The present invention relates to a home automation system and method using a portable terminal equipped with a remote control function for remotely controlling a specific home appliance by downloading a control signal code value from an automatic automation center or a PC.

In general, the remote control is currently used as a remote controller of many home appliances. However, since the signal system varies depending on the type of semiconductor applied to the infrared remote controller, the home appliance had to have a separate remote controller for the device. Therefore, when there are many home appliances, it is inconvenient to manage each remote control because a plurality of remote controls must be used. To solve this, a universal remote controller has been developed that integrates multiple remote controllers into one. However, even using such a universal remote control, it is difficult to apply to new home appliances, etc., and has a disadvantage in size and weight. In particular, since the home universal remote control can be used by the whole family, even if the remote control is integrated with a plurality of remote controls do not know the place where it can be a lot of time to find a remote control when needed.
