A home network system with a standby power saving function and a method for saving standby power thereof, wherein various home appliances exchange information with a home server from time to time. At least one home appliance for a home network is provided in the home network system to exchange information with the home server over a network line. The home appliance includes a controller for analyzing data received over the network line and generating and outputting a home appliance control signal in accordance with the analyzed result, a load for operating/stopping the home appliance in response to the home appliance control signal from the controller, a low voltage transformer (LVT) for receiving an external voltage and supplying a drive voltage to the controller to operate the load and controller, and an LVT relay and a power supply unit for cooperating to selectively supply the drive voltage and a standby voltage to the controller according to whether the home appliance is in operation. When the home appliance is in a standby mode, the supply of external power is interrupted and only the minimum power necessary for the controller is supplied, thereby making it possible to save the same amount of standby power as that of LVT leakage power.
