I doubt metal box makes much difference when used with NMC (Romex). There is plenty of RF leakage on a metal box given the gaps. In any event the antenna tends to be oriented for radiation out the front plate anyway.

I live in IL where conduit for residential is code. I don't have any rf limitations with zwave.

I know you can get away with it most times but I only raised it just in case. I do know of occasions where it is the straw that broke he camels back and communication was lost.
I have one location with a metal box where it does communicate with Vera okay but I have lost an association link with another device. It works hanging  out of the box but not screwed in.

While it's great that you have not experienced any issues, others should not be misguided that metal boxes do not have an impact. Metal boxes definitely affect the Z-Wave signal.
