Update: The Legrand dimmer worked. Probably thanks to the neutral wire. However it was too large to fit in the electrical box!
So I am now on the hunt for the Lutron DVRP with neutral connection, which seems to be smaller, and the same size as the non-RP Diva.
It looks like it's back ordered everywhere... Can you provide an idea of when it will be restocked? OR are there other lutron dimmers that have a neutral wire?
