PURPOSE: A wireless bi-directional home automation system is provided to allow IDs to controlled apparatuses at home to control the apparatuses by using telephones or PCs from an exterior and to confirm controlled results, so as to bidirectionally control the apparatuses through a public switched telephone network(PSTN), a cellular network, and an internet network outside the home, or to control the apparatuses by using the telephones or the PCs inside the home. CONSTITUTION: A user connects a call with a telephone(36) equipped at home through a public switched telephone network(PSTN)(20), by using a telephone(10) from an exterior. A memory(31) of an interface module(38) pre-stores controlled contents. If the telephone(36) is not connected for a regular time, a micro computer(32) transmits the stored contents to the user. If the user presses a number corresponding to the contents, data of the number is wirelessly transmitted to a wireless transceiver(41) of a controlled device control module(40). The data is analyzed by a controlled device control micro computer(42). A controlled device driver(43) is controlled by a control signal of the micro computer(42). The micro computer(42) confirms whether a command is performed. If a performed result is transmitted to a wireless transceiver(33) of an interface module(30), a voice prestored in the memory(31) is transmitted to the user through an interface(34) of the interface control module(30) and the PSTN(20).
