| Description | This object specifies how the usage value reported by
eoPower was obtained:
- unavailable(1): Indicates that the usage is not
available. In such a case, the eoPower value must be 0
For devices that can not measure or report power this
option can be used.
- unknown(2): Indicates that the way the usage was
determined is unknown. In some cases, entities report
aggregate power on behalf of another device. In such
cases it is not known whether the usage reported is
actual(2), estimated(3) or presumed (4).
- actual(3): Indicates that the reported usage was
measured by the entity through some hardware or direct
physical means. The usage data reported is not presumed
(4) or estimated (3) but the real apparent current energy
consumption rate.
- estimated(4): Indicates that the usage was not
determined by physical measurement. The value is a
derivation based upon the device type, state, and/or
current utilization using some algorithm or heuristic. It
is presumed that the entity's state and current
configuration were used to compute the value.
- presumed(5): Indicates that the usage was not
determined by physical measurement, algorithm or
derivation. The usage was reported based upon external
tables, specifications, and/or model information. For
example, a PC Model X draws 200W, while a PC Model Y
draws 210W |
