Abstract
A remote control system (100) includes a home appliance (10) and a relay device (20, 30) for relaying transmission of an operation instruction for controlling the home appliance (10). The home appliance (10) includes a first detector for detecting a communication interruption on a first communication line (41, 42) for transmission of the operation instruction from the relay device (20, 30) to the home appliance (10), a receiver for receiving, from the relay device, an interruption signal indicating a communication interruption on a second communication line (42, 43) for transmitting the operation instruction from a communication device to the relay device (20, 30), and a state changer for changing a state of the home appliance in accordance with a duration of at least one of the communication interruption detected by the first detector or the communication interruption indicated by the interruption signal. The relay device (20, 30) includes a second detector for detecting the communication interruption on the second communication line (42, 43), and a transmitter for transmitting the interruption signal to the home appliance (10) when the communication interruption is detected by th…
