OK, solved one problem and found another. Apparently, the Wii U only powers on the sensor bar if a Wii Remote is synced to the system. This is why it wasn't working when I had the remote synced to my PC :facepalm: The Wii always turns on the sensor bar so that's what I'm using now.
Now I just gotta fix the bluetooth connection issue. Apparently Bluesoleil is utter crap and decided it doesn't want to work anymore :/
