Automation lamps A16_V3+E16_V2 with traditional switch

[ArlokBR]

Hello,
After watching some videos on YouTube, I started my home lighting automation project.

Using the A16_V3 + E16_V2 hardware and KCS v3.15.0 software.

I'm using a traditional doorbell switch as input and I'm having trouble getting it to work.
   
I made the connection between A16_V3 and E16 as follows:
I suspect my problem is that I'm connecting to digital input 1 + GRD.
Where am I going wrong? How do I use it with a traditional switch?

download KCS v3 for A16v3. connect your switch panel wire to A16v3's digital input port.
set by IFTTT:
IF DI1 = True THEN DO1=  toggle
IF DI1 = False THEN DO1=  toggle

I managed to solve the problem. I watched the YouTube videos, which are quite up-to-date; I was looking for older videos and didn't notice this change.
For anyone having the same problem, watch the video below; it's very intuitive.

What type of wire cable do you recommend buying? I think CAT cable has "too many wires" and I would be filling the conduit with wires that I might not use.
What 2-wire cables do you recommend? I found shielded 2x26 AWG cable for sale in my country (the wire gauge is approximately 0.13mm2).
Will there be any kind of delay when using it within 500 meters?

you can use any cable for digital input, no delay.
