Abstract: The present invention relates to distributed and self-configuring instrumentation in home and office environments. The object of this invention is to obtain a reduced cost distributed building automation instrumentation system in home and office environments with distributed autonomous operation capabilities, including support for modifying and adapting system operation to user preferences, assuring assembly security. To that end, the present invention proposes using commonly used components for designing a non-proprietary instrumentation network (1,3,7) and constructing terminal nodes (2) for the instrumentation (4,5,9,10) which facilitate connecting generic devices (10). The present invention proposes mechanisms aimed at improving the installation, configuration, operation, security and autonomy of the instrumentation network, as well as a central node (6) as support in network initialization, configuration and management tasks.
