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, on the display, a predetermined display image including i) an instruction button image for specifying a type of a target device that includes an illumination device and ii) a floor plan representing each room in a building, the instruction button image and the floor plan being displayed in the predetermined display image at a same time;
- in response to detecting a selection of the instruction button image on the predetermined display image, display, on the display, a first room in the floor plan of the predetermined display image with brightness not lower than first brightness when a first illumination device installed in the first room is in an on-state, and display, on the display, a second room in the floor plan of the predetermined display image with brightness lower than the first brightness, when a second illumination device installed in the second room is in an off-state or the second illumination device is not installed in the second room;
- in response to detecting a selection of the first room in the floor plan of the predetermined display image when the first room in the floor plan of the predetermined display image is being displayed with brightness not lower than the first brightness, erase the predetermined display image including the instruction button image and the floor plan, and display a first room screen including the first room with brightness not lower than second brightness the first room screen being displayed on the display without displaying a room in the building other than the first room at a same time;
- in response to detecting a selection within the first room screen, output to the network a first control command for turning off power of the first illumination device arranged in the first room;
- in response to detecting a selection of the second room in the floor plan of the predetermined display image when the second room in the floor plan of the predetermined display image is being displayed with brightness lower than the first brightness, erase the predetermined display image including the instruction button image and the floor plan, and display a second room screen including the second room with brightness lower than the second brightness, the second room screen being displayed on the display without displaying a room in the building other than the second room at a same time;
- and
- in response to detecting a selection within the second room screen, output, to the network, a second control command for turning on power of the second illumination device arranged in the second room, when the second illumination device is installed in the second room.
