I've tried wiring My HS220 in a single pole set up replacing another smart dimmer, I've wired it correctly  because the original dimmer is configured the same as the HS220, but get no power on the HS220. If I put the load wires and terminate on the line terminal the switch powers up. I tried putting the line feed on the load terminal with the switch but obviously the light won't come on. Has anyone experienced the line and load terminals being reversed out of the box?
