I just purchased a Wemo dimmer for my fireplace room and have run into trouble wiring it.
My previous dimmer was wired:
When I wire the WEMO Dimmer in similar fashion (Red to Red) I get nothing.
Here are my test cases.
Any thoughts on how to get this to work?

Just tested the wall with a volt meter I have:
Black = Neutral
White = Nothing
Red = Hot
Green = Ground
Previous home improvers is my guess
Can I install it?:

It could be "power through fixture" style wiring (which is still to code), if so it won't work there. Also double check that it's not a three way switch as that is another reason it might have a red. If it was messed up wiring then probably test 6 would have worked. You might want to double check the wiring in the fixture to confirm it's what you expect.

If you have red, white and black connections to a non-wemo switch, then you have a multi-way switch. Red is called a runner. The runner allows any switch in the group to turn a light on or off.
While Red may be hot, it is not the same as a black wire (power or line in), and the two should not be crossed.
A Wemo Dimmer will not work properly with a three-way switch.
(or at least I haven't figured out how to get it to work)
