Fecha de publicación: -- Fuente: Wipo "IOT" Provided is a method for controlling IoT devices using calls between artificial intelligence (AI) devices to conveniently control an IoT device on a network regardless of compatibility between the IoT devices and the AI devices. According to the present invention, the method comprises the following steps by a first AI device: outputting a feedback signal in response to receiving a call command signal of the first artificial intelligence device from a user and monitoring whether a command signal for controlling an IoT device is received; analyzing the command signal in response to receiving the command signal and extracting IoT device information and command information from the command signal; searching for the IoT device information in a stored controllable IoT device group; outputting a call command signal of a second AI device according to non-detection of the IoT device information in the stored controllable IoT device group; and outputting the command information in response to receiving the feedback signal from the second AI device to allow the second AI device to control the IoT device according to the command information.
