Appreciate the response pclin.
Yes, setting colors works from web view and mobile app.
No LevelShifter installed, couldn't find where buy one. Debug log had no issues once I fixed the root permissions.
Ended up just buying SK6812 and switched to SPI and everything working as it previously was. Guess i'll hang onto the WS2815 strips and save for another project if i can find an appropriate LevelShifter.
Searched and could not find a similar issue, so creating new thread.
I have a fully working config on RPi3 + WS2815 LEDs.
Specs:
LED - WS2815 ( https://www.amazon.com/gp/product/B07LG6J39V?tag=hyperioforum-21&ie=UTF8&th=1 )
PWM - GPIO18 (DI on the strip, have tried both DO and BO)
12v power source
Everything is configured and working correctly, however I cannot set the colors to be gradients or even white. I only see the primary colors (Red, Blue, Green). Im able to reduce brightness, but cannot set the color to white, yellow, orange etc.
This is a new LED strip as I was previously using WS2801 for many years with no issues, but wanted to upgrade to HyperBian (was using old Hyperion with the .jar to configure it).
Im about out of ideas, help!
