Hi,
I am back from vacation.
I will contact you via WhatsApp.

Just to recall:
  1. I have YMDC SCT013 20A/1V class: 1(and 50A/1v).
  2. I do not have problem with mini-jack plugs. I connect SCT's jack into the plug and then into the appropriate terminals of N30. I checked the connections and all works fine. This is not the problem. 
  3. I tested the SCT on the wire of an electric kettle.
    I measured the current: 8.2A (voltage is 230V), but no readout in the logs of ESP32-generated firmware though. I measure the voltage on the terminals of N30. It swayed way beyond 1V.

Looking for help.

Stan
