epsolar error "Platform not found: 'sensor.epsolar'"

The problem

Hi, I just found your code to add eppsolar mppt cahrge controller to esphome, tahnks a lot for your work. I'm trying to impement your code via esphome in my home assistant server, bit always get the aboce error. I know this is due to missing header files, but I have no clue how to include them and there's nothing about this in your documentation. Can you give me a hint or add information about this to the docs? Thanks a lot and best regards, Oliver
