Abstract
An electrical appliance (100) comprises a digital control system (SC), configured for enabling the performance of a plurality of pre-determined basic functions, and an auxiliary device (200) comprises means (PM, 230-231) for acquiring and/or processing auxiliary information. The electrical appliance (100) and the auxiliary device (200) moreover comprise respective communication means (270), for setting up between them a bi-directional communication of data. The control system (SC) of the electrical appliance (100) is provided for enabling execution of additional functions with respect to the basic functions and for sending to the auxiliary device (200), via the communication means (270), requests for auxiliary information, necessary for the performance of said additional functions. The auxiliary device (200) is pre-arranged for communicating to the control system (SC) of the electrical appliance (100), via the communication means (270), the auxiliary piece or pieces of information requested, as processed and/or acquired by the device itself.
