Installing Sonoff switch with different wiring?

[IvanSono]

Hello everyone. At home I change all wall switch with a sonoff t2. I didn't have a problem until I got to the bedroom. When I connected the light switch, and pressed the power button, the lamp turns on and off instantly. I came to the following problem. The wiring in the room is as follows:wiring
I know that wiring is wrong,and I wonder what can be done without making a significant change to the installation

That is the wiring in bedroom.

Is that diagram correct? I'm not familiar with Bulgarian methods, but in the UK we would have neutral connected to the lamp, and the live feed via the switch. We use 2 methods, one of which takes neutral to the switch point.

Do you use twin and earth cable?

Yes, here that is old style of wiring... In most of the old buildings, the installation is such as the diagram. In new buildings, the installation is exactly as you described it. In my case, everywhere the installation is neutral to the lamp, and to the switch is the phase, but in the bedroom things are not so. Now I found a wiring diagram that miss neutral in the switch box.

If I do something like this in my situation, will it work?
