The way into the future. The EnOcean Standard for sustainable buildings. Energy-efficient. Interoperable. Practice-proven. Self-powered wireless technology from EnOcean. Everything else is prior art. ENOCEAN IS THE KEY TO INTELLIGENT GREEN BUILDINGS. Due to the unique combination of miniaturised energy converters with reliable radio technology, these wireless sensor networks operate for decades without maintenance, are flexible, and ensure cost reductions and energy savings in buildings and industrial installations alike: n Building automation optimizes energy savings and reduces operating costs lowering total cost of ownership. It furthermore, enhances security, protection and convenience. n Wireless radio technology is essential to the success of building automation. It permits the required number, functionality and flexibility of the necessary sensors. Radio technology minimizes installation times and reduces system costs. n No batteries is a mandatory requirement for larger installations. The cost to monitor, replace and recycle batteries increases with the number of installed nodes. Batteryless EnOcean radio solutions are eco-friendly, comply with the principles of building biology, and save key resources.

Bacnet Over KNX
BACnet over KNX Wolfgang Granzer Wolfgang Kastner Automation Systems Group Institute of Automation Vienna University of Technology Treitlstraße 1-3, A-1040 Vienna, Austria {w,k} @ auto.tuwien.ac.at The Building Automation and Control Network Protocol (BACnet) has been devel- oped to provide a solution for building automation and control systems of all sizes and types. While BACnet specifies an application model as well as different routing services, the underlying network medium is not defined. BACnet messages can, in principle, be conveyed over any network. However, a number of network types are recommended in the BACnet standard. Since KNX with all its benefits has not been considered as a network medium for BACnet, we provide an approach that uses KNX TP 1 as network medium for BACnet. Additionally, a first proof-of-concept implementation is presented in this paper. 1 Introduction In [1], a standard model for all kinds of Building Automation Systems (BAS) is described. In this model, the system functionality is divided into three levels which are ordered hierarchically. At the field level, environmental data are measured and parameters of the environment are physically controlled. Automatic control is performed at the automation level whereas global configuration and managements tasks are realized at the management level. Nowadays, the standard three level functional hierarchy model can be implemented as a flatter, two-level architecture [2]. This is for two reasons. First, so called intelligent field devices incorporate more functionality than ordinary ones. Second, information technology (IT) and its infrastructure became accepted not only at the management level, but also at the automation level. -

Sneak into buildings with KNXnet/IP Claire Vacherot∗, Orange Cyberdefense, 2020 Abstract. Building Management Systems (BMS) centralize and automate essential assets in a building. They are often linked to the LAN and sometimes reachable on the Internet, exposing building automation devices and network protocols that are usually not designed to handle cybersecurity issues. The paper focuses on the BMS protocol KNX, which has been left aside by the cybersecurity community so far. We discuss its technical details and the cybersecurity concerns raised by implementations. We provide a Python library to perform basic KNX discovery, communication operations and to write advanced testing scripts. We explain how to use it through fuzzing script examples. We hope that this library will be used to find and fix vulnerabilities in building management systems and as a handy tool for other research material on BMS protocols. -
Smart Assistants for Smart Homes

Unfortunately, smart homes today are far from this vision – people who already live in such a home struggle with complicated user interfaces, inflexible home configurations, and difficult installation procedures. Under these circumstances, smart homes are not ready for mass adoption. This dissertation addresses these issues by proposing two smart assistants for smart homes. The first assistant is a recommender system that suggests useful services (i.e actions that the home can perform for the user). The recommended services are fitted to the user’s current situation, habits, and preferences. With these recommendations it is possible to build much simpler user interfaces that highlight the most interesting choices currently available. Configuration becomes much more flexible: since the recommender system automatically learns user habits, user routines no longer have to be manually described. Evaluations with two smart home datasets show that the correct service is included in the top five recommendations in 90% of all cases.
