5.2.4.1 Description

Innovative services can be developed from the data (energy) collection and sent to either the consumers/
equipment or to Business-to-Business market.
The use case focuses on a home gateway that collects energy information from the electrical home network
and communicates it to an IoT system for aggregating and processing of the data. Services can then be
developed from the collected data.

The home gateway performs an initial treatment of the data received from various sources (sensors, context)
as follows:

• Aggregating and processing the obtained information;
• Sending some information to the remote service platform e.g. sending alerts;
• Using some information locally for immediate activation of some actuators/appliances;
• Connected (wirelessly or via wireline) to home devices, including the home electrical meter, for
information on global or individual consumption of the appliances;
• Providing displayable consumed energy-related information to the end-user/consumer terminals
(PC, mobile phone, tablet, TV screen, etc.).

5.2.4.2 Actor list
User: user of home appliance who are able to control home appliance using terminal device (e.g. laptop,
smartphone, etc.)

Home appliance: appliances which may be from multiple vendors
Home Gateway: a device installed in the user’s home and receives remote control commands from the
management server
Communication operator (LAN/PAN/WAN): in charge of communicating the collected information via any
protocol (e.g. ZigBee, Power Line Communication (PLC), Bluetooth 4.0, Wi-Fi, etc.)
Service Server: in charge of providing services/common functionalities for applications

5.2.4.2 Analysis

Trusted data collection and aggregation
Data should be trustworthy from devices (home appliances) to home gateway and gateway to service
platform. Devices produce data, and data is collected in a gateway and service platform. When data is
produced and transmitted to other entity, trustworthiness of data is required to be maintained.
