Title: Troubleshooting WiFi Touch Switch Connection Issues in Kitchen & Toilet - 2-Way Switches

Hello
Can someone help me connect the WiFi touch switch? I already installed such switches and everything was OK now, but I wanted to connect in the kitchen, but here I "buried myself" because the kitchen light is turned on by two switches where I can turn on one and turn off the other. When I connect blue under N, brown under L1, the light starts blinking whether it is on or off, the reaction is the same, connecting yellow under N brown under L1 no reaction when I turn on the light with the second switch (manual), the voltage appears in blue.
I am already tired of this situation and I am asking for help
Thank you in advance and best regards

There is no mate in this box, neither "N" (ie neutral wire), nor "PE" (ie protective conductor).
You probably won't connect a WiFi dongle here.
Please include a schematic diagram of how this device should work.

For a socket in the bathroom, the insertion of wires in the connectors is incorrect.

Hello and thanks a lot, but I can see that it will not work. the best thing is that in the living room I was able to connect two lights with a double WiFi switch, and not here.
