Hi:
i has a trouble about GlobalSceneControl Attribute in on/off cluster.I don't know what is the meaning of this attribute .
And i didn't know the meaning of those red marks.
The global scene is defined as the scene that is stored with group identifier 0 and scene identifier 0.
The GlobalSceneControl attribute is defined in order to prevent a second off command storing the all-devices-off
situation as a global scene, and to prevent a second on command destroying the current settings by going back to the
global scene.
Here is the chart about this process.
