SAREF4ENER is an extension of SAREF for the Energy domain that was created in collaboration with Energy@Home (http://www.energy-home.it) and EEBus (http://www.eebus.org/en), the major Italy- and Germany-based industry associations, to enable the interconnection of their (different) data models. SAREF4ENER focuses on demand response scenarios, in which customers can offer flexibility to the Smart Grid to manage their smart home devices by means of a Customer Energy Manager (CEM). The CEM is a logical function for optimizing energy consumption and/or production that can reside either in the home gateway or in the cloud. SAREF4ENER is published as an ETSI tecnical specificatoion (ETSI TS 103 410-1).

Independent from the ActuatorSwitch class, the ActuatorLevel class enables a user or application to model LEVEL commands (start, up, percentageAbsolute, relative, etc.). This can be used to dim a light, set the speed of an electric motor, etc.
Actuator level
Basic on/off operations on a simple actuator can be modelled with the ActuatorSwitch class. Whether the function turns a device itself ON or OFF, or whether it switches a specific feature, depends on the implementation. For example, one could model the super freeze program of a freezer using ActuatorSwitch class. An ON command would then activate the super freeze program and an OFF command would deactivate it. This example shall just give an idea how ActuatorSwitch can be used for more purposes than only turning devices on and off.

A specialization of a saref:Device that exposes a power profile with power sequences to the CEM (note that a s4ee:Device can also be called 'power sequence server'). Most of the existing devices can expose at most 1 power profile, but there are special cases in which more than one power profiles can be exposed by the same device. For example, consider the case of a combined fridge-freezer in which there are 2 logical devices (fridge and freezer) combined in 1 physical device. This combined device can expose 2 power profiles, one for the fridge and one for the freezer. A s4ee:Device (e.g. a household appliance or a smart meter) can also receive events about overload warning severity level and related load control commands (LoadControlEventData)

The specification of a task, such as wash or tumble dry, according to user preferences and/or manufacturer's settings for a certain device. It is the most 'coarse' view, a power sequence can represent all single steps of a whole task,where the single steps are represented by slots. If the power sequence is pausable by the bound power sequences client, the property 'saref:isInterruptionPossible' SHALL be present and set to true. Otherwise it SHALL be omitted. If the power sequence is stoppable by the bound power sequences client, the property 'saref:isFlexible' SHALL be present and set to true. Otherwise it SHALL be omitted.

In case the power sequence is interruptible the following rules apply: If the element is absent this means there is no explicit pause duration restriction for the current slot; a value of 0s denoted the slot does not permit being paused.
Remaining pause time
If state is set to 'running' or 'paused' AND the slot is determined, this element SHALL contain the time the slot still needs to be in 'running' state (this also means the value remains constant during a 'paused' state). Otherwise it SHALL be omitted.

Resume energy estimated
The single steps of a power sequence are represented by slots. A slot is associated with a slot number (while a power sequence is associated with a power sequence identifier). The slot numbers of two power sequences should be considered independent from each other, i.e., slot number 7 of sequence 1 describes a different slot than slot number 7 of sequence 2. Therefore a slot is only uniquely identified in combination with a sequence ID.
