An interface control circuit, a control method and an interface control device. The interface control circuit is suitable for use in a dimming system compatible with both DALI dimming and push-button dimming. The interface control circuit includes a DALI signal reception control module having a first switch element. The DALI signal reception control module is configured to be enabled, upon a voltage at a power supply terminal of the interface control circuit reaching a pre-start voltage, to turn on or off the first switch element according to the magnitude of a voltage on a DALI bus. The pre-start voltage is lower than a start voltage of the interface control circuit. This invention can ensure accuracy and reliability of rapid communication reestablishment over a period of time from a power-off to the next power-on of the DALI bus.
