Issue Summary
The Opower integration in Home Assistant was failing with a KeyError: 'redirectUrl' error when attempting to authenticate with SMUD (Sacramento Municipal Utility District).
Investigation Steps

Initial Error Analysis:
The original error occurred because the Opower integration was expecting a 'redirectUrl' parameter in the authentication response, but this parameter was missing.

Authentication Flow Analysis:
I created an external Python script to test the SMUD authentication flow directly, which revealed:

  • SMUD's authentication system has significantly changed
  • The login process now involves different redirection patterns
  • The expected 'redirectUrl' parameter is no longer present in responses
  • The Okta-based SSO that the integration was designed for appears to be gone or changed

Authentication Testing:
I attempted to follow the new authentication flow but were unable to successfully authenticate, possibly due to:

  • Changes in how SMUD handles account selection
  • Additional security measures in the authentication process
  • Potential multi-factor authentication requirements

Conclusions
The Opower integration for SMUD is failing because SMUD has fundamentally changed their authentication system, removing or altering the Okta-based SSO flow that the integration was designed to use. The missing 'redirectUrl' parameter indicates that the underlying API or authentication mechanism has changed substantially.

Versioning:
Opower: 0.9
HA:

  • Core 2025.3.3
  • Frontend 20250306.0
