The change to be added to (or subtracted from) the current value of the device’s saturation.
The TransitionTime field specifies, in 1/10ths of a second, the time that shall be taken to perform the step. A step is a change in the device’s saturation of ‘Step size’ units.
NOTE
Here the TransitionTime data field is of data type uint8, where uint16 is more common for TransitionTime data fields in other clusters / commands.
