I have a cove where my shades will go, and in that cove they put an electrical outlet for wiring the shades. They didn't take into account that Lutron motors have to be wired with low-voltage. I'm planning on using a motor like the Sivoia QS D175. What would be the easiest way for me connect it. Can I just us a transformer or power supply hidden in the cove? I'm trying to avoid going into the drywall or redoing any wiring.
