# The custom outputs are designed to work with Home Assistants energy system inputs..
# You will definitely want to rename the sensors + customize the shunt values but this gives you an idea..
# My voltage comes from the 2:1 voltage divider so the power outputs get multiplied by 2 as well and are
# scaled to kW as I prefer that to Watts for ease of reading at these power levesl
