failed_disarm_motion

Error message

Blink failed to disarm camera motion detection.

What it means

HomeAssistantError with translation key 'failed_disarm_motion' raised when turning OFF the motion-detection switch times out: async_arm(False) raised TimeoutError. Mirror of the arm failure: the disarm command never got a timely response from Blink cloud.

Solutions

  1. Retry the disarm after a short wait
  2. Confirm the camera and sync module are online in the Blink app
  3. Check battery/quality of the camera link if one specific camera always fails
  4. Look for a Blink outage if all cameras are affected
Defensive patterns

Strategy: retry

Try / catch

try:
    await switch.async_turn_off()
except HomeAssistantError as err:
    if "failed_disarm_motion" in str(err):
        await asyncio.sleep(30)
        await switch.async_turn_off()

Prevention

When it happens

Trigger: Toggle the blink motion switch off while the camera is unreachable or Blink servers are slow; async_arm(False) exceeds its request timeout.

Common situations: Camera battery dead or offline; Blink cloud incident; leaving/disarming exactly when the coordinator refresh is running.
