I have a scene titled Auto DR.  It may be an artifact of some mistake that I made years ago, however, I have no idea of why it is on my ISY network list.  The scene contains no devices.

 

I have attempted to delete the scene and I get a simple error message which states "request failed". 

Is this scene mean anything and if not, how can I delete it?

That's a special Managed Scene and part of the ISY, you can't delete it. I've put it in a folder with extra or unused devices

Its related to the ISY's power management options and the ability to respond to a power companies "Demand Response" program... if they have one and if you have the ISY with ADR Zigbee board that can talk to your AMI smart power meter - if you have.  Devices in that scene can be configures to switch off when your power company has a demand spike and the cost goes up
