In this project I will show you how to build an ESP32 AC power meter that can be used with your home assistant setup. That means I will firstly explain how to actually measure and calculate real and apparent power along with the power factor and then I will show you how to use the ESP32 in combination with some complementary components in order to create the power meter. Let's get started!
