Communications Systems

Activities and Goals

The main goal of this work-package was to establish communications solutions for in-building communication with the AnyPLACE solution and for wide area network communication outside the building and a service oriented reference architecture for the modular AnyPLACE platform. Low level communications requirements were identified for an adaptable smart metering platform with active service exchange.

Key Findings

A modular communications architecture for the AnyPLACE solution can be designed according to technical, regulatory and non-functional communications. A service-oriented reference communication architecture was established in accordance to the functionalities and services identified for the AnyPLACE solution. Different technologies for wireless and wired communications were analysed for usability in the AnyPLACE context.

An OpenHAB based middleware was found to be suitable for a broad variety of protocols supported as part of the modular approach to connect as many different smart home, smart metering and similar systems and solutions. OpenHAB bindings to connect different appliances and metering devices could be developed. With the meter-related OpenHAB bindings developed for the Portuguese and German Smart Meters and Smart Meter Gateway HAN interfaces, the end-user can receive consumption data via an energy management platform such as the AnyPLACE platform, using meter equipment which has already been rolled-out by the MSO or DSO. Thus, the end-user does not have to purchase additional metering equipment costing e.g. €200, but can use the HAN interfaces of existing smart meters.

For Wide Area Network connectivity, an LTE based solution for areas with a low percentage of cable-connected households can be developed according to the defined ICT requirements. This was tested using an LTE SMGW for the secure connection with Metering System Operators and Distribution System Operators. An Xbee-based solution was integrated in Bosch Water Heaters to establish in-house connectivity with the AnyPLACE platform and a respective OpenHAB binding was integrated.

Conclusion

A lack of common regulations on in-home communication protocols as well as of European metering communication architectures leads to a need of modularity which reduces cost-efficiency and ease of use. The regulations in Germany are very detailed while in other countries either security standards are lower or the way security is to be integrated to metering systems is not standardised. A common architecture is possible when adapting to the German concept and the country-specific amendments. A better approach would be an EU-wide common regulation.
