The Nest integration is the main integration to integrate all Nest related platforms. To connect Nest, you will have to sign up for a developer account and get a client_id and client_secret.

There is currently support for the following device types within Home Assistant:

• Binary Sensor
• Camera
• Climate
• Sensor

Setting up developer account

New users are not currently able to set up a Works With Nest Developer account due to the change announced by Google. We will reach out to Nest to see if we can become a partner so that users joining Home Assistant after August can still use Nest. In the future we will add documentation on how to setup a Works With Google account and configure your Nest integration.

1. Visit Nest Developers, and sign in. Create an account if you don't have one already.
2. Fill in account details:

• The "Company Information" can be anything. We recommend using your name.

3. Submit changes
4. Click "Products" at top of page.
5. Click "Create New Product"
6. Fill in details:

• Product name must be unique. We recommend [email] - Home Assistant.
• The description, users, URLs can all be anything you want.
• Leave the "Redirect URI" Field blank

7. For permissions check every box and if it's an option select the read/write option. Note: there are important permissions under the "Other Permissions" category. If you are only adding a thermostat, do not just select the permissions under "Thermostat". You still need to check the boxes under "Other Permissions" in order to give you access to features like away mode, ETA, structure read/write, and postal code.

• The description requires a specific format to be accepted.
  • Use "[Home Assistant] [Edit] [For Home Automation]" as the description as it is not super important.

8. Click "Create Product"
9. Once the new product page opens the "Product ID" and "Product Secret" are located on the right side. These will be used as client_id and client_secret below.
10. Add the Nest integration to your configuration.yaml and restart Home Assistant. Then, go to Configuration > Integrations and select CONFIGURE next to Nest. Click the link in the configurator pop up to log into your Nest account and complete the OAuth. Copy the resulting PIN code into the pop up.

Connecting to the Nest Developer API requires outbound port 9553 on your firewall. The configuration will fail if this is not accessible.

Configuration

# Example configuration.yaml entry
nest:
  client_id: CLIENT_ID
  client_secret: CLIENT_SECRET

# Example configuration.yaml entry to show only devices at your vacation and primary homes
nest:
  client_id: CLIENT_ID
  client_secret: CLIENT_SECRET
  structure:
    - Vacation
    - Primary

{% configuration %} client_id: description: Your Nest developer client ID. required: true type: string client_secret: description: Your Nest developer client secret. required: true type: string structure: description: The structure or structures you would like to include devices from. If not specified, this will include all structures in your Nest account. required: false type: list {% endconfiguration %}

Service set_away_mode

You can use the service nest/set_away_mode to set the structure(s) to "Home" or "Away".

Service data attribute	Optional	Description
away_mode	no	String, must be away or home.
structure	yes	String, will default to all configured Nest structures if not specified.

Examples:

# Example script to set away, no structure specified so will execute for all
script:
  nest_set_away:
    sequence:
      - service: nest.set_away_mode
        data:
          away_mode: away

# Example script to set home, structure specified
script:
  nest_set_home:
    sequence:
      - service: nest.set_away_mode
        data:
          away_mode: home
          structure:
            - Apartment

Service set_eta

You can use the service nest/set_eta to set or update the estimated time of arrival window. Calling this service will automatically set the structure(s) to "Away". Structures must have an associated Nest thermostat in order to use ETA function.

Service data attribute	Optional	Description
eta	no	Time period, estimated time of arrival from now.
eta_window	yes	Time period, estimated time of arrival window. Default is 1 minute.
trip_id	yes	String, unique ID for the trip. Default is auto-generated using a timestamp. Using an existing trip_id will update that trip's ETA.
structure	yes	String, will default to all configured Nest structures if not specified.

Examples:

# Example script to set ETA, no structure specified so will execute for all
script:
  nest_set_eta:
    sequence:
      - service: nest.set_eta
        data:
          eta: 00:10:30
          trip_id: Leave Work

# Example script to update ETA and specify window, structure specified
script:
  nest_update_eta:
    sequence:
      - service: nest.set_eta
        data:
          eta: 00:11:00
          eta_window: 00:05
          trip_id: Leave Work
          structure:
            - Apartment

Service cancel_eta

You can use the service nest/cancel_eta to cancel an existing estimated time of arrival window. Structures must have an associated Nest thermostat in order to use ETA function.

Service data attribute	Optional	Description
trip_id	no	String, unique ID for the trip. Using an existing trip_id will update that trip's ETA.
structure	yes	String, will default to all configured Nest structures if not specified.

Examples:

# Example script to cancel ETA, no structure specified so will execute for all
script:
  nest_cancel_eta:
    sequence:
      - service: nest.cancel_eta
        data:
          trip_id: Leave Work

# Example script to cancel ETA, structure specified
script:
  nest_cancel_eta:
    sequence:
      - service: nest.cancel_eta
        data:
          trip_id: Leave Work
          structure:
            - Apartment

Troubleshooting

• If you're getting rickrolled instead of being able to see your Nest cameras, you may not have set up your developer account's permissions correctly. Go back through and make sure you've selected read/write under every category that it's an option.

Platforms

You must have the Nest component configured to use the platforms below.

Binary Sensor

The nest binary sensor platform lets you monitor various states of your Nest devices.

You must have the Nest component configured to use these sensors. The binary sensors will be setup if the nest integration is configured and the required configuration for the nest binary sensor is set.

Configuration

To enable binary sensors and customize which sensors are setup, you can extend the Nest component configuration in your configuration.yaml file with the following settings:

# Example configuration.yaml entry
nest:
  binary_sensors:
    monitored_conditions:
      - 'fan'
      - 'target'

By default all binary sensors for your available Nest devices will be monitored. Leave monitored_conditions blank to disable all binary sensors for the Nest component.

{% configuration %} monitored_conditions: description: States to monitor. required: false type: list {% endconfiguration %}

The following conditions are available by device:

• Nest Home:
  • away
• Nest Thermostat:
  • online
  • fan
  • is_using_emergency_heat
  • is_locked
  • has_leaf
• Nest Protect:
  • online
• Nest Camera:
  • online
  • motion_detected
  • person_detected
  • sound_detected

Camera

The nest platform allows you to watch still frames from a video stream (not live stream) of your Nest camera in Home Assistant.

The nest camera will automatically be setup when you do.

Nest Camera supports the camera.turn_on and camera.turn_off services since the 0.75 release.

Climate

The nest climate platform lets you control a thermostat from Nest.

Please note due to limitations with the European Nest Thermostat E, integration with Home Assistant for that thermostat is not possible.

Sensor

The nest sensor platform lets you monitor sensors connected to your Nest devices.

The sensors will be setup if the nest integration is configured and the required configuration for the nest sensor is set.

Configuration

To enable sensors and customize which sensors are setup, you can extend the Nest component configuration in your configuration.yaml file with the following settings:

# Example configuration.yaml entry
nest:
  sensors:
    monitored_conditions:
      - 'temperature'
      - 'target'

By default all sensors for your available Nest devices will be monitored. Leave monitored_conditions blank to disable all sensors for the Nest component.

{% configuration %} monitored_conditions: description: States to monitor. required: false type: list {% endconfiguration %}

The following conditions are available by device:

• Nest Home:
  • eta: Estimated time of arrival.
  • security_state: ok or deter. Security State. Only available when Nest Camera exists.
• Nest Thermostat:
  • humidity
  • preset_mode
  • temperature
  • target
  • hvac_state: The currently active state of the HVAC system, heat, cool or off (previously heating, cooling or off).
• Nest Protect:
  • co_status: Ok, Warning or Emergency
  • smoke_status: Ok, Warning or Emergency
  • battery_health: Ok or Replace
  • color_status: gray, green, yellow or red. Indicates device status by color in the Nest app UI. It is an aggregate condition for battery+smoke+CO states, and reflects the actual color indicators displayed in the Nest app.
• Nest Camera: none

Security State

This feature is not designed to transform your Home Assistant into a security system, neither Home Assistant nor Nest be liable to You for damages, or consequential damages of any character arising as a result of use this feature.

This feature does not depend on the Nest Secure alarm system and is not a reflection of the status of that system, nor does it react to state changes in that system.

This feature uses a new Nest Security API. You may need to change your "Product" permission setting to include Security State Read. After this permission change, you may need to re-authorize your client.

If a Nest Cam detects the presence of a person (see person_detected in binary_sensor.nest while the structure is in away mode (see away in binary_sensor.nest, the structure enters deter mode.

A deter state is re-evaluated after several minutes and relaxed to ok if no further person_detected events have occurred.

The security_state automatically switches to ok when the structure state is home.
