I have two Commander Pros in my system. One that connects my AIO and PSU, the other runs the fans. Commander 1 connects the AIO and PSU shows up in the Sensors page, but Commander 2 with the fans does not. Both can be found in USB Devices page, and found in iCue.
I have attached an image of a basic map of how I have things setup.
Is there something I need to do to have both Commander Pros show up in Sensors?
