Integrating services like Google Calendar, Spotify, and Xbox has historically posed a challenge for newcomers to Home Assistant. These services, though widely used, require a more intricate setup process. However, with the upcoming release of Home Assistant Core 2022.6, this will change. The new update will simplify the process by managing OAuth2 application credentials directly from the UI and automatically setting up redirect URLs. This article delves into the specifics of these changes and highlights why they are a significant improvement for Home Assistant users.

Understanding OAuth2
OAuth2 (Open Authorization 2.0) is an open standard for access delegation, commonly used as a way to grant websites or applications limited access to a user's information without exposing their passwords. It works by allowing users to authorize third-party services to access their resources on another service. For example, it lets you log in to a third-party application using your Google or Facebook account, thereby granting the application permission to use your account data without revealing your login credentials.
The OAuth2 framework involves four main roles: the resource owner (user), the client (application requesting access), the resource server (where the resource is located), and the authorization server (which issues the access token). The process typically begins with the client requesting authorization from the resource owner. If the owner consents, the authorization server issues an access token to the client. This token is then used to authenticate and gain access to the resource server, ensuring secure and controlled access to user data.
Growing List of YAML-Free Home Assistant Integrations
For those who prefer to avoid text editors, there's good news: Home Assistant continues to move towards a YAML-free future. The configuration.yaml file will remain untouched when integrating the following services with Home Assistant Core 2022.6:
- Google Calendar
- Spotify
- Home Connect
- Honeywell Lyric
- Neato Botvac
- Netatmo
- Withings
- Xbox
Some of these services already supported YAML-free integration before this release. The upcoming changes mean that YAML configuration for these services will be deprecated in future Home Assistant releases.
Updating Home Assistant Core: What You Need to Know
If you are updating Home Assistant Core, you won't need to make any manual changes. Existing OAuth2 application credentials in the YAML configuration file will automatically be imported upon updating. This thoughtful approach by the developers ensures a smooth transition, as YAML configuration will eventually be phased out in future releases.
Easier Integration of Google Calendar with Home Assistant
While the new changes do not eliminate the need for a Client ID and Client Secret, they do simplify the process. You still need to acquire these from the Google Developers Console. However, instead of adding this information to the configuration.yaml file, you can now enter it directly into the appropriate fields in the Home Assistant dashboard during the integration setup. This means you no longer need to add the following lines to your YAML configuration:
google:
client_id: YOUR_CLIENT_ID
client_secret: YOUR_CLIENT_SECRETThis change spares you from editing configuration files and reduces the risk of accidentally sharing sensitive information like your Client ID and Client Secret. Overall, this update enhances both the ease and security of integrating popular services with Home Assistant.
Additional Changes to Google Calendar Integration
The changes to the Google Calendar integration go beyond just authentication. The integration now behaves like other integrations set up through the Dashboard, rather than the YAML configuration. Home Assistant will now list your individual calendars as entities, allowing you to set permissions (read and write or read-only) directly from the integrations page by clicking the configure button.
These changes also allow for easy customization of your calendars. From the entities page, you can enable, disable, or hide calendars. You can also use the graphical interface to change a calendar's name, entity ID (e.g., calendar.something), icon, and area.
Previously, the configuration for Google Calendar looked something like this:
- cal_id: "*****@group.calendar.google.com"
entities:
- device_id: test_everything
name: Give me everything
track: true
Conclusion
The upcoming release of Home Assistant Core 2022.6 brings significant improvements in integrating popular services by managing OAuth2 application credentials directly from the UI and setting up redirect URLs automatically. These changes make the integration process easier and more secure. Existing users will benefit from the automatic import of their credentials, while the new setup flow reduces the risk of exposing sensitive information.
By continuing to move towards a YAML-free future, Home Assistant enhances user experience, making it more accessible for beginners while maintaining the technical rigour required by more advanced users. These updates mark a significant step forward in Home Assistant's mission to simplify and streamline the integration of various services into a cohesive smart home environment.
