Introduction
The objective of this European Standard is to specify how sets of products from multiple manufacturers are
able to interoperate and be installed with or without the use of a special tool, in the most automatic manner.
By meeting this standard, future household appliances will be able to enjoy a significantly larger market.
Figure 1 shows what it takes to obtain interworking between household appliances:
• the Household Appliances Interworking standard. It is highly independent of the underlying protocol;
• a protocol for communication between devices in the home;
• a mapping scheme from the Household Appliances Interworking standard to each selected protocol.

3 Installation of a system
3.1 Definitions
3.1.1 Phases of Installation
Installation of WG appliances with home networking capability consists of two main phases:
• initialising specific network protocol data:
- house address or domain address. This value is used on open media (e.g. power-line or RF) to
recognise network messages within the same home unit. It is necessary to make sure appliances do
not receive messages coming from different homes;
- network address of the appliance being installed. A network address serves as a "unique" identifier
for an appliance on a network. Appliances can determine the addresses of other appliances on the
network and use these addresses to send messages to each other;
• initialising communication links data, basically consisting of the network address of remote devices.
3.1.2 Plug & Play Installation
An installation which is fully automatic, i.e. which does not require user intervention is said to Plug & Play.
3.1.3 Plug, Touch & Play Installation
An installation, which is based on a limited sequence of simple user actions (i.e. Plug, Touch & Play).
3.2 Rationale for Installation in WG Appliances
3.2.1 Installation Approach for Household Appliances
In general, it is expected that WG appliances installation will be simple, protected and secure. The installation
procedures should be such that the user without the intervention of a specialised installer can perform it. In
particular, it could be either fully automatic (i.e. Plug & Play), or explicitly started and handled in a simple way
by the user, for example using a combination of buttons to start the procedure and relying on some LED
feedback (i.e. Plug, Touch & Play).
The limited sequence of user actions will typically be used for two purposes:
• getting the domain address. To this end, a touch sequence or another interaction will be typically
available to the user. The objective of the touch sequence is to direct another appliance to provide the
domain address information. In principle any already installed appliance can provide this information. In
practice, a dedicated appliance such as a gateway will be used for this purpose;
• handling the case of more than one WG appliance of the same type in the same home (e.g. two washing
machines). When such a case happens, there is a need to distinguish the appliances from a networking
point of view, in order to allow a home controller to access individually. This function is called "Instance
Identification". To this end, a touch sequence will be typically available to the user or another mechanism
in order to indicate it.
The figure below shows the interactions which are expected during installation. To achieve installation, the
appliance is interacting with another cooperating device. It will be involved in four phases, shown in
rectangles:
1) getting the domain address;
2) automatic installation phase;
3) optional instance identification;
4) providing installation feedback.

Figure 2 – Expected Interactions during Installation
The implementation of these four phases is completely open to the manufacturer. It is recommended that
• the sequence of actions to get the domain address should conform to the related protocol (interaction 1
in Figure 2),
• the automatic part should conform to the related protocol (interaction 2 in Figure 2). Note that the figure
was simplified as the automatic procedure could also take place before and after the sequence of
actions,
• the section of actions to implement instance identification should conform to the related protocol
(interaction 3 in Figure 2),
• the semantics of the feedback display should conform to the semantics of the installation protocol.
Therefore, it is expected that in practice there will still be many different approaches used for installation:
• the way to accomplish the installation actions at the level of the appliance could change from one
appliance to another, as long as the objective of such actions and the related protocol are the same (e.g.
a different combination of touch buttons is used);
• the actions to take at the level of other devices could be very different. They could involve different
devices from one installation to another (e.g. a specific controlling device with a user interface, a
gateway with specific installation buttons, a specific temporary tool), as long as the achieved objective
and the involved protocol are the same. For instance, it is possible that within the home system an
Installer device can be used to supervise installation and operations of other appliances. This specific
device could then be responsible for domain address provision, for the handling of multiple appliances of
the same kind (for example two washing machines on the same system). It could further support some
routine to verify that a new appliance is not installed on different or wrong environments (for example an
appliance being installed on the neighbour system).
Consequently, even though user intervention could be different for each manufacturer, it should use the same
network management protocol. This will ensure that interoperability can be insured.
3.2.2 Constraints
It is expected that a number of constraints related to installation procedures will be typically met in order to
put Household Appliances with networking capability on the market.
• Appliances with networking capability should also work even when they are used as autonomous system
without communication during their lifetime. The transition from and to autonomous modes must be
transparent to the user and should not require user interventions.
• Installation procedures
- should not depend on specific communication technology aspects,
- should be clearly presented (for instance in the case of combination of buttons),
- should allow the manufacturer to be free in the choice in their implementation,
- should support domain address acquisition. Without this capability, a filter separating
1)
communication would be needed in each home ,
- should give a chance to every appliance to be linked,
- should have a duration that is minimised,
- should take into account appliances that may be switched off (such as washing machines).
• User interfaces for installation procedures
- should be easily accessible,
- should have minimised costs. As an example, a solution based on one push button and one LED
seems to be correct from the point of view of the price.
• Regular checking of communication links integrity is expected in order to maintain consistent
configuration data upon events such as appliance removal, switch on or communication failure (note that
it is not obvious to distinguish such events). This point is particularly difficult because it is application
related and therefore seems to be difficult to standardise.
3.3 Key Installation Events and related User Functions
Household Appliance installation procedures shall follow a common scenario and common rules. More
precisely, the procedures shall be described through the same list of key events concerning the whole
installation. Each key event shall be associated with user functions.
The following table defines the key events concerning the whole installation.
1)
Even then, cross talking could happen.
– 13 – EN 50523-1:2009
Table 2 – Key Installation Events
Key event Description
First installation First time communicating appliances are installed in a home. For instance,
a gateway and a washing machine are installed.
Power Up Powering up one or several appliances (e.g. powering up the whole
installation after power failure).
Appliance is added A new appliance is added to the home installation. In some cases the
appliance could have been used in an autonomous mode (i.e. without
networking capability) for some time.
Appliance is removed An existing appliance is removed from the home installation (this could be
because the appliance is physically removed or because the appliance gets
back in an autonomous mode without networking capability).
Appliance Part of the installation is re-installed.
Re-installation
Re-installation The whole home installation is re-installed.
De-installation The home installation is de-installed. This could take place when persons
are moving out from their home.
Monitoring of A verification of the communication links is performed.
Communication Links
The following user functions in Table 3 are associated with each key event. In the following configuration,
data refer to network protocol data and configuration links data.
Table 3 – User Functions associated with Key Installation Events
Key event User function
First installation
Installation creation
The overall installation is created and personalised (i.e. a domain address
is assigned). An installation feedback is provided to the user.
Communication function is enabled with optional feedback to the user.
Power Up Automatic power up verification
After power up of one or several appliances, a short automatic start-up
phase takes place, involving the verification of its configuration.
Appliance is added Adding an appliance
The installation configuration is updated with a new communicating
appliance (i.e. configuration data of appliances are updated).
Appliance is removed
Removing an appliance
The installation configuration is updated to take into account removal (i.e.
configuration data of appliances are updated).
Re-installation
Re-installation
Network configuration data is changed in all the appliances or in a subset
(i.e. get domain address and dependent data).
De-installation De-installation
Network configuration data are removed from all appliances in the
installation (i.e. remove domain address and dependent data).
Monitoring of the Verification of configuration data
Communication links
Configuration data are verified.
Removing a specific communication link
In some cases, communication links might be considered as frozen once
they are set (this would be the case of an appliance that is usually switched
off). It is therefore necessary to specifically indicate when an actual removal
has taken place (e.g. with an appliance that is switched off).
3.4 Guidelines on Installation Procedures
3.4.1 Requirements
The following requirements are defined concerning installation procedures.
• Requirements on user functions. The following user functions shall be supported:
- installation creation;
- communication function enabling;
- automatic power up verification;
- adding an appliance;
- removing an appliance;
- re-installation;
- de-installation;
- verification of configuration data;
- removing a communication link.
• Requirements on installation actions. While each manufacturer will have the choice of their
implementations, such actions shall use as many existing elements of appliances as possible (e.g.
button, LED), except if the desired element does not exist. The minimum shall be the following: one
Boolean actuator such as a button (to perform the actions) and one Boolean display LED (to visualise
the status). Note that using a combination of buttons is considered reasonable.
• Requirements on feedback. The display of the status of each WG appliance in terms of installation shall
be mandatory. Each manufacturer will have the choice of its implementation.
• Requirements at the interworking level. WG appliances shall interwork at the installation level.
• Requirements at the installation level. Installers will have the choice of the installation scheme in terms
of involved devices, installation action and user interface. The minimum shall be an installation without
any tool.
3.4.2 Installation Functions
Installation functions are the procedures required to carry out user functions. Two types of such procedures
are defined:
• automatic: These procedures shall be supported by the network management part of the underlying
protocol as shown in Figure 2. As a result, this document only provides a functional description of these
procedures, while the protocol part is being described in specification documents related to the selected
underlying protocol.
• user: These procedures involve user action and a protocol part. Similarly to automatic procedures, the
automatic part of the user procedures shall be supported by the network management part of the
underlying protocol. The user action part shall be supported by the WG appliances through an
appropriate
