# Nest Binding

The Nest binding integrates devices by [Nest](https://store.google.com/us/category/connected_home?) using the [Smart Device Management](https://developers.google.com/nest/device-access/api) (SDM) API and the Works with Nest (WWN) API.

To be able to use the SDM API it is required to first [register](https://developers.google.com/nest/device-access/registration) and pay a US$5 non-refundable registration fee.

It is also possible to use the older WWN API with this binding.
For this you need to have the account details of a previously registered WWN API account.
Another requirement is that you have not yet migrated your Nest account to a Google account (which is irreversible).
It is no longer possible to register new WWN API accounts because the WWN API runs in maintenance mode.
See also [What's happening at Nest?](https://nest.com/whats-happening/).

Because the SDM and WWN APIs run on servers in the cloud, a connection with the Internet is required for sending and receiving information.
The binding uses HTTPS to connect to the APIs using port 443.
When using the WWN API, the binding also connects to servers on port 9553.
So make sure outbound connections to these ports are not blocked by a firewall.

## Supported Things

The table below lists the Nest binding thing types:

| Things                                  | Description                                                                                                                                    | SDM Thing Type | WWN Thing Type     |

The SDM API currently does not support Nest Protect devices.
There are no structure Things when using the SDM API, because the SDM API does not support setting the Home/Away status like the WWN API does.

To use one of the Nest APIs, add the corresponding Account Thing using the UI and configure the required parameters.
After configuring an Account Thing, you can use it to discover the connected devices which are then added the Inbox.

## SDM Account Configuration

### Google Account Requirement

To be able to use the SDM API it is required that you use a Google Account with your Nest devices.
If you still use the WWN API, you can no longer use the WWN API after migrating to a Google Account.
So if you have not yet migrated your account, check that all the functionality you require is provided by the SDM API and SDM Things in the binding.
Most notably, there is no support for the Nest Protect in the SDM API and you cannot change your Home/Away status.
To migrate to a Google account, follow the migration steps in the [Nest accounts FAQ](https://support.google.com/googlenest/answer/9297676?co=GENIE.Platform%3DiOS&hl=en&oco=0#accountmigration&accountmigration1&#accountmigration2&#accountmigration3&zippy=%2Chow-do-i-migrate-my-account)

### SDM Configuration Parameters

These parameters configure which SDM project is accessed using the SDM API and configure the OAuth 2.0 client details used for accessing the project.

First a SDM project needs to be created and configured:

1. Register for device access by clicking the "Go to Device Access Console" button and follow the instructions on the [Device Access Registration](https://developers.google.com/nest/device-access/registration) page.
1. Create a new SDM project on the [Projects](https://console.nest.google.com/device-access/project-list) page
    1. Give your project a name so it is easily recognizable
    1. "Skip" entering the OAuth client ID for now
    1. If you want to download camera images using the binding, it is required to "Enable" events.
       Enabling events also allows for faster thermostat state updates.
       The binding only uses events when the Pub/Sub configuration parameters of the Nest SDM Account Thing are also configured.
    1. After clicking the "Create project" button, the SDM project details of the created project show
1. Copy and save the **Project ID** at the top of the page (e.g. `585de72e-968c-435c-b16a-31d1d3f76833`) somewhere

Now an OAuth 2.0 client is created and configured for using the SDM API by the binding:

1. Configure the "Publishing status" of your Google Cloud Platform to "Production" ([APIs & Services > OAuth consent screen](https://console.cloud.google.com/apis/credentials/consent)) so the OAuth 2.0 tokens do not expire after 2 weeks
1. Create a new client on the "Credentials" page ([APIs & Services > Credentials](https://console.cloud.google.com/apis/credentials)):
    1. Click the "Create Credentials" button at the top of the page
    1. Choose "OAuth client ID"
    1. As "Application type" choose "TVs and Limited Input devices"
    1. Give it a name so you can remember what it is used for (e.g. `Nest Binding SDM`)
    1. Click "Create" to create the client
    1. Copy and save the generated **Client ID** (e.g. `1046297811237-3f5sj4ccfubit0fum027ral82jgffsd1.apps.googleusercontent.com`) and **Client Secret** (e.g. `726kcU-d1W4RXxEJA79oZ0oG`) somewhere
1. Configure the SDM project to use the created client:
    1. Go the the SDM [Projects](https://console.nest.google.com/device-access/project-list) page
    1. Click on your SDM Project to show its details
    1. Scroll to "Project Info > OAuth client ID" and open the options menu (3 stacked dots) at the end of the line
    1. Select the "Edit" option
    1. Copy/paste the saved OAuth 2.0 Client ID here (e.g. `1046297811237-3f5sj4ccfubit0fum027ral82jgffsd1.apps.googleusercontent.com`)
    1. Click the "Save" button at the end of the line to update the project

Finally, an SDM Account Thing can be created to access the SDM project using the SDM API with the created client:

1. Create a new "Nest SDM Account" Thing in openHAB
1. Copy/paste the saved SDM **Project ID** to SDM group parameter in the SDM Account Thing configuration parameters (e.g. `585de72e-968c-435c-b16a-31d1d3f76833`)
1. Copy/paste the saved OAuth 2.0 **Client ID** to SDM group parameter (e.g. `1046297811237-3f5sj4ccfubit0fum027ral82jgffsd1.apps.googleusercontent.com`)
1. Copy/paste the saved OAuth 2.0 **Client Secret** to SDM group parameter (e.g. `726kcU-d1W4RXxEJA79oZ0oG`)
1. Create an authorization code for the binding:
    1. Replace the **Project ID** and **Client ID** in the URL below with your SDM Project ID and SDM OAuth 2.0 Client ID and open the URL in a new browser tab:
       
       `https://nestservices.google.com/partnerconnections/{{ProjectID}}/auth?redirect_uri=urn:ietf:wg:oauth:2.0:oob&access_type=offline&prompt=consent&client_id={{ClientID}}&response_type=code&scope=https://www.googleapis.com/auth/sdm.service`
       
       For the example values used so far this is:
       
       `https://nestservices.google.com/partnerconnections/585de72e-968c-435c-b16a-31d1d3f76833/auth?redirect_uri=urn:ietf:wg:oauth:2.0:oob&access_type=offline&prompt=consent&client_id=1046297811237-3f5sj4ccfubit0fum027ral82jgffsd1.apps.googleusercontent.com&response_type=code&scope=https://www.googleapis.com/auth/sdm.service`
    1. Enable all the permissions you want to use with the binding and click "Next" to continue
    1. Login using your Google account when prompted
    1. On the "Google hasn't verified this app" page, click on "Advanced"
    1. Then click on "Go to ... (advanced)"
    1. Now "Allow" the SDM permissions and confirm your choices again by clicking "Allow"
    1. Next the "Sign in" page will show the **Authorization Code**
    1. Copy/paste the **Authorization Code** to the SDM group parameter in the openHAB Nest SDM Account Thing configuration
1. All required SDM Account Thing configuration parameters have now been entered so create it by clicking "Create Thing".

The SDM Account Thing should now be ONLINE and have as status description "Using periodic refresh".
It should also be possible to use the configured account to discover your Nest devices via the Inbox.

You can monitor the SDM API using the Google Cloud Platform Console via [API & Services > Smart Device Management API](https://console.cloud.google.com/apis/api/smartdevicemanagement.googleapis.com/overview).

If you've made it this far, it should be easy to edit the SDM Account Thing again and update it so it can also use SDM Pub/Sub events. :-)

### Pub/Sub Configuration Parameters

After configuring the SDM configuration parameters, a SDM Account Thing can be updated so it can listen to SDM events using Pub/Sub.
This is required if you want to download camera images using the binding or to get faster thermostat state updates.

Enable Pub/Sub events in your SDM project:

1. Open your SDM project details using the [Projects](https://console.nest.google.com/device-access/project-list) page
1. Scroll to "Project Info > Pub/Sub topic" and check if it is set to "Enabled"
1. If it is set to "Disabled", enable events:
    1. Open the options menu (3 stacked dots) at the end of the line
    1. Select the "Edit" option
    1. Check the "Enable events" option
    1. Click the "Save" button at the end of the line to update the project

Lookup your Google Cloud Platform (GCP) Project ID:

1. Open the [IAM & Admin > Settings](https://console.cloud.google.com/iam-admin/settings)
1. Copy and save the GCP **Project ID** (e.g. `openhab-12345`)

Next an OAuth 2.0 client is created which is used to create a Pub/Sub subscription for listening to SDM events by the binding:

1. Open the "Credentials" page ([APIs & Services > Credentials](https://console.cloud.google.com/apis/credentials)):
1. Click the "Create Credentials" button at the top of the page
1. Choose "OAuth client ID"
1. As "Application type" choose "TVs and Limited Input devices"
1. Give it a name so you can remember what it is used for (e.g. `Nest Binding Pub/Sub`)
1. Click "Create" to create the client
1. Copy and save the generated **Client ID** (e.g. `1046297811237-lg27h26kln6r1nbg54jpg6nfjg6h4b3n.apps.googleusercontent.com`) and **Client Secret** (e.g. `1-k78-XcHhp_gdZF-I6JaIHp`) somewhere

Finally, the existing SDM Account Thing can be updated so it can subscribe to SDM events:

1. Open the configuration details of your existing "Nest SDM Account" Thing in openHAB
1. Copy/paste the saved GCP **Project ID** to Pub/Sub group parameter (e.g. `openhab-123`)
1. Enter a name in **Subscription ID** that uniquely identifies the Pub/Sub subscription used by the binding
   
   > Must be 3-255 characters, start with a letter, and contain only the following characters: letters, numbers, dashes (-), periods (.), underscores (_), tildes (~), percents (%) or plus signs (+). Cannot start with  goog.
1. Copy/paste the saved OAuth 2.0 **Client ID** to Pub/Sub group parameter (e.g. `1046297811237-lg27h26kln6r1nbg54jpg6nfjg6h4b3n.apps.googleusercontent.com`)
1. Copy/paste the saved OAuth 2.0 **Client Secret** to Pub/Sub group parameter (e.g. `1-k78-XcHhp_gdZF-I6JaIHp`)
1. Create an authorization code for the binding:
    1. Replace the **Client ID** in the URL below with your Pub/Sub OAuth 2.0 Client ID and open the URL in a new browser tab:
       
       `https://accounts.google.com/o/oauth2/auth?client_id={{ClientID}}&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&scope=https://www.googleapis.com/auth/pubsub`
       
       For the example client this is:
       
       `https://accounts.google.com/o/oauth2/auth?client_id=1046297811237-lg27h26kln6r1nbg54jpg6nfjg6h4b3n.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&scope=https://www.googleapis.com/auth/pubsub`
    1. Login using your Google account when prompted
    1. On the "Google hasn't verified this app" page, click on "Advanced"
    1. Then click on "Go to ... (advanced)"
    1. Now "Allow" the Pub/Sub permissions and confirm your choices again by clicking "Allow"
    1. Next the "Sign in" page will show the **Authorization Code**
    1. Copy/paste the **Authorization Code** to the Pub/Sub group parameter in the openHAB Nest SDM Account Thing configuration
1. All required Pub/Sub Account Thing configuration parameters have now been entered so click "Save" to update the SDM Account Thing configuration.

The SDM Account Thing should now be ONLINE and have as status description "Using periodic refresh and Pub/Sub".

The created subscription can also be monitored using the Google Cloud Platform Console via [Pub/Sub > Subscriptions](https://console.cloud.google.com/cloudpubsub/subscription/list).

## SDM Device Configuration

| Configuration Parameter | Required | Default | Description                                                               |
|-------------------------|----------|---------|---------------------------------------------------------------------------|
| deviceId                | X        |         | Identifies the device in the SDM API                                      |
| refreshInterval         |          | 300     | This is refresh interval in seconds to update the Nest device information |

Decreasing the `refreshInterval` may cause issues when you have a lot of devices connected because it may cause API rate limits to be exceeded.
You may want to decrease the `refreshInterval` for a Thermostat if Pub/Sub events have not been configured to provide state updating.

## WWN Account Configuration

To configure the binding to use the WWN API, add a new "Nest WWN Account" Thing in the UI and enter the **Product ID**, **Product Secret** and **Access Token** of an existing WWN account as configuration parameters.
It is no longer possible to register new WWN accounts with Nest because the WWN API runs in maintenance mode.

## Discovery

The binding will discover all Nest Things from your account when you add and configure a Nest SDM or WWN Account Thing.

## Channels

### SDM/WWN Account Channels

The account Thing Types do not have any channels.

### SDM Camera/Display/Doorbell Channels

The state of these channels is based on Pub/Sub events sent by the SDM API.
So make sure the Pub/Sub account details are properly configured in the `sdm_account`.

| Channel Type ID                  | Item Type | Description                                         | Read Write |

| sound_event#image                | Image     | Static image based on a sound event                 |      R     |
| sound_event#timestamp            | DateTime  | The last time that a sound was detected             |      R     |

The `chime_event` group channels only exist for doorbell Things.
Each image channel has the `imageWidth` and `imageHeight` configuration parameters that can be used for configuring the image size in pixels.
The maximum camera resolution is listed as `maxImageResolution` property in the Thing properties.

### SDM Thermostat Channels

| Channel Type ID     | Item Type            | Description                                                            | Read Write |

Note that the Nest API rounds Thermostat values so they will differ from what shows up in the Nest App.
The Nest API applies the following rounding:

*   degrees Celsius to 0.5 degrees
*   degrees Fahrenheit to whole degrees
*   humidity to 5%

## Example

You can use the discovery functionality of the binding to obtain the deviceId and structureId values for defining Nest things in files.
