A method for controlling a communications terminal that controls an illumination device via a network , the communications terminal including a computer, a memory , and a sensor that senses a motion of the communications terminal , the method comprising: causing the computer of the communications terminal to store a user's wake-up time in the memory ; causing the computer of the communications terminal to store first illumination setting information in the memory , wherein the first illumination setting information is used to set the illumination device to a first illumination state before user's wake-up; causing the computer of the communications terminal to store second illumination setting information in the memory , wherein the second illumination setting information is used to set the illumination device to a second illumination state after user's wake-up that is different from the first illumination state and represents a setting value of at least one of an illuminance, a wavelength, and a light pattern of the illumination device and is settable in advance by the user of the communications terminal ; causing the computer of the communications terminal to transmit, at a certain illumination start time at which the illumination device is to be turned on, a first control signal corresponding to the first illumination setting information to the illumination device via the network such that the illumination device is set to the first illumination state, wherein the illumination start time is determined on the basis of the user's wake-up time; and causing the computer of the communications terminal to transmit, in a case where user's wake-up is detected through a motion of the communications terminal sensed by the sensor after the certain illumination start time has passed, a second control signal corresponding to the second illumination setting information to the illumination device via the network such that the illumination device is set to the second illumination state. causing the computer of the communications terminal to store a user's wake-up time in the memory ; causing the computer of the communications terminal to store first illumination setting information in the memory , wherein the first illumination setting information is used to set the illumination device to a first illumination state before user's wake-up; causing the computer of the communications terminal to store second illumination setting information in the memory , wherein the second illumination setting information is used to set the illumination device to a second illumination state after user's wake-up that is different from the first illumination state and represents a setting value of at least one of an illuminance, a wavelength, and a light pattern of the illumination device and is settable in advance by the user of the communications terminal ; causing the computer of the communications terminal to transmit, at a certain illumination start time at which the illumination device is to be turned on, a first control signal corresponding to the first illumination setting information to the illumination device via the network such that the illumination device is set to the first illumination state, wherein the illumination start time is determined on the basis of the user's wake-up time; and causing the computer of the communications terminal to transmit, in a case where user's wake-up is detected through a motion of the communications terminal sensed by the sensor after the certain illumination start time has passed, a second control signal corresponding to the second illumination setting information to the illumination device via the network such that the illumination device is set to the second illumination state. <EOS>
