wLed staircase

Hello everyone, I am trying to make a lighting for a staircase of 20 steps. But I can’t figure out how to set up presets and segments. And I can’t even get the hc-sr04 sensors to work. someone can help me. The firmware with usermod I have already uploaded on esp32.

I have not found an answer. They don’t talk about segments or stairlights
