Appliance remote control

A remote control interface unit, comprising:

• an applications program configured for execution on a smart phone, said applications program configured to store in said smart phone a transmitted user identification value, an appliance identification value, a list of appliance control codes, and a list of control code restrictions for limiting appliance functions for said transmitted user identification value by an appliance with said appliance identification value;
• a processor;
• a memory connected for data communication with said processor;
• a stored user identification value stored in said memory;
• said appliance identification value further stored in said memory;
• a radio frequency transceiver connected for data communication with said processor, said radio frequency transceiver configured to receive a radio frequency signal including an appliance control code from said list of appliance control codes and a transmitted user identification value;
• and
• an optical frequency interface connected for data communication with said processor, said optical frequency interface comprising a transmitter including a light emitting diode, said transmitter configured to output from said light emitting diode an optical frequency signal including said appliance control code;
• wherein said processor is configured to extract said appliance control code from said radio frequency signal, send said appliance control code to said optical frequency interface, and initiate transmission to said appliance having said appliance identification value by said light emitting diode of said optical frequency signal including said appliance control code when said stored user identification value and said transmitted user identification value are a same value.
