Updated PSSCs An ability to detect a user based on RFID and determine which user has priority, displaying the user's identity on an LCD An ability to adjust the light intensity to match a user’s settings through X10 protocol An ability to adjust a television set or other HDMI device using CEC- HDMI protocol, to a user's preferred settings. (ON/OFF, Channel, Volume) An ability to unlock a door when an acceptable RFID is present An ability to select/set preferred settings through an embedded web server and the ability to save the "light settings" with the press of a button.
