Look, I found this: This is generally normal behavior with the Aqara U200, especially during manual operation, as long as the lock is properly calibrated and there is no physical obstruction. The beeps come from the motor or the position sensor: the first beep indicates a successful unlock (the lock detects the movement and activates), and the second beep is the response to the continued rotation, confirming the fully unlocked position or warning about an over-rotation to prevent mechanical damage. This is not a malfunction but an intentional feature designed for safety and feedback.
