Abstract

The present invention relates to a remote power control method and a device thereof, and in the related art, a home appliance without a remote control or a reservation function is inconvenient for a user to turn on / off a power switch of the home appliance directly. A device that can turn on / off power with a remote control by attaching a circuit is commercially available, but the user does not completely solve the problem that inconveniences the user because the user moves to the position where the control circuit is visible and turns on / off the power with the remote control. there was. In order to solve this problem, the present invention inquires and determines the power on / off state of each position, and then, in order to control to turn on / off power of an arbitrary position as necessary, transmits a command using a power line and is controlled by the command. It is configured to display the control status by transmitting the status to the remote control, the present invention can determine the power control status of each position at any position to control the power of the desired position to provide convenience to the user and also to reservation setting Since the power can be controlled at a desired time, the power consumption can be reduced and the method effect can be exerted in the absence of the user.
