KNX:
KNX is the standard that allows the automated and decentralized management of the technologic plans of
a big typology of structures: commercial buildings, factories, houses, public locals, schools and so on.
KNX can be used in all the applications and functions for the building automations: from lighting to control
dampers, to the security, to the heating monitoring, to the conditioning, to the hydric control and alarms,
to energy management and so on.
