Two driving forces
 Own protocol (Yet
Another…)
 Own technology
 Asymmetric
interoperability
 Vertical solution
(from apps to
devices)
 Who cares about
protocols?
 Use neutral
representations
 Loose coupling
between applications
and home automation
technologies
 Mix and merge of
technologies

Intelligent Domotic Environment
(IDE)

 “An environment setting in which
existing automation technologies
are interfaced by a low cost
device (gateway) providing
neutral access to the environment
for interoperation, intelligent
automation scenarios, energy
saving, etc.”

Neutral modeling

Bruxelles

 Represent the environment as perceived by
human inhabitants (i.e., in a technology
independent way)
 Describe the environment setting
 Rooms, doors, walls, etc.
 Describe devices by modeling
 What they can do (commands)
 What they can notify (values, status changes,
alerts,…)
 In which condition (state) they can be (e.g., on or off)
 Support implicit identification
 E.g., the lamp on the drawer…

 Our solution to Neutral modeling
 Declarative modeling of
 Environment
 Devices
 Functionalities (What they can be required to do)
 Notifications (What they can notify)
 States (In which condition they can be)
 Technology independent
 Extensible
 Based on Semantic Web technologies
 OWL
 SPARQL
 Inference

DogOnt

 Stems from
 EHS taxonomy
 DomoML
 Integrates concepts from
 ZigBee HA specification
 EN50523
 ZigBee Energy@Home (experimental)

 Foundational classes (Core)
 Taxonmy roots
 Relationships
 Device-related taxonomies
 Functionalities, States,...
 Network Components
 Instances
 Specific for each smart environment

 One ontology facet to model technology
specific aspects
 dogont:NetworkComponent
 Technology dependent
 Not necessarily based on human perception
 Not necessarily human understandable
 Currently supporting
 KNX, Modbus, Echelon (web service), Zwave,
ZigBee, MyHome (Bticino), TexasInstruments
(SmartWatch)

22
 DogOnt (Core) is (can be) extended
 Using OWL-defined mechanisms
 Typically
 Ontology import
 owl:SameAs
 owl:EquivalentClass
 Available extensions
 PowerConsumption
 ZigBee
 Effects

Power Consumption
3/5/2013
Bruxelles
23
 Attaches power consumption to device state
values
 Typical
 Nominal
 Actual
 Power estimation by inference
 Device consumption in a given state
 Identify most “reliable” consumption
 Actual  actually measured
 Nominal  on device label
 Typical  at the category level

Power Consumption

Dog (Domotic OSGi Gateway)
• Off-line class library generation
• On-line configuration
• On-line model merging
Open Source
• http://domoticdog.sourceforge.n

Other Applications
3/5/2013
Bruxelles
29
 Off-line rule property checking
 E.g., conformance to design/safety rules
 On-line rule property checking
 E.g., computation of safe exits in case of smoke
detection
 Interoperation rule generation
 By exploiting ontology relationships (generates
command)
