/auth/external/callback`).

- Go back to the [API Console](https://console.developers.google.com/apis/credentials) and select your *OAuth 2.0 Client ID*.
- Add the URL to the list of *Authorized redirect URIs* and click **Save** and start the flow over.

{% enddetails %}
- When configuring the OAuth Client ID redirect URI, you may see an error such as *must end with a public top-level
domain (such as .com or .org)* or *must use a valid domain that is a valid top private domain*. This means that you
may need to change the URL you use to access Home Assistant in order to access your devices.
{% details "Details about URL configuration" %}
- See [Securing](https://www.home-assistant.io/docs/configuration/securing/) Home Assistant for convenient solutions e.g. [Nabu Casa](https://www.nabucasa.com/) or Duck DNS.
- There are subtle [rules](https://developers.google.com/identity/protocols/oauth2/web-server#uri-validation) for what types of URLs are allowed, namely that they must use SSL and a publicly known hostname, though your Home Assistant ports do not need to be exposed to the internet.
- You can use any publicly known hostname you own
- As a hack, you can use hosts tricks to temporarily assign a public hostname to your Home Assistant IP address.
{% enddetails %}
- *Error 403: access_denied* means that you need to visit the [OAuth Consent Screen](https://console.developers.google.com/apis/credentials/consent) and add your Google Account as a *Test User*.
- *Error: invalid_client no application name* means the [OAuth Consent Screen](https://console.developers.google.com/apis/credentials/consent) has not been fully configured for the project. Enter the required fields (App Name, Support Email, Developer Email) and leave everything else as default.
- *Subscriber error: Subscription misconfigured. Expected subscriber_id to match...* means that the `configuration.yaml` has an incorrect `subscriber_id` field. Re-enter the *Subscription Name* which looks like `projects/project-label-22ee1/subscriptions/SUBSCRIBER_ID`. Make sure this is not the *Topic name*.
- *Subscriber error: Subscription misconfigured. Expected topic name to match ...* means that the topic name in the Google Cloud Console was entered incorrectly. The topic name comes from the Device Console and must start with `projects/sdm-prod/topics/`. It is easy to make the mistake of creating a new topic rather than manually entering the right topic name.
- *Not receiving updates* typically means a problem with the subscriber configuration. Changes for things like sensors or thermostat temperature set points should be instantly published to a topic and received by the Home Assistant subscriber when everything is configured correctly.
- You can see stats about your subscriber in the [Cloud Console](https://console.cloud.google.com/cloudpubsub/subscription/list) which includes counts of messages published by your devices, and how many have been acknowledged by your Home Assistant subscriber. You can also `View Messages` to see examples of published. Many old unacknowledged messages indicate the subscriber is not receiving the messages and working properly or not connected at all. Double check the `subscriber_id` matches the `Subscription Name`
- To aid in diagnosing subscriber problems or camera stream issues it may help to turn up verbose logging by adding some or all of these to your `configuration.yaml` depending on where you are having trouble:
```yaml
logger:
default: info
logs:
homeassistant.components.nest: debug
homeassistant.components.nest.climate_sdm: debug
homeassistant.components.nest.camera_sdm: debug

```
## Camera
All Google Nest Cam models, Google Nest Hello Video Doorbell, Google Nest Hub Max expose a [CameraLiveStream](https://developers.google.com/nest/device-access/traits/device/camera-live-stream) via the SDM API, which returns a RTSP live stream which can be viewed from Home Assistant.
Given a camera named `Front Yard` then the camera is created with a name such as `camera.front_yard`.
## Climate
All Google Nest Thermostat models are exposed as a `climate` entity that use the [Thermostat Traits](https://developers.google.com/nest/device-access/traits/device/thermostat-hvac) in the SDM API. State changes to the thermostat are reported to Home Assistant through the Cloud Pubsub subscriber.
Given a thermostat named `Upstairs` then the climate entity is created with a name such as `climate.upstairs`
## Sensor
All Google Nest Thermostat models have traits exposed from the SDM API. The initial values of the sensors are fetched on startup, then updated regularly using the Cloud Pubsub subscriber. The following traits are supported with sensors:
- [Temperature](https://developers.google.com/nest/device-access/traits/device/temperature)
- [Humidity](https://developers.google.com/nest/device-access/traits/device/humidity)
Given a thermostat named `Upstairs` then sensors are created with names such as `sensor.upstairs_temperature` or `sensor.upstairs_humidity`.
## Automation and Device Triggers
The Nest integration makes [device triggers](/docs/automation/trigger/#device-triggers) available to enable automation
in Home Assistant. You should review the [Automating Home Assistant](/getting-started/automation/) getting started guide on automations or the [Automation](/docs/automation/) documentation for full details.

All Google Nest Cam models and the Google Nest Hello Video Doorbell support device triggers:
- **Motion detected**
- **Person detected**
- **Sound detected**
- **Doorbell pressed** *for Doorbell only*
The lower level Pub/Sub subscriber receives events in real time and internally fires `nest_event` events within Home Assistant:
| Device Trigger | Pub/Sub Event | `nest_event` |
| -------------- | ----- | ------------- |
| Motion detected | [CameraMotion](https://developers.google.com/nest/device-access/traits/device/camera-motion#events) | `motion_detected` |
| Person detected | [CameraPerson](https://developers.google.com/nest/device-access/traits/device/camera-person#events) | `person_detected` |
| Sound detected | [CameraSound](https://developers.google.com/nest/device-access/traits/device/camera-sound#events) | `sound_detected` |
| Doorbell pressed | [DoorbellChime](https://developers.google.com/nest/device-access/traits/device/doorbell-chime#events) | `doorbell_chime` |
## Example
This automation will trigger when a `nest_event` event type with a type of `camera_motion` is received from the specified `device_id`.
```yaml
alias: "motion alert"
trigger:
- platform: event
event_type: nest_event
event_data:
device_id: YOUR_DEVICE_ID
type: camera_motion
action:
- service: notify.mobile_app_pixel_2
data:
title: motion detected
message: front door motion detected
data:
image: /api/camera_proxy/camera.front_door
```
The action in this section uses the [Android Companion App](https://companion.home-assistant.io/docs/notifications/notifications-basic/) and the camera proxy to send a notification with a snapshot from the camera.
# Legacy Works With Nest API
This section contains instructions for the Legacy [Works with Nest](https://developers.nest.com/) API.
New users are not currently able to set up a Works With Nest Developer account. The documentation is preserved here for existing users of the API.
{% details "Legacy Works with Nest Configuration Steps" %}
The Nest integration is the main integration to integrate all [Nest](https://nest.com/) related platforms. To connect Nest, you will have to [sign up for a developer account](https://developers.nest.com/products) and get a `client_id` and `client_secret`.
There is currently support for the following device types within Home Assistant:
- [Binary Sensor](#binary-sensor)
- [Camera](#camera)
- [Climate](#climate)
- [Sensor](#sensor)
**Setting up developer account**
1. Visit [Nest Developers](https://developers.nest.com/), 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](https://developers.nest.com/products)" at top of page.
5. Click "[Create New Product](https://developers.nest.com/products/new)"
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**
```yaml
# Example configuration.yaml entry
nest:
client_id: CLIENT_ID
client_secret: CLIENT_SECRET
```
```yaml
# Example configuration.yaml entry to show only devices at your vacation and primary homes

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.

| `structure` | yes | String, will default to all configured Nest structures if not specified.
Examples:
```yaml
# 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
```
```yaml
# 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:

```
**Troubleshooting**
- For trouble with the SDM API OAuth authorization flow with Google, see [Troubleshooting](https://developers.google.com/nest/device-access/authorize#troubleshooting) which includes guidance for errors like `redirect_uri_mismatch` where Google needs to know about your external URL.
- If you're getting [rickrolled](https://www.youtube.com/watch?v=dQw4w9WgXcQ) by the Legacy API 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](/integrations/nest/) configured to use the platforms below.
**Binary Sensor**
The `nest` binary sensor platform lets you monitor various states of your [Nest](https://nest.com) devices.
You must have the [Nest component](/integrations/nest/) 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](/integrations/nest/) configuration in your `configuration.yaml` file with the following settings:
```yaml
# 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](/integrations/nest/).
{% 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](https://nest.com/camera/meet-nest-cam/) camera in Home Assistant.
The Legacy API integration allows you to watch still frames from a video stream (not live stream). The Legacy API also supports the `camera.turn_on` and `camera.turn_off` services.
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](https://nest.com).
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](https://nest.com) 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](/integrations/nest/) configuration in your `configuration.yaml` file with the following settings:
```yaml
# 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](/integrations/nest/).
{% 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](#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 are liable 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](https://nest.com/alarm-system/overview/) 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](https://developers.nest.com/documentation/cloud/security-guide).
You may need to change your ["Product"](https://developers.nest.com/products) 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](#binary-sensor) while the structure is in `away` mode (see `away` in [binary_sensor.nest](#binary-sensor), 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`.
