The problem with those (and why I think no one makes anything like that anymore), is it means you have a low voltage wire coming into a box with line-voltage. Which is illegal per NEC code.
There used to be an exception to this rule as long as the low voltage conductors are 1) used to control the high voltage device, 2) they are rated to 600V and 3) are kept 6mm away from high voltage connections.
Not sure if this went away with new version of the code. Anyone who installs Lutron Homeworks Wired Maestros should know for sure.
