All you need for a modern fan with a remote is power, neutral and ground. Older fans needed neutral, ground and 2 power wires - 1 for fan, 1 to lights (black and red, usually).
If the fixture isn't controlled by two separate switched, this is my guess. It may have had a ceiling fan in the past. I would wire this way if I wanted the fan always powered (controlled by the pull chain) and the light switched separately. Alternately, -3 wire is used if you want to control two separate fixtures from a single switch. Are you sure both are hot or is the current sensor just picking up bleed over from the always on circuit? How are the red and black used at the current fixture, i.e., what is the red connected to?

I agree, you need to see the switch box to get the whole picture. If power comes to the fixture rather than the wall switch , a switch leg could be installed. You could do this with -2 wire and switch the white, but it should be marked with black tape.
