Change Nest Temperature Sensor settings

The Google Nest Temperature Sensor can help improve your comfort if it’s a few degrees cooler or warmer than you like in a specific room or area of your home. Your thermostat will use the sensor’s temperature to more accurately heat or cool that room.

This article applies to the following Google Nest thermostat models in the US and Canada:

Nest Thermostat E

Nest thermostat e cooling

Nest Learning Thermostat

Nest thermostat gen 3 cooling

How to tell which thermostat you have

Note: The Nest Temperature Sensor is only compatible with the Google Nest Thermostat E and Google Nest Learning Thermostat. Use the Nest app to connect your sensor to your thermostat and change its settings.

View or change basic settings

  1. Open the Nest app.
  2. Tap Settings Nest settings icon on the home screen.
  3. Scroll down and select the sensor you’d like to change.

You can choose from the following options in the settings menu for your temperature sensor:

  • Associated to: Check which thermostats your sensor is connected to. You can also quickly change which thermostat your sensor reports to.
  • Check connection: Test the connection between your sensor and your thermostat. This is useful if you’ve moved your sensor to a new location and you want to make sure it’s in range.
  • Placement: Choose the room name your sensor uses in the Nest app and add a custom label to help you identify it.
  • Technical info: Find some basic technical information about your sensor like its battery status or when it last connected.
  • Remove Nest Temperature Sensor: Choose to remove your sensor from your account. You can’t use it again until you add it back.

Connect and disconnect sensors

You can connect a sensor to more than one thermostat. However, we only recommend this if you have two thermostats: one that only controls heating, and one that only controls cooling.

You can also connect up to 6 temperature sensors to one thermostat. This lets your thermostat monitor temperatures in different rooms with different sensors. However, your thermostat can only use one temperature sensor at a time to control your system.

To disconnect a sensor from your thermostat or connect it to another thermostat in your home, follow these steps:

  1. Open the Nest app.
  2. Tap Settings Nest settings icon on the home screen.
  3. Select your thermostat.
  4. Choose Manage sensors.
  5. Tap Temperature sensors to get a list of all the temperature sensors in your home. A blue checkmark will appear next to sensors that are already connected to your thermostat.
  6. To attach any available sensors to your thermostat, tap the empty checkbox next to it.

Set or change a sensor's schedule

After you’ve finished setup with the app, you’ll need to set a schedule for your sensor so your thermostat knows when to use it.

  1. Open the Nest app.
  2. Tap Settings Nest settings icon on the home screen.
  3. Tap your thermostat.
  4. Select Manage sensors.
  5. Choose Sensor schedule. If you’d like to set a schedule for your sensors, tap the button to turn this option on.
  6. You can then choose a temperature sensor (or your thermostat’s built-in sensors) to use for each block of time.

Morning: 7 am to 11 am

Midday: 11 am to 4 pm

Evening: 4 pm to 9 pm

Night: 9 pm to 7 am

Note: You can schedule the same sensor to be active at different times each day, but you cannot have more than one sensor per thermostat active at the same time.

Temperature schedule sensor

Check the temperature in rooms with sensors 

Follow the instructions below to check what the temperature is in all the rooms that have sensors in them.

Nest app temperature home screen

  1. Open the Nest app.
  2. Tap your thermostat on the home screen.
  3. At the bottom of the screen, a list of sensors connected to your thermostat will appear along with the current reported temperature. There will be a dot next to the temperature if that sensor is active.
Note: You might also get some additional sensor information comparing their room temperature to the temperature of the room where your thermostat is.

Manually change the active temperature sensor

You can manually switch which temperature sensor is active with the app. This can help if you’re in a room that isn’t comfortable but has a temperature sensor that’s not currently active.

  1. Open the Nest app.
  2. Tap your thermostat on the home screen.
  3. Any temperature sensors you have connected to your thermostat will appear at the bottom of the screen. A dot will appear next to the currently active sensor.
  4. Tap another sensor to have your thermostat use it to control your system.
Note: When the next sensor is scheduled to be active, your thermostat and sensors will automatically switch out of manual mode and back to their set schedule.
