Blink authorization failed

Error message

Blink authorization failed

What it means

ConfigEntryAuthFailed raised when turning ON the blink motion switch receives UnauthorizedError: the arm request was rejected because the Blink token is invalid. The handler calls async_start_reauth() then raises, flipping the entry into reauth state; the toggle operation is aborted.

Solutions

1. Complete the reauth flow in the UI, then re-run the automation/scene
2. Verify steady-state polling is working (no repeated 401s in logs) after reauth

try:
    await switch.async_turn_on()
except ConfigEntryAuthFailed:
    _LOGGER.warning("Blink reauth required before arm commands will work")

When it happens

Trigger: async_arm(True) gets a 401 from Blink because the stored auth token expired between the last successful refresh and this switch command.

Common situations: Switch automation fires hours after the token silently expired; Blink session rotation; account changes on the Blink side.
