WHAAT? I'm getting crazy.
I bought a ACS712ELCTR-05B-T (5A)-version which gives same results of 745 regardless of load . I used a 40W LED bulb on AC power, with Wemos D1 Mini (ESP8266). I tried my clamp meter, put it around the brown wire and got 0 reading.
My AC has only 2 wired: brown & blue, with interchangeable wall plug. Is the 231V AC, or this European double-wiring unsuited for the ACS712?
Do I have it wired incorrectly from mains --> sensor?
My Wiring is..
blue wire ==> 40W LED light
wallplug brown wire ==> ACS712 in ==> ACS712 out brown wire ==> 40W LED light.
