Ah, sure.
Well, the hardware is a bit tricky. I’ve had a manufacturer, that makes LED based lighting products make a number of 360deg LED tubes. They have slid two LED strips back-to-back into a diffusing silicon tube and enclosed it in a hard acrylic tube. It’s quite nice. Trouble is, this company isn’t used to dealing with adressable LEDs - they’re more of a DMX company. So when i required addressable LEDs, they just asked their supplier for addressable LEDS, and I ended up with the mess that is WS2814a. At least, that’s what they tell me.
I can’t verify for sure, as the actual strips are enclosed in a tube.
The tube as a cord in one end with 5 wires - red and white are soldered together as is blue and green while black is single. They tell me red/white is 12v+, blue/green is GND and black is data.
So on a 2.5m tube, I have wired red/white and blue/green to a 320w 12v psu. Blue/green is also connected to GND on a Wemos d1 mini, and black is connected to GPIO2.
With wled, I have tried all configurations I could think of, inspired by Incorrect channel order for WS2814A RGBW strip. · Issue #2646 · Aircoookie/WLED · GitHub
I have tried the TM1814 protocol, as it seems similar to WS2814a.
I have tried a “standard” neopixel sketch (having previously used that for other RGBW strips) as well as this FastLED aproach: FastLED with RGBW NeoPixels (SK6812) - Parts Not Included
I’m getting nothing, that makes any sense 
With wled and the wiring described above, almost nothing happens. Sometimes a single LED lights up in a orange-ish color at the end opposite the wires.
However, if i reverse the wiring toward the Wemos (ie. attach ground to DATA), it get a little more - sometimes 5 ot 10 leds light up. Sometimes white, sometimes various colours. But they stay the same color if I enable effects.
When I unplug the 12V power, they do flicker a bit (sometimes even resembling an animation), but once I plug it back in, it goes into another “static” frame.
I’m awaiting further information from the manufacturer, but my experience with them has not been great, so I’m digging around until further notice.
I’m not all that experienced with LED strips, but I have done my fair share of stuff with WS2811/2, and that has always been smooth sailing. This … this is not
