Hi,
Seems like LSC (Action) released a new version of the 5m LED strip, model number 3203632.2. It is still based on bk7231n, and flashing is quite easy.
Pins that are already described here:
https://community.home-assistant.io/t/using-l...1-rgbic-cctic-ledstrip-with-esphome/812822/35

But it has only 3 connectors; however, I can't use CW, W leds here, my config:

and Autoexec.bat:

Does somebody else have the same LED stip and could share with me autoexec.bat?

AI: Could you specify the exact board version or any markings on the PCB? This might help others with the same hardware share a compatible autoexec.bat.

I've got the same device recently from Action.
Button is pin 20:

Code: JSON
Log in, to see the code

The 5 m strip is divided into 25 segments, each segment containing two SM16703P controllers.
First controller per segment is driving the RGB LED; second controller drives one CW and one WW LED.

Therefore, the Init command should be:

Code: text Expand Select all Copy to clipboard
SM16703P_Init 50 RBG

By activating only the even controller of the strip, you can control the white LEDs.
Code: text Expand Select all Copy to clipboard
SM16703P_SetPixel 2 0 255 0 SM16703P_SetPixel 4 0 255 0 [..]
