Hi,We're building a new build home, and are looking at RA2 select (Radio RA2 not available in the UK)Forgive the lack of technical knowledge, but what is the difference between the inline dimmer switch and the PowPack?My understanding is that the inline dimmer is placed close to the light fixture, for each individual circuitCan the Powpack control multiple circuits, but still allow for dimming of specific circuits to create scenes?Thanks,Raj
