Cooperative Interface Avoidance for Home Automation Controllers

      Common medium results in conflicts and interference when
multiple Home Automation (HA) systems reside on the same power line.

      This article describes a way to resolve this problem by
executing a pre-defined exchange of configuration information from
the various HA systems connected to the common medium.  The
methodology used to alleviate interference between multiple HA system
is one of cooperative interaction between the different systems.

      The basis for the article is the ability of the HA system and
it's associated software application to exchange information about
each of the different systems.  The systems architecture is defined
in such a way as to survey the power line, when first powered on,
looking for other systems.  If another system is found to be resident
on the common power line, the systems go to a mode of operation where
information is exchanged between the systems.

      Information is gathered about each system and then displayed to
the users so informed decisions can be made about the expected power
line activity.  The information that is exchanged is dependent on the
configuration of the systems involved, but basic information such as
the default address setting would be exchanged in all cases.  With
this basic information, the users can determine how best to setup and
use their HA system for maximum flexibility without interfering with
other HA system...
