Can I ask for a lead on the measuring probes-grippers from the project? Everything I can find at an acceptable price does not encourage me to plug into a live circuit.

on intermittent loss of WIFI connection. Then I will try to divide the tasks into two processor cores. For one to handle WIFI and the other to read measurements and calculate them.

Something is different because ARDUINO IDE uploads from 0x0000
It's a description
I am replying to the last 3 posts in turn.
As for the sensors for measuring the current, they are available at a price of about PLN 27, they have become a bit more expensive. Because I checked and there is a lot in a different measurement range on a well-known auction site.
