There has been a lot of discussion here recently about newer HA technologies (Insteon, ZigBee, Z-wave, etc) replacing X10.
Which, if any, of these newer technologies offer (or have the capability of offering) wall switch dimmers which don't require a neutral wire in the switch box?
Plug-in dimmers are fine, but I have many more (X10) wall switch dimmers installed in my house. As far as I can recall, none of the switch boxes have a neutral wire and it would be prohibitively expensive to have them rewired. And I suspect that the switch boxes in most houses don't have a neutral wire.
It seems to me that any HA technology which doesn't or can't offer wall switches that work without a neutral won't get very far, except possibly when pre-planned for in new construction.
