A wireless lighting control system includes a remote server system connected to a wide area network and having software for configuring, monitoring, and controlling lighting fixtures at an installation site. The site includes wireless devices in communication with a gateway via a local wireless network and at least some of the wireless devices are configured to control lighting fixtures, including a configurable user control device, such as a wall dimmer switch, having user interface elements configurable to activate specific lighting effects, such as power, dimming, and scene control. A user computer device is connected to the wide area network and has a graphical user interface enabling virtually mapping of user interface elements to lighting effects. Configuration can advantageously be done without physical access to either the user control device or to the lighting controllers, fixtures, or other devices at the installation site.
