ConstReadonlyattributes: { ReadonlyneutralThis shall indicate the most recent NeutralCurrent reading in milliamps (mA). Typically this is a derived value, taking the magnitude of the vector sum of phase currents.
If the neutral current cannot be measured or derived, a value of null shall be returned.
A positive value represents an imbalance between the phase currents when power is imported. A negative value represents an imbalance between the phase currents when power is exported.
The reporting interval of this attribute shall be manufacturer dependent. The server may choose to omit publication of deltas considered not meaningful.
The server shall NOT mark this attribute ready for report if the last time this was done was more recently than 1 second ago.
The server may delay marking this attribute ready for report for longer periods if needed, however the server shall NOT delay marking this attribute as ready for report for longer than 60 seconds.
A ElectricalPowerMeasurementCluster supports these elements if it supports feature PolyphasePower.
