I want to measure the AC shore power current usage on my boat. It is a 120v 30amp cable. I have some experience using a Adafruit esp32 feather and their mqtt data logging service “IO”
I am looking for a recommendation on which board to purchase and hopefully be able to use it with the esp32 board, and if you have a link to any arduino code to read the sensor ? Ideally looking for a sample code that can do a serial.print on the current value and I should able to take it from there.
