The scheduled activation delay for a slot.

The duration description for the activation delay duration temporal entity

The duration description for the active duration (min and max, sum max and sum min) temporal entities

The active maximum duration a power sequence can run without interruption.

The active mininum duration a power sequence can run without interruption.

The active maximum duration a power sequence can run in total (summation of all active times).

The active minimum duration a power sequence must run in total (summation of all active times).

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.

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 collection of power sequences for a certain profile

The duration description for the anticipation duration temporal entities

The duration of a slot (SHALL be present in case of 'determined slot'). If a slot has a configurable lenght, this element SHALL reflect the currently configured lenght

The duration description for the default duration temporal entity

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 uncertainty of the duration

The duration description for the duration uncertainty temporal entity

The earliest possible start time for a power sequence or a slot. Only 'xs:duration' value types SHALL be used to denote a relative time which relates to 'now' as time 0.

Note: This element applies to the first repetition of the slot number only.

If state is set to 'running' or 'paused' AND the slot is determined, this element CAN contain the time the slot has already been in 'running' state (this also means the value remains constant during a 'paused' state). Otherwise it SHALL be omitted.

The endTime of a power sequence. If the value is available, it SHALL be denoted here. Otherwise the element SHALL be omitted.

The end time of a slot MAY be stated in this element. The following equation SHALL apply: endTime - startTime = defaultDuration.

A possible type of power in a slot that represents the maximum power consumption and its value

A way to model curves of power and energy over time, which also provides definitions for the modelling of power scheduling including alternative plans. With a PowerProfile, a device (or power sequences server) exposes the power sequences that are potentially relevant for the CEM (or power sequences client).

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.

The current state of the power sequence. It can assume one of the values 'running', 'paused', 'scheduled', 'scheduled paused', 'pending', 'inactive', 'completed', or 'invalid'.

A possible type of power in a slot that represents the power skewness and its value

A possible type of power in a slot that represents the power standard deviation and its value

The duration that the current slot (s4ee:activeSlotNumber) permits being paused. This element SHALL ONLY be present if the power sequence is interruptible. 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.

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.

In a power sequence the additional costs for the resumption of a device to its normal operation (after a pause).

In a power sequence, the additional energy the device will consume before resuming its normal operation (after a pause). This is only an estimated value which will not be added to the value stated in any slot value information.

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.
