Hi

I'm wondering what the purpose of Zone is in the Lutron data model. It appears to have a 1 to 1 relationship with the devices, eg only one dimmer per Zone. The only functional purpose I have found is for associating an occupancy sensor with a control device.

Is there an analog to a Group? For example, is there a way to create a Group of dimmers that I want to turn off together, in parallel, not sequentially, does Designer and RA3 support that?

Thank you
Peter
