KNX Package 2.0
The ProSyst KNX package provides an OSGi-integrated API to accessing devices connected via KNX - the
worldwide open standard for home and office building control. The features included in the KNX package allow
the users to connect and communicate over the KNX network and to manage appliances such as lighting, blinds /
shutters, security systems, energy management, heating, ventilation and air-conditioning systems.
