After adding at least one picture you can open it in the Gallery and control the luminaires in it. Tap on a picture to open it in full screen. Note: Scenes or groups associated with luminaires in the picture will be displayed under the picture. The scene icon is shown even if just one luminaire in the picture is part of the scene.
Use the normal gestures to control the luminaires in the picture. If the gestures are used over individual luminaire icons then only that luminaire will be controlled. If you use gestures by selecting an area of the picture that does not have icons, then you will control all luminaires in the picture that have icons associated with them.
