I'll second Ry-dog's comments and add a few of my own that are particular to Leviton Vizia RF+ Dimmers. They are easy to integrate into teh Nevo Q50 as described above. When establishing the new network, it is critical that the Nevo Connect be the first item added and the Leviton RZCPG (remote programmer) is the last item added in the network. You do not necessarily need the RZCPG unless you are adding a Leviton Scene Controller into the network, in which case you also need to set the RZCPG to join the network as a SECONDARY controller.

After configuring everything, if you install an additional dimmer later on (as I did), the Q50 will recognize it, but the Scene Controller will not recognize it until you remove everything from the network and start over from scratch.

Nevo has a couple of good APP NOTES describing this procedure along with some videos on their website.
