Hello to everyone, today I am going to show you a project that I’ve been working on for a while, it consist on an ESP32 based Smart Energy Monitor that takes current and voltage samples through sensors in our power grid and shares the data to a local server made with Home Assistant and Raspberry Pi.

The electronics discrete components as resistors and transistors will be attached in a BOM file in the PCB Step.
