An apparatus comprising a baseplate configured to be coupled to a door configured to be positioned in an open door position, a closed door position, and a plurality of door positions in between the open position and closed position; a motor; a circuitry electrically coupled to the motor and configured to be in communication with a remote computing device; at least one proximity sensor electrically coupled to the circuitry and configured to determine the door position with respect to a door frame; a drive wheel coupled to the motor and the circuitry, the drive wheel comprising an external surface, the external surface of the drive wheel configured to rotatably contact a ground surface; and wherein the motor is configured to be remotely activated by the remote computing device to engage the drive wheel to rotatably contact the ground surface to reposition the door responsive to receipt of a signal.

A door closer device for driving a door to a predetermined closed position includes an adjustment mechanism and a door closer which is integrated with the door. The adjustment mechanism includes a base, an adjusting plate and at least one fixing element, wherein the adjusting plate is stacked with the base and coupled with the door closer. The adjusting plate and the base respectively include at least one adjusting bore, and the adjusting bores are corresponding with each other. One of the adjusting bores includes a first limiting end and a second limiting end, and a first moving path is defined between the first and second limiting ends. The fixing element is disposed in the adjusting bores and can move along the first moving path to fix the adjusting plate on the base.
