DIN EN 50631-4-1:2024-09

Due to the transition from fossil fuels and nuclear energy to energy generation using renewable energy sources, and the associated decentralization, the demand for energy management systems is increasing. As a suitable standard for home and building management is in preparation, this document specifies how groups of products from different manufacturers can exchange information with home and building/customer energy management systems located in a home network or the cloud. This document focuses on the interoperability of household appliances and describes the necessary control and monitoring. It specifies a set of functions for household and similar electrical appliances. In addition to energy management, the functions in this document include main use cases for remote control and monitoring. This document is part of the EN 50631 series of standards, which defines the exchange of information between smart household appliances and management systems in residential and other buildings with energy management. The EN 50631 series of standards is being reorganized with a view to further development and will consist of six parts. This part specifies the application of relevant transport protocols for Home and Wide Area Networks as well as cloud connectivity; in this case SHIP (Smart Home IP). Data communication is highly dependent on the environment of household appliances. Sometimes, low bit rates or energy-efficient communication place strict demands on selected communication technologies. Therefore, widely used and general standards have been and continue to be developed by the industry to meet such requirements. In order not to influence the common data modeling for household appliances by such restrictions, the standardized data models and structures of the neutral messages shall be applied to communication technologies. This series of standards is therefore intended to separate data modeling and the structure of neutral messages from the associated communication. Part 4 defines the mapping of neutral messages to examples of typical communication protocols. These communication protocols are neither mandatory nor do they constitute a complete list of all communication protocols. This document does not address safety requirements. Safety requirements have been introduced in the IEC/EN 60335 series of standards.
