[Problem} Selection of Tuya Zigbee modules for 1 gang 2 way 86x86 switches - how to connect?

Hi everyone.

For the house I am currently building, I will be looking to install light and roller shutter switches bought on AliExpress. The kind under an 86x86 square box.
For this, I wanted to buy simple Tuya modules that I will hook up to a Zigbee gateway.

And this is where the problems begin. I don't know how to hook it up, which modules to choose.

1) The switches I want to buy are 1 gang, 2 way. It sounds weird because it's like it's supposed to be a staircase switch, but they're all like that on AliExpress, no 1 way. I attach a photo.
2) The module itself. I have a choice of 1 to 4 way, I was just looking at the dimmer version, but the wiring layout looks the same. I attach a photo.

I'm not familiar with it and don't know how to wire it up. According to the picture, a simple matter:
L and N from the switchboard.
L1 and N to the bulb (the neutral wire from the distribution board goes to both the module and the bulb, right?)
S1 to the switch.

And this is where I seem to have a conundrum. It appears that only one wire goes to the switch? How is this supposed to work?


[Edit] I've added a drawing of how I see it. I don't know how correct this is. Especially if the light switch has an output for 3 cables, from what I saw in the auction pictures. Is it enough for me to connect under two?


I know this is probably obvious to many, but unfortunately for me. I would therefore be very grateful for any info;)

You have it all well drawn, and the cable to the switch may go one but there must be and are two wires.... When the switch is a two-way switch and has three contacts it can still be used in a normal non-switched circuit as it has two positions of which one connects two contacts and in the next position it disconnects the same contacts, simply, even if you don't understand it, you will connect two contacts in the switch, choosing those on which the circuit will work properly e.g. by trial and error... And if you want the circuit to be connected upwards and disconnected downwards, if it doesn't suit you, turn the whole switch by 180 degrees and it will be OK...
I only have a request that you use the term "wire" when it is a single wire and the term "cable" when it is a set of at least two wires and more and your vocabulary will be correct and in future every electrician will understand it as every other electrician should...

Yes, you only need to connect under the right two and "clockwise" you have three possibilities with three contacts and if the first attempt fails then the second attempt will be the right one no matter if left or right you will put one of the wires or both at once....

Well, yes, when you have stairs you have to buy staircases and how many you have to know the building plan and possibly also the electrics because we don't know how many floors up and how many down etc. etc.. And stair lights are used not only for stairs, but also in long corridors or in two entrances to one and the same room in order to be able to light a lamp or lamps on both sides of the room and if one lamp is a single path, and if two lamps are switched, it is a double path and that is why the names (way) are introduced - paths or circuits....
