Just add one more as a jumper/pigtail to the box's ground screw. Since the box is grounded through the conduit (which is as good a ground conductor as any), you don't even have to terminate the ground wire to the box as long as the Z-wave switch has a metal yoke that contacts the box, although you can get a grounding screw (any 10-32 machine screw will do in a pinch), screw it into the back of the box (there . Especially if you are using the metal junction box as a self-made "extension cord" because if that box comes into contact with moisture getting an electric shock is a high probability.
