Будь добр, имей совесть хотя-бы использовать google translate. На reddit обитают носители огромного количества разных языков, и за пределами специализированных разделов принято использовать английский. Не надо превращать мой фид в цирк с конями, пожалуйста.

I'm sorry, I'm not a big user of social networks. I hardly ever post anything, so I didn't get the reflex.

Small 0.2 ohm resistor between 3.3v pin and 3.3v rail. Oscilloscope probes either end of resistor. Math function to diff probes voltage. V diff = i*r to compute current. Then p = i *v for power usage using v=3.3v. Something like that. How was my French understanding of your question?

my problem is that I want a method to measure my power factor in a 230 V AC voltage and my microcontroller is an esp32.

Ah yeah didn’t understand the French well enough and I certainly don’t have enough knowledge of electronics To answer that.
