10 Which management concerns play a role? updating application logic, monitoring & resetting system access control, security keys, secure connections Where do you find management functionality? within transformer and user devices within each device to manage itself (not shown mostly) Who owns the data? the person who owns the house What interests are there in the data monitoring energy use (owner) Questions monitoring system quality and behavior (panel owner) and typical energy use monitoring what happens at home (thief, perhaps government) Who controls the data? depends on how much seeps through the http server and whether data is encrypted storage-wise: the controllers of the stores, the policies of the store-writers, the readers of the pages What are the things? Three things can be seen: raspberry, transformer, smart meter 10

13 This is a fairly standard 3 tier architecture many websites work like this however, with an automated process of data insertion architecture alternatives are obtained by different deployment choices for components at different locations on the internet with significant impact on extra-functional properties The situation is fairly static: only clients change Comments The data can be used to analyze processes in my home: vertical analytics. For learning general things, multiple homes must be monitored and compared: horizontal analytics 13
