Furthermore, the Eve Button features three actions: single press, double press, and long press, and you can assign three scenes to your Eve Button, which allows you to control multiple devices, for instance, single press for your “Evening” scene, which turns on your lamp and shuts the shades, or double press for “Relaxation” scene that delivers soft illumination with comfortable music.
