Scene management was added to the zencontrol commissioning application in version 1.7.0
It can be accessed from the group summary page which can be reached through group management, or when viewing group membership for a specific device.
When on the group summary page, the scenes tab can be expanded to show the assigned scenes, as well as the ability to add a new scene. Clicking on an existing scene will allow you to edit it.
Adding or editing a scene will allow you to set a scene label, scene number, and set the scene level for each device. Moving the scene level slider all the way to the right will set a special value 255 which represent 'Do nothing'. The actual device level will track the scene level slider as it is being moved. Clicking on the device picture will send an identification command to the device. Click the save button in the bottom right hand corner of the screen once you are satisfied with your changes.
