"""Manual verification CLI for the real iSolarCloud client (both auth modes).

USE_MOCK_ISOLARCLOUD=false and ISOLARCLOUD_AUTH_MODE ("v1" or "oauth2") must
be set in .env along with the matching credentials -- see SETUP.md.

Usage (v1):
  python scripts/verify_isolarcloud_cli.py login
  python scripts/verify_isolarcloud_cli.py plants
  python scripts/verify_isolarcloud_cli.py devices --ps-id 1234567
  python scripts/verify_isolarcloud_cli.py history --hours 6

Usage (oauth2):
  python scripts/verify_isolarcloud_cli.py authorize-url
  # open the printed URL yourself, approve access, then copy the `code`
  # param from the (broken, expected) redirect URL:
  python scripts/verify_isolarcloud_cli.py exchange --code THE_CODE
  python scripts/verify_isolarcloud_cli.py plants
  python scripts/verify_isolarcloud_cli.py history --hours 6
