1 IntroductionThis document represents formal deliverable of the D3.1.2.1 “EMD Final Prototype” and provides “EMD User Manuel” – D3.1.2.2.

This document provides instructions on how to install, power up, and use the EMD device. Instructions also include EMD maintenance and configuration through the home gateway software.

The guide is divided in two chapters. Chapter 2 provides basic instructions for the EMD installation and first-time power up (section 2.1, 2.2), information on how users can access the EMD for configuration purposes through the Gateway software (section 2.3) and instructions on software definitions needed after EMD’s first-time interconnection with (a) new appliance(s). Chapter 3 gives instructions on the maintenance of the EMD software (drivers implementing APIs towards the gateway software) so that EMD can be used by the services of the gateway.

D3.1.2 AIM


2 Installation InstructionsInstallation of the various components and the needed connections between them is a rather straightforward procedure. The physical devices that take place are the (master) EMD and the gateway. The physical connections needed are gateway-to-EMD and EMD-to-powerline.

2.1 Physical connectivityThe EMD is connected to the gateway through a RS-232 serial cable (Figure 1). This connection is responsible for all the data communications between the gateway and the EMD.

Figure 1: EMD-Gateway serial connection.

The EMD is communicating with the various home appliances using the existing powerline network. For that reason, its physical interface is an existing electricity plug of the house (Figure 2).

AIM D 3.1.2


Figure 2: EMD-powerline connection

Finally, we should not forget to plug the gateway to the mains and provide a network connection that will make its services accessible over the TCP/IP network. Figure 3 illustrates an overview of all the connections needed.

Figure 3: Physical connectivity overview.

2.2 First-time power upThe first thing that needs to be switched on is the gateway device. This is accomplished by pressing the ON/OFF button existing at the front of it. Normal operation is indicated by a switched on blue led at the front panel (Figure 4).

AIM D 3.1.2


Figure 4: Switching on the gateway.

After switching on the gateway, a short period of 2-3 minutes must pass in order for the system to boot and the various services to start properly. After that period, the EMD is switched on by plugging it to the powerline network. No button needs to be pressed for the EMD to start functioning. Normal operation of the EMD is indicated by an orange blinking led (Figure 5).

Figure 5: Switching on the EMD

When the EMD is plugged in, it communicates with the gateway over the serial connection in order to “pair” their operation and listens for requests over the powerline network. Those requests may have to do with registration of new KNX devices or other data returned from the various home appliances.Also, the EMD forwards requests, initiated by the gateway, to the existing registered devices.

2.3 User connectivity

2.3.1 Users registration

User registration is an operation allowed only to an administrative user. Thus, after logging in asadmin, user will be presented with the following screen,

Figure 6: Administrator’s management page

By selecting “User Accounts Management” the admin can register new users,

2.4 Appliances installation

2.4.1 Profiles

Each home appliance is advertised by the Machine-to-Machine (M2M) sub-system with a unique device ID. This ID is used in order to correlate a device with an appliance profile. Appliance profiles are structured documents represented in XML format. These documents describe all the functionality that a device supports; that is actions, variables and events. At the “Install New Device” menu the user is presented with the following screen,

AIM D 3.1.2


Figure 9: View of installed devices

On the left side of this page the user is presented with the “Existing Devices”. These are the devices that have already been installed. The information presented here is the M2M ID of the device, the name that was contained in its profile during installation and its Status as returned by the M2M interface. On the right side, he is presented with all the M2M-advertised devices that have not yet been installed,

D3.1.2 AIM


Figure 10: M2M ID selection

After selecting a M2M device ID, user must also select the XML profile that will describe this device. The “Install” button finishes the installation procedure and an informative message is presented to the user.

AIM D 3.1.2

2.4.2 Appliance connectivity

The details for the physical connectivity of each home appliance depend on the very nature and capabilities of the device itself. First of all, all KNX-over-powerline-ready devices can participate in the network and will be fully accessible by the (master) EMD. As long as they are supported by the M2M interface, they are also going to be advertised by it and will be ready for installation as described in 2.4.1. So, for KNX-ready devices the only thing needed is to plug them to the wall.

Now, for the cases that the appliance is not KNX-ready, a (slave) EMD device is needed. The EMD here has a double role. The first role is to measure the current that the device is consuming and the second one is to communicate the data from the device to the home network and vice versa. For devices that do not expose any specific communication interface, the connection is rather simple. Such a case is like the one shown in the following figure,

D3.1.2 AIM


Figure 12: Simple device made KNX-ready

Here, the EMD is sitting in front of a normal desk-light. The light’s electricity input is from the EMD and the EMD is connected to the mains. Here, the EMD can only respond to requests about the current consumed by the light and to TRIAC ON/OFF commands.

A more complex scenario is like the one in the following figure:

AIM D 3.1.2


Figure 13: Complex device with specific interface made KNX-ready

Here, the EMD acts as a mediator of communications for a washing machine. Apart from the power supply that the washing machine is taking from the EMD, another, serial connection is made between them. The reason for this is that this washing machine exposes a well-known communication interface that supports specific functionality, such as setting the program, starting/stopping the cycle, getting the washing phase. So, in this case, the EMD can respond not only to requests about the current consumed but also about more complex operations. These operations can be sent to the washing machine from any place inside the KNX network. Firstly, KNX messages are transmitted over the powerline from the other home appliances. These messages are then are caught by the (slave) EMD. The EMD strips the KNX-specific information from the message and what is left, which should be data compliant to the device’s specific interface, are forwarded through the serial cable to the device itself in order to be processed and/or executed.

Current M2M implementation distinguishes simple KNX-ready devices like the desk-light from complex KNX-ready devices like the washing machine. For the first type of devices (Generic KNX devices) a limited interface will be accessible, such as getting the current consumed, switching the TRIAC ON and OFF, getting the status of the device (ON/OFF). For the second type of devices like the Indesit washing machine a richer interface is provided which extends the interface of the generic KNX devices. The extended functionality has to do either with new features such as the acquisition of the washing phase or temperature, or with the enrichment of existing ones such as the status of the device which instead of being only ON/OFF, can return the actual state of the washing machine(Running, Idle etc.).

D3.1.2 AIM


All these devices are advertised by the M2M interface and can be installed in the home network as described in 2.4.1.

AIM D 3.1.2


3 System maintenance

3.1 Software maintenance and upgradeAll the functionality needed by the EMD is installed in the gateway in the form of OSGi bundles. This creates a very easy to use maintenance/upgrade facility. When the user needs to upgrade the EMD software, he just uninstalls the older versions of the bundles and installs new ones. This procedure is accomplished through a web interface by selecting the “Software Update” option from the main menu,

Figure 14: Software update administration page

Here the user can administer the whole OSGi environment. He can start/stop any bundle, uninstall old ones, install new versions or bundles that contain new functionality or extend the existing one, acquire information for an installed bundle. Again, this page will be accessible only to an administrative user, because the various bundles presented here are vital for the proper operation of the EMD and the gateway, so mistakes in operation of this environment can damage the system.

4 ConclusionsThis document represents formal deliverable of the D3.1.2.1 “EMD Final Prototype” and provides “EMD User Manuel” – D3.1.2.2. Accordingly, it gives instructions for the installation and software/hardware configuration of the EMD, so that it can be used by the AIM services.

For reasons of respecting timing in the submission of this report, the photos shown above have been taken using the interim prototype EMD version, because by the time of this writing the final EMD prototype is under manufacturing to ensure reduced size and commercial-grade outlook.

Nevertheless the first final EMD prototypes have been tested with real appliances and were found compliant with the communication requirements set out in D2.1.

The next step that follow WP3 conclusion is the implementation and pilot operation of AIM services in the context of WP4. According to the timing set in the last plenary meeting in Fabriano (20-21 October 2009), laboratory tests involving the EMD, the gateway and the WP4 applications will be carried out until end of December 2009 in Italy (Cefriel and Indesit premises), while from the next year and onwards the final system will be delivered to France Telecom and BCT for installation in real home environments.
