Control method for information apparatus and computer-readable recording medium

A non-transitory computer-readable recording medium which stores a program to be executed by an information apparatus having a display and being connected to a network, one or more target devices being controlled over the network, the program causing a computer of the information apparatus to:

• display a first display screen representing a floor plan for a first floor of a building on the display when the first display screen is selected, device icons representing the one or more target devices being displayed on the first display screen representing the floor plan for the first floor, and the floor plan for the first floor including a staircase;
• display a second display screen representing a floor plan for a second floor of the building different from the first floor on the display when the second display screen is selected, device icons representing the one or more target devices being displayed on the second display screen representing the floor plan for the second floor, and the floor plan for the second floor including the common staircase as the staircase included in the first floor;
• switch between display of the first display screen and display of the second display screen displayed on the display, when selection of a region corresponding to the staircase on the floor plan for the first floor or the floor plan for the second floor is sensed;
• and
• output to the network a first control command, when selection of an illumination icon representing an illumination device among the one or more target devices in a region corresponding to the staircase included in the first display screen is sensed, or when selection of an illumination icon representing the illumination device in a region corresponding to the staircase included in the second display screen is sensed, and when selection of the region corresponding to the staircase is sensed, the first control command controlling on/off of power for the illumination device that is associated with the region corresponding to the staircase.
