How do I wire a dead-end 3-way with Zooz Zen21 smart switch?

The following dead-end 3-way wiring diagram shows my current setup with the Zooz Zen21, but it's not working. This wiring works fine with a simple standard paddle 3-way switch that doesn't require a neutral wire. However, since the Zooz switch requires a neutral wire, I ran a white wire from the capped neutral wire from the breaker and the light switch to the neutral slot in the Zooz, but it didn't work. Is there another way to get the Zooz switch to work? Thank you in advance.

To simplify everything, I ignore the second switch in the garage and just use the Zooz switch to try to turn on the light switch. I have the following wiring and it's not working. I have tried the Zooz Zen72, Zen21, and the Kasa HS200 single pole switch. All of these smart switches that requires the neutral is unable to turn the light on with the following wiring diagram.

So, what's wrong with my wiring on the smart switches? Why are all of them not able to turn the light on?

I have also tried this wiring where the white wire from the light comes down to be capped with the neutral wire from the breaker and then a pigtail to the neutral slot in the smart switch as shown below in the wiring diagram. And this also didn't work.

Dont you need the traveler from motion swtch to whatever a zoosk is?

I dont see how the motion sensor has any input in any of your scenarios

I put the motion sensor there in case it affects the wiring of my smart 3-way switch issues and also to show the whole picture here. Yes, it shouldn't have anything to do with my smart 3-way switch but just in case it is because the motion sensor get its power from the same Romex cable as the smart 3-way switch.

Ill have to read up on a zoosk.

But your first diagram isnt correct.

Load is not a traveler. And vice versa

I have a similar product in my front foyer, i believe the upstairs switch just closes or opens.

Line and load happen at my downstairs switch.

It acts like a 3 way but isnt.

At this point, I'm trying to get this to work. Why is this not working on any of the smart switches? How do I re-wire so that it works because all smart switches requires a neutral wire.
