RGBW2 Wiring: licensed Electricians can't seem to figure it out... can anyone give some tips?

This is their current attempt (pun intended). They studied the Shelly wiring diagram for sooo long yet….

(I tried to embed the image but anyway here’s a link)

Anyway, this next pic shows the wiring diagram for the photo l posted.

The power is 220V AC. The thingy is the little strip that came in the box. The LED strip is only white colour.

At the moment, the wall switch now no longer works, the LED strip it does not turn on or off, but the Shelly has a green light. Am I supposed to use an app? I assumed I can still use the wall switch the same way.

In terms of wiring, is there something they/l am missing? Any guidance would be sooooo crazy appreciated.

Yes they did leave pins RGB open… as in my second wiring diagram that did not embed

I cannot see any major difference to the wiring diagram you posted unless I’m missing something.

Only that the “sig” is a 01-10V signal transformer.

This is what it looks like

Okay so what I want to say is it’s not working.

- The AC wall switch cannot not turn the LED on or off anymore.

- The Shelly module blinks green.

What is wrong?

Do I need to use WiFi to setup the module first, or will the AC wall switch continue to work as normal without any setup?

Because right now my wall switch is not turning on or off my LED strip anymore when I have the module attached according to the wiring diagram I sent. I thought the AC wall switch would continue to function as a regular wall switch.
