FEIT Wifi Smart Dimmer Switch Install - Help Needed

Hello,

We are wanting to replace a broken dumb dimmer switch with a FEIT wifi smart dimmer switch in a 3-pole setup. We are a bit confused on how to wire it up.

We will attach images and hope that will help.

We plan to keep the one standard light switch at one end of the hall and install the smart dimmer at the other end of the hall to control two light sconces.

Any help in making sense of this install will be greatly appreciated!

Wiring diagram for electrical box where we want to install the smart dimmer. We wired the smart dimmer up (notes on how we wired it are included in the diagram). The switch powers up and can be turned on / off from the other light switch, but the light fixtures do not turn on / off.

How the previous "dumb" dimmer was wired.

Diagram of the single light switch at other end of the hall.

Product model number.

Feit's installation instructions.

In order for it to make sense we must see all the connections clearly.
Your diagrams don't look correct.

I see a two wire and a three wire cable in the first box but can't see all the splices.
You said you're using the black wire on the left to dimmer AC-L. That means that black wire is hot. If that is correct.... the white should be the dimmer neutral.

I see another two and three wire cable in the second box. Can't see the colors in that splice.
Looks like a white wire is missing.
Your diagram shows red, white and black connected. That's not right.

Hi Pete,

Thank you for your response!

We updated the diagram of the single light switch and added an image of it from another perspective...hopefully that makes it more clear.

The red, black and white wires weren't actually connected together as indicated in our first diagram...they are connected to the light switch terminals. Our apology for the confusion.

You are correct. It does look like a white wire is missing on the right side of the box...it's just a black and ground wire coming out of that cable. There is a light switch in the bedroom on the other side of that hall wall...maybe that has something to do with the missing white wire?

Regarding the dimmer switch box: We see the same thing that you are seeing...a two wire and three wire cable. We do have the black wire on the left to the dimmer AC-L (as that appeared to be how it was wired on the previous dimmer switch). You wrote that the white should be the dimmer neutral. That's how we currently have it set up...the white wire on the right is connected to the dimmer neutral.

The white wire from the left cable is spliced to the black wire from the right cable via a wire nut.

I'll see if I can get a better picture of the connections in that dimmer switch box.

Additional photos

Pete, here are a few more pictures of the hallway dimmer switch box and wiring.

The wiring diagram for this box appears to be correct.

We have power to the dimmer switch, but no power to the light fixtures (there are two sconces in the hallway)...

Any ideas where we are going wrong?

Pete, we had one thing wrong on our description of the dimmer switch electrical box...

The white wire from the LEFT cable is spliced to the black wire on the RIGHT cable.

The diagram was correct, but our description was wrong previously. Sorry for the mistake.

We tried wiring the black wire on the left to AC-L and the red wire on the right to LOAD on the smart dimmer switch. The light would turn on momentarily and then shut off right away.

At this point, we're not sure what other configuration would be correct and have capped all wires and tucked them back into the electrical box until we can figure this up.

We are wondering if the white and black wires that are tied together need to be connected to the switch in some way.

Updated pictures of the electrical box wiring attached.
