule?

The following steps will enable you to disable Auto-Schedule:

  1. From your smartphone or tablet, launch the Google Nest application.
  2. Click on the name of your Nest Thermostat.
  3. Select the Settings option.
  4. The Auto-Schedule slider can be toggled off by clicking it.

Also, remember that you can turn off Auto-Schedule from your thermostat. 

  1. Select the Settings option.
  2. Click on Nest Sense.
  3. Select Auto-Scheduling.
  4. Turn it off.

What is the procedure for clearing the schedule?

In addition to deleting or modifying the schedule, you can also create a new one. All three of these options are straightforward.

The schedule should be deleted as follows:

  1. Click on the Settings option on your thermostat.
  2. Select the Reset button.
  3. Select Schedule.
  4. Then select either “Clear” or “Reset”.

The following steps should be followed to create a new schedule:

  1. Launch the Nest application.
  2. Click on the thermostat of your choice.
  3. Then click on Schedule.
  4. Adjust the temperature as necessary.

The schedule will be adjusted as follows: 

  1. Launch the Nest application.
  2. Select the appropriate thermostat.
  3. Choose the schedule.
  4. Change the temperature setpoints accordingly.

Sensors for Nest Thermostats

You can place the Google Nest Thermostat Sensor anywhere in your home so you can control the temperature.

Using this device, you can control the temperature in a particular room with your thermostat.

Due to this device being located in a different room, it may explain temperature differences between rooms.

In addition, if the sensor ever becomes defective, this could explain the difference in temperature in that one room that wouldn’t exist otherwise.

Concluding Remarks

Nest Learning Thermostats are smart thermostats from Google.

You can adjust your home’s HVAC system according to your habits and preferences as the system learns about them.

Is the system always accurate? This is not always the case, but it usually approaches the mark.

It is possible to maintain a more consistent temperature by disabling the automatic temperature change features, although this may also defeat the purpose of the Nest Thermostat.

Make some adjustments to the settings to see if they help.
