Smart Home Light Effects Trait Schema

action.devices.traits.LightEffects - This trait belongs to devices that can natively support complex lighting effects, such as looping through various colors.

Device ATTRIBUTES

Attribute Definition
defaultSleepDuration Integer. Optional. The default duration in seconds for the effect triggered by the action.devices.commands.Sleep command. Defaults to 1,800 seconds (30 minutes).
defaultWakeDuration Integer. Optional. The default duration in seconds for the effect triggered by the action.devices.commands.Wake command. Defaults to 1,800 seconds (30 minutes).
supportedEffects List of strings. Required. List of the effects that the device will support. Valid effects for the device include:
  • colorLoop: Loops through various colors randomly.
  • sleep: Gradually lowers brightness and, optionally, adjusts the color temperature over a period of time.
  • wake: Gradually increases brightness and, optionally, adjusts the color temperature over a period of time.

Device COMMANDS

Command Parameters/Definition
action.devices.commands.ColorLoop Request the device to cycle through a set of colors.
action.devices.commands.Sleep Gradually lower the device's brightness and, optionally, adjusts the color temperature over a duration of time. This command takes the following parameter:
  • duration: Integer. Optional. Represents the duration for the sleep command in seconds.

Alternatively, see the action.devices.commands.Wake command.
action.devices.commands.StopEffect Stop the current light effect.
action.devices.commands.Wake Gradually increase the device's brightness and, optionally, adjusts the color temperature over a duration of time. This command takes the following parameter:
  • duration: Integer. Optional. Represents the duration for the wake command in seconds.

Alternatively, see the action.devices.commands.Sleep command.
