I have tried this,?a long?time ago, with both CG-DMX and Enttec ODE for theaters.
I was to allow the control of DALI Lights from the Light Console.
I was working but at that time the Crestron Os (2-Series, 3-Series) was not designed to support a lot of changes.
It could work with a small number of circuits on the DMX and you have to limit the sending rate from the DMX side. Elsewhere, the Crestron processor will be stucked.
