ESP32 + WLED, LEDs turn on when ESP32 is plugged in power. How to prevent this from happening?

[lorossi]

I have a set up with 20 WS2812B LEDs and a ESP32 with WLED. I am not connecting a power supply to the system, I'm powering the LEDs via the ESP32 board. My problem is that every time I connect the ESP32 to my energy source, all of the LEDs turn on until I connect via the app and turn them off. I would like the LEDs to not turn on automatically when connected to the power source. Is there a way I can change that? Thanks in advance.

Hello,

since you are using a third-party software, I don't think we can help you here, I am sorry.
Please ask directly WLED community about this issue.
This is a link to their Discord channel I found on their website: https://discord.com/invite/KuqP7NE

20 WS2812B LEDs ...powering the LEDs via the ESP32 board

Those LEDs can draw about 60mA each. Not sure if your board (and 5V supply) can handle 1.2A in addition to the 0.3-0.5A the ESP requires, or, worst case, a 1.2A ripple at some 400-50000Hz.

In WLED settings web page choose "Solid" for the effect mode. Then for color choose black.
Then go to presets and save that setting as the preset. On boot it will run that preset, and keep them off
