• Secure Authentication: Full OAuth2 integration with Tesla's Fleet API including proper token management and refresh flows
• Rich Command Set: Over 30 vehicle commands organized into logical groups:
  • Basic controls (lock/unlock, honk, lights)
  • Climate control (temperature, seat heating/cooling)
  • Charging management
  • Media controls
  • Navigation
  • Windows/sunroof control
  • And much more!

🛡️ Security & Best Practices

• Follows Tesla's official Fleet API guidelines

This pull request introduces a new extension for controlling Tesla vehicles via the Fleet API and includes updates to the Single Sign-On (SSO) process for Tesla OAuth authentication. Additionally, environment variables for Tesla OAuth credentials have been added to the Docker configuration files.

Tesla Vehicle Control Extension:

• agixt/extensions/tesla.py: Added a new tesla class that provides various commands for controlling Tesla vehicles, including locking/unlocking doors, controlling climate settings, managing charging, and sending navigation commands. The extension requires OAuth authentication with Tesla.

Tesla OAuth SSO:

• agixt/sso/tesla.py: Implemented the TeslaSSO class to handle OAuth authentication with Tesla, including obtaining access and refresh tokens, and retrieving user information. Added functions for handling the OAuth flow and generating authorization URLs.

Docker Configuration:

• docker-compose-dev.yml: Added TESLA_CLIENT_ID and TESLA_CLIENT_SECRET environment variables to support Tesla OAuth authentication in the development environment.
• docker-compose.yml: Added TESLA_CLIENT_ID and TESLA_CLIENT_SECRET environment variables to support Tesla OAuth authentication in the production environment.
