daikin-controller-cloud

Library to generate/retrieve tokens to communicate with the Daikin cloud and to control Daikin devices via the cloud adapters like (BRP069C4x). The Library uses the new Daikin Europe Developer cloud API since v2.0.0.

Description

The newer Daikin devices sold since 2020 contain a newer Wifi Adapter (e.g. BRP069C4x) which only connects to the Daikin Cloud and is no longer reachable locally. These devices are only controllable through the Daikin Onecta API, which uses the OpenID Connect (OIDC) protocol for client authentication and authorization purposes.

This library facilitates interacting with the Onecta API by providing an abstraction over OIDC flows and token management.

Note: For devices with older WLAN-Adapters like BRP069A4x which can only be used by the Daikin Controller App please use the Daikin-Controller lib instead.

IMPORTANT information and best practices

The Onecta API limits each client application to 200 requests per day. Please make sure to not exceed this limit, as the API will block further requests for the day.

Because of this we propose the following usage limits to be implemented by the applications using this library:

• DO NOT generate more requests while being rate limited because else the unblock time increases! Use the retryAfter property of the RateLimitError to determine how long to wait for the next request.
• Better always read the full device details rather than single devices to make best use of the rate limit
• A default polling interval of 15 minutes should be sufficient for most use cases while leaving some space for controlling the devices too.
• Consider using a (longer) slow polling interval for timeframes where updated data are not that important - with this the normal polling interval could be faster.
• After you have "set" a value, wait at least 1-2 minutes before you read the updated values again because executing commands and updating the cloud data can take some time
• Ideally have at least 10 minutes time between switching the device power status because else thats bad for the moving parts of the devices

Pre-requisites

This library acts as an OIDC client towards the Onecta API and uses OIDC's Authorization grant to obtain the initial pair of OIDC tokens. As such, you'll have to provide the following:

1. The Client ID and Client Secret of a registered application tied to your Daiking Developer account. If you do not have such an account, yet, you can create one in the Daikin Developer Portal
2. The ability for the process that uses this library to listen on a local TCP port (configurable) in order to start an HTTP server that your browser will be redirected to at the end of the Authorization grant flow
3. A domain name or an IP that resolves to the machine that hosts the process using this library (if running locally you will not be able to use localhost or 127.0.0.1 as it is rejected by the Onecta API)

You will have to combine the port (point 2.) and domain name (point 3.) to create the URL to be set as the application's Redirect URI in the Daikin Developer portal. Note that the same URL must also be passed as a configuration parameter of the DaikinCloudController class or is build automatically from the provided values. Also note that the Redirect URI must use the secure https: protocol and that this library ships with its own self-signed SSL/TLS certificate, which will cause your browser to present you with a security warning.

Install

npm i daikin-controller-cloud

Code-Usage example

See src/example.ts.

DaikinControllerCloud options overview

Option	Required?	Description	Default
oidcClientId	Yes	The client ID of the registered Daikin Developer Account application
oidcClientSecret	Yes	The client secret of the registered Daikin Developer Account application
oidcCallbackServerExternalAddress	Maybe, see desc	The external address (domainname/IP) of the machine running the library, ot external Docker IP or such when using docker. Mandatory if oidcCallbackServerBaseUrl or customOidcCodeReceiver is not provided.
oidcCallbackServerBaseUrl	Maybe, see desc	The full externally reachable callback URl including protocol, domain/ip/basepath. If not provided will be build internally using oidcCallbackServerExternalAddressor oidcCallbackServerBindAddr and oidcCallbackServerPort
oidcCallbackServerPort	Maybe, see desc	The port the callback server listens on, required when customOidcCodeReceiver is not used.
oidcCallbackServerBindAddr	No	The address the callback server listens on, required when customOidcCodeReceiver is not used.	`
oidcAuthorizationTimeoutS	Yes	The timeout in seconds for the OIDC authorization flow
oidcTokenSetFilePath	No	The path to a file where the token set is stored. When not set the tokens are not persisted and application need to listen to "token_updated" event and store and restore itself!
certificatePathCert	No	The path to the SSL certificate	./cert/cert.key in library root
certificatePathKey	No	The path to the SSL key	./cert/cert.pem in library root
onectaOidcAuthThankYouHtml	No	The HTML content to be displayed after successful OIDC authorization, requiored when customOidcCodeReceiver is not used
customOidcCodeReceiver	No	A custom function to receive the OIDC code. WHen this is used the library donot start any Webservcer and application needs to handle this.
tokenSet	No	A token set to be used initially when no token file is stored
