Where does the yellow wire go

[mcf5757]

ecently got a smart motion sensing light switch for an office. It’s a 3-way switch (2 total switches). I am having a problem hooking it up.

Old switch has 2 reds/white/green wires

new switch has red/black/white/green/yellow wires

I tagged the one red wire as it seems to be the “common”.Not much luck gettting the right wires hooked up

Here are some pics of what I am dealing with. Also, the instructions that came with it that don't make sense to me either.

Any recommendations on how to hook it up?

Yellow seems to be a “signal” wire according to the instructions, which can be used in conjunction with another switch.

These are usually extra low voltage, and connecting them to mains voltage will damage something.

Run what is written on the red label
Through google translate, and see what it says.
