  ### [forceRead()](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/ElectricalPowerMeasurementTrait#/s:15GoogleHomeTypes6MatterO31ElectricalPowerMeasurementTraitV9forceReadyyYaKF)


  ` This API provides the ability to invalidate state retrieved through subscriptions to the
  target device in the cases where state is not being reported correctly, either intentionally
  (e.g attributes in Matter traits with the "C" quality) or unintentionally due to poor
  implementations.

  When successful, this API will result in a forced read of the convening scope as specified by
  the sub-class and return the result through existing Trait subscriptions if present and
  active.

  This API is to be used sparingly as it can impact the performance and battery life of the
  target device. As such, this API may be throttled by the platform.
  Callers SHALL be prepared to deal with `HomeError`s thrown by this call.

  #### Declaration

  Swift

      func forceRead() async throws

  ### [==(_:_:)](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/ElectricalPowerMeasurementTrait#/s:15GoogleHomeTypes6MatterO31ElectricalPowerMeasurementTraitV2eeoiySbAE_AEtFZ)


  ` Returns a Boolean value indicating whether two values are equal.

  Equality is the inverse of inequality. For any values `a` and `b`,
  `a == b` implies that `a != b` is `false`.

  #### Declaration

  Swift

      static func == (lhs: https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter.html.ElectricalPowerMeasurementTrait, rhs: https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter.html.ElectricalPowerMeasurementTrait) -> Bool

  #### Parameters

  |---|---|
  | ` lhs ` | A value to compare. |
  | ` rhs ` | Another value to compare. |

  ### [hash(into:)](https://developers.home.google.com/reference/swift/GoogleHomeTypes/Enums/Matter/ElectricalPowerMeasurementTrait#/s:15GoogleHomeTypes6MatterO31ElectricalPowerMeasurementTraitV4hash4intoys6HasherVz_tF)


  ` Hashes the essential components of this value by feeding them into the
  given hasher.

  Implement this method to conform to the `Hashable` protocol. The
  components used for hashing must be the same as the components compared
  in your type's `==` operator implementation. Call `hasher.combine(_:)`
  with each of these components.
  Important

  In your implementation of `hash(into:)`,
  don't call `finalize()` on the `hasher` instance provided,
  or replace it with a different instance.
  Doing so may become a compile-time error in the future.

  #### Declaration

  Swift

      func hash(into hasher: inout Hasher)
