WEMO Hardware

[minfootball]

Hi all,

I just purchased a Wemo dimmer for my fireplace room and have run into trouble wiring it.

My previous dimmer was wired:

Wall       Dimmer

Black      Black

White      White

Red         Black

Green      Green

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?

	Wall	Green	White	Red	Black	Switch On	Lights On
Test 1	WEMO	Green	White	Red	Black	Fail
Test 2	WEMO	Green	White	Black	Red	Fail
Test 3	WEMO	Green	Red	Black	White	On	Fail
Test 4	WEMO	Green	Red	White	Black	On	Fail
Test 5	WEMO	Green	Black	Red	White	Fail
Test 6	WEMO	Green	Black	White	Red	Fail

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?:

Wall     Wemo Dimmer

Black    White

Red       Black & Red

Green    Green

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.

With regard to this matter, this link might be of help. However, we suggest that you contact your local electrician for further assistance.

Just checked it is a power through fixture style. Darn I really like the ease of use of this dimmer.

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)
