<p>A home network system and a method of providing operation history data for the same are disclosed. The home network system includes at least one slave device and a master device, which includes a microprocessor, a memory, and a display unit. The microprocessor repeatedly sends a status request signal to the slave device and receives one or more response signal from the slave device in response to the request signal. The microprocessor constructs an operation history database in the memory by cumulatively storing operation status data included in each response signal. Finally, the microprocessor extracts data from the database when requested by a user, and the display unit displays the extracted data.
