Help with a 3 way

I have a single gang box with 3 romex coming to the box.

There are 2 light fixtures in the 3 way. I am using a White Series 2-1 Switch VTM31-SN-IV a GE addon switch. I have a 5 way using a White Series 2-1 Switch and 3 GE addon switches and 8 light fixtures on it and it works just fine. I have this on wired like the following. The box where the power is coming in.


and the 3 way at the other end like this.

The White Series 2-1 Switch is configure as on-off aux. My problem is the lights ficker. I cannot figure out why they flicker when I have it wired just like another 5 way I have any idea’s?

I can’t see into your primary box well enough, but here are a couple thoughts/questions:

Looking at your diagram, it looks to me as if the hot originates at the 2-wire lower left. Please confirm this by testing with the black disconnected from the other conductors.

It looks as if the 3-wire, lower right, is going to the other switch. At the other switch with the single 3-wire, was the black connected to the black screw on the dumb switch?

The 3-wire at the top looks to be going to the light(s). Black is the switched hot and red is a constant hot for something downstream.

This is solely based upon looking at your drawing.

Looking at the picture of your Inovelli, if I am correct, this is a neutral installation. So I would expect the black from the 2-wire lower left in the Line terminal and a white from the white neutral bundle in the Neutral terminal. But there is nothing in the Neutral terminal and there is a black AND white in the Line terminal. I can’t see where they are going, but this can’t be correct.

I’m guessing, without seeing into the box, that you are sending a hot to the Aux switch? But this should be wired as a neutral installation with the Aux getting a neutral (as well as the Inovelli).

EDIT: I see you tagged this as a non-neutral, but I think should be a neutral config.

Here is how the box is wired.

Ok, thx . . rethinking . .

You tested with the black from the 3-wire top right disconnected from the switch?

If that’s where the hot is coming from, I just can’t envision the rest of it. That would mean the hot is being sent to the other switch via the red and white travelers, bottom right. That means it’s returned over the black of the 3-wire, bottom right, which is connected in a bundle to the red, 3-wire top and the black of the 2-wire left, bottom. I might be missing it, but that makes absolutely no sense to me.

Maybe someone else can see it. But please double-check to make sure the black you identified is really the incoming hot. If you have a meter, test between that black and the white to see if you get 120V

I have checked it and the power is coming from the black wire of the 3-wire top right. I have all the wires disconnected and that is where the power is coming from.

This is how the 3-way was wired orignially. I just left the wire nut off the black wires

This is still not making any sense to me.

You’re advising that the hot is coming from the top right 3-wire black, but if you look at how you wired the Inovelli, you have that conductor wired to the Load terminal. So if that’s really the hot, why is it on the load terminal?

Everything I’m seeing is consistent with my first drawing. The way you have the switch wired now is very close to what I drew out. You have the Line connected to the black/red bundle and you have the Load connected to what I think is the load conductor. But you’re saying that’s the hot.

And in looking at the picture with the dumb switch, I see the black/red bundle is connected to the black of the 3-wire going to the other switch. This is a conventional dumb 3-wire configuration, with the hot being sent to the other switch first, which also suggests that bundle is the hot.

But you believe the hot is coming in from the top right, so if that is the case, then my diagram is not correct. I have looked to try to understand how that can be the hot and work given all of the other wiring, and I don’t see anything that makes any sense to me.

So unfortunately, I have nothing else to suggest.

I have an electrician coming today to help me sort it out. I will let you know what I figure out.
