struct VolumeTrait
This trait provides a volume extension to the LevelControl
trait and is only for use with the
Automation API.

Creates a new Trait instance using data read from the given
TraitDecoder
.Throws
HomeError.parseError
when parsing fails.Declaration
Swift
init(decoder: TraitDecoder, interactionProxy: (any InteractionProxy)?, metadata: TraitMetadata) throws
Parameters
decoder
The raw data representing this Trait.
interactionProxy
Proxy to the Interaction Client.

-
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

Attributes for the
VolumeTrait
.Declaration
Swift
struct Attributes
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
a
andb
,a == b
implies thata != b
isfalse
.Parameters
lhs
A value to compare.
rhs
Another value to compare.
-
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. Callhasher.combine(_:)
with each of these components.Important
In your implementation of
hash(into:)
, don’t callfinalize()
on thehasher
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)
-
Whether the device supports the
moveToVolume
command for this trait.Declaration
Swift
var supportsMoveToVolumeCommand: Bool { get }
-
Move the volume of the device to the specified volume.
Declaration
Swift
func moveToVolume(volumePercent: UInt8) async throws
Parameters
volumePercent
The desired volume percentage setting in the range of 0 to 100.
-

-
Whether the device supports the
volumeStep
command for this trait.Declaration
Swift
var supportsVolumeStepCommand: Bool { get }
-
Incremental step volume. If volume + step is greater than 100, the volume is set to 100. If volume + step is less than 0, the volume is set to 0.
Declaration
Swift
func volumeStep(stepMode: Google.VolumeTrait.VolumeStepModeEnum, step: UInt8) async throws
Parameters
stepMode
Indicates whether to increase or decrease the volume.
step
Indicates the increment by which to increase or decrease the volume. Valid values are between 0 and 100.
-
The batchable version of volumeStep command above.
