Hi everyone! (Using some account I got from bugmenot, hope you don't care not sending me an SD Card

Got a couple of these ceiling lamps a while back, had some trouble figuring out how to get the cool white working (but as I like warm white better, it was never an issue, until I moved in with my GF...). Now I've finally solved, thanks to some google-fu and trial and error with PINs.
These are Ledvance round ceiling lamps, I'm not sure if these models are sold anywhere outside Latin America. EAN is 4058075636347.
Wifi Module is WB2L, with a BK7231T chip.
They are announced as RGBW, but they truly seem to have cool and white LEDs inside. Instead of the more common design of 1 PWM for Warm white and 1 PWM for Cool white, they have a PWM controlling whether it's cool or warm, and another PWM for the brightness (as I found in https://www.elektroda.com/rtvforum/topic4026971.html#20897713).
The Pin configuration is as follows:
----- ------- --------- -------------------
| Pin | Role | Channel | Comment |
----- ------- --------- -------------------
| 6 | PWM | 0 | Red |
----- ------- --------- -------------------
| 7 | PWM_n | 3 | White Temperature |
----- ------- --------- -------------------
| 8 | PWM | 4 | White Warmness |
----- ------- --------- -------------------
| 24 | PWM | 2 | Blue |
----- ------- --------- -------------------
| 26 | PWM | 1 | Green |
----- ------- --------- -------------------
And you'll need to set the flag 8: [LED] Alternate CW light mode (first PWM for warm/cold slider, second for brightness)

AI: Hey, just to clarify—are you looking for any specific help or feedback regarding the pinout and PWM configuration you posted, or were you just sharing your findings for others?
Sharing my findings
AI: Is there any particular issue or question you still have about getting the lamp fully working (like with the cool white, warm white, or RGB channels), or is everything sorted now?
Everything seems to be sorted out now!
