Introduction
Energy management systems will more and more become necessary due to change from fossil and nuclear
to renewable production and the associated decentralization. Since an appropriate standard for a home and
building management is in preparation this document specifies how sets of products from multiple
manufacturers can exchange information with Home and Building / Customer Energy Management Systems,
located in a home network or in the cloud.
This document focuses on interoperability of household appliances and describes the necessary control and
monitoring. It defines a set of functions of household and similar electrical appliances. The functions in this
document cover next to energy-management main remote-control and – monitoring use cases.
This document does not deal with safety and security requirements. Safety requirements have been set in the
IEC/EN 60335 series [1].
EN 50631 will provide interoperability on information exchange among various appliances in the home. The
EN 50631 series will be re-arranged regarding the further development and will be split into 6 parts:
— EN 50631-1, Household appliances network and grid connectivity — Part 1: General Requirements,
Generic Data Modelling and Neutral Messages
— EN 50631-2, Household appliances network and grid connectivity — Part 2: Product Specific mappings,
details, requirements and deviations
— EN 50631-3-x, Household appliances network and grid connectivity — Part 3: Specific Data Model
Mapping
— EN 50631-4-x, Household appliances network and grid connectivity — Part 4: Communication Protocol
Specific Aspects
— EN 50631-5, Household appliances network and grid connectivity — Part 5: General Test-Requirements
and - Specification
— EN 50631-6, Household appliances network and grid connectivity — Part 6: SPINE Data Model Toolbox
Data communication heavily depends on the environment of appliances. Sometimes low bitrate or energy
efficient communication puts strict requirements to selected communication technologies. Therefore, popular
and de facto standards had been and will be developed by the industry to fulfil such requirements. To not
influence common data modelling for appliances because of such restrictions, the standardized data models
and neutral message structures need to be applied to communication technologies.
This standard series therefore is intended to separate data modelling and neutral message structure from the
attached communication.
Part 1 defines general requirements, generic data modelling and generic neutral messages without relation to
any specific communication technology or any product specific layout.
Part 2 lists and specifies product specific requirements and implementation guidance based on the generic
data model and generic neutral messages.
Part 3 defines the mapping of neutral messages to examples of typical data models like SPINE, OCF, and so
forth. These data models are neither mandatory nor to be seen as complete spectrum of data models.
Part 4 defines the mapping of neutral messages to examples of typical communication protocols. These
communication protocols are neither mandatory, nor do they provide an exhaustive list of communication
protocols.
Part 5 defines testing requirements and testing specifications. This part will be covered in the future by a New
Work Item Proposal.
Part 6 provides the technical reference specification for the SPINE data model. This part will be covered in
the future by a New Work Item Proposal.

1 Scope
This document specifies the application of relevant transport protocols for Home and Wide Area Networks as
well as cloud connectivity; in this case, SPINE (Smart Premises Interoperable Neutral-Message Exchange),
SPINE-IoT, and SHIP (Smart Home IP).
This document is part of the EN 50631 series, which defines the information exchange between Smart
Appliances and management systems in homes and buildings including energy management.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
CA
Certificate Authority
Certification Authority
entity which can provide a digital signature for certificates
Note 1 to entry: Other SHIP nodes can check this digital signature with the certificate from the CA itself, the “CA-
certificate”.
3.2
Commissioning Tool
instrument to establish the trust between different devices in the smart home installation, e.g.
distribute trustworthy credentials from some SHIP nodes to other SHIP nodes
Note 1 to entry: E.g. a smart phone, a web server or a dedicated device can embody the role of a commissioning tool.
So far, the SHIP specification does not specify a commissioning tool; an interoperable protocol for commissioning can be
used on the layer above SHIP.
Note 2 to entry: A manufacturer may also use their own solutions.

2. O = optional
3. NV = not valid
4. C = choice, i.e. a presence or support depends also on the selection from multiple possibilities
