Do you have a web address for Energy Savings? I could not find it this afternoon. They might have some details on the protocol & command set. I have found that DSI & DALI use manchester encoding but not what the physical interface is yet. I will contact ATCO tomorrow to see if they will talk about it. If anyone else is interested I will post the results of what I find to the list.
