Hello everyone,
I have bought a WS2812B Led stripe (160 leds/meter). I attached an image with the technical data. When I connect to Athom it starts flickering (I attached a video); also the green light of the power source blinks (when the led stripe it's not connected doesn't blink: I also attached a video).
I also attached 2 screenshots of the settings that I have in WLED:
You used the wrong power supply, your light strip is 5V, and you used a 24V power supply, so your light strip has burned out
