HTTP command

Hello everyone, I’m new here and this is my first project. I have an ESP8266 and a LED strip WS2814. I would like to send an HTTP command via a KNX visualization. When a KNX motion detector detects me, the light from LED 1 to LED72 should pass through and then be switched on. When you turn off the light, it should run back and then turn off. With Wled I always only see effects but not just a switch-on effect. Maybe someone can help me. I want to send the switch-on command and switch-off command via an HTTP command from KNX

use the preset on START up ((config LED)) to take your effect at start

I don’t understand, I’m new. Can you please explain it in more detail?
