Control "ws2811" addressable rgb led strip with esp32

I have bought an addressable RGB Led Strip from banggood. It was titled as an ws2811 RGB Led Strip. But I only have found ws2811 RGB Leds which aren't Strip, but LEDs connected with some wire. I have some doubt that these are ws2811 LEDs. I think they are ws2812 LEDs titled as ws2811s. Now I try to control them with my ESP32 with the FastLED library but it does not want to work...

Here is my code:

#include <FastLED.h>
#define LED_PIN     27
#define LED_COUNT    1
CRGB leds[LED_COUNT];

void setup() {
  FastLED.addLeds<WS2812, LED_PIN, RGB>(leds, LED_COUNT);
}

void loop() {
  leds[0] = CRGB(255, 0, 0);
  FastLED.show();
}

Here is my wiring: My Wiring. Sorry for the catastrophic drawing...

My problem is that it does not want to work!

Has anyone an idea why? Thanks a lot!

The esp 32 if I'm correct outputs 3.3V signal. The minimum voltage for WS2811 signal input is 5V. So you will need to use transistor to step up the voltage. I tried it but it didn't work, perhaps i choose the wrong transistor but it was the only one i had available that is PNP. Also please respond if you find the solution. :)
