The Niles speakers surrounding this pool are part of an Élan whole home automation system that provides music from sources such as Pandora, worldwide internet radio stations, a cable receiver and iPods. The system also provides music to almost every room in the house and can be controlled from handheld remotes, wall-mounted touch screens and mobile devices such as iPads and smart phones. In addition to controlling the music, the system also controls the lights in the backyard, the hot tub and even allows the doorbell to interrupt the music and play through the speakers when someone is at the door.
