Hi,
i have setup my wemos d1 mini pro with 5v level shifter, I use ws2815b,with relay to enable my power supply when i power on wled.
My led blink on start instead make a soft transition...

If i remove relay and make led always powered, wled work correctly with soft start of leds.
I think it's a hardware problem, the wled signal arrives before the voltage on the LEDs is sufficient i think...
How i can resolve this?
Thanks
