This module is a part of the NetHomeServer. The X10HouseScene is used to control X10-devices via the X10Port module. The X10 protocol allows for some manipulation of all units with the same a HouseCode with single commands. For example swith off all units with HouseCode 'A'. The X10HouseScene allows access to those functions. Since the X10 is quite slow, this makes sense if you for example wants to switch off a large number of lights.
