I really need some help with that plugin. I searched the forum and net already but I could not solve it.
I installed the plugin and set up my LED. Wiring was made like recommended in the wiki (Wiring your LEDs - WS281x LED Status). The following components are used:
Raspberry Pi 3B with OctoPrint 1.6.1
for level shifting I tried:
Because of only 8 LEDs in use I do not use an external power supply but drain power from my Raspi.
The Open OS config Test passed without errors.
Nevertheless I don't get control over my LEDs via the plugin.
Without the level shifter the buttons for the LED strip test (red/green/blue/white) sometimes work and sometimes don't. Other functions like visualizing the heating process don't work at all.
With level shifting the buttons for the LED strip test (red/green/blue/white) don't work at all. The strip does not change color. I can see only a slight shift of brightness... sometimes. Additionally the first LED in the row always shows a different behaviour than the others.
The log shows no errors.
I am really desperate! Any ideas?
