First led is addressable 5v RGBW that contains 1750 leds and x3 power supply 200w each.
Connections exactly like on picture:
First led works well till I add another esp32 to control second led (dummy) by PWM.
Second led is 24v 8 meters 7.2 A x2 power supply 150w each.
Connections are the same as on picture, except esp32 powered from dedicated power source Hi-Link 5v (gnd connected to 24v)
Once I start dimming second led, first led start flickering. Flickering started from ~600 led, first 600 leds works well.
power supplies 5v and 24v are located in one place. Wiring placed also mostly together (can change it).
Any ideas how to fix it.
