    Here we go again.
    A few weeks ago I bought an LSC Smart Outdoor Party Light (3200490) that works with LSC or Tuya.
    It has 20 Bulbs, RGB/C + warm white.
    Colorful bulbs of the LSC Smart Outdoor Party Light set on packaging.
    Printed circuit board with connectors and electronic components inside a casing.

    Flashing was no Problem. But if I toggle on all LEDs have different colors. If I change to blue this is the result, one G, one R, one B and so on. That confuses me, normally all LED should have the same color.

    String lights with multicolored LED bulbs hanging above a cabinet.

    Every bulb has one small chip with WS2814A

    Electronic module with LED setup and markings. Circuit board with WS2814A chip and wires

    The string works with SM1670P driver for RGB but CW and WW won't work

    Code: JSON
    Log in, to see the code

    PixelAnim works, but the LEDs are mixed up and there is no clean rainbow effect.

    I'm sorry, but I forgot to make a dump :-(

    Somebody out there who has the same String and bring it fully to work?

    Hello, are WS2814A timings the same as WS2812B?
    Technical datasheet for WS2814A with specifications and transmission timings.
    Comparison of data transfer times for WS2812/WS2812S and WS2812B.
    They look different, futhermore, it seems they have one mistake in the datasheet... hm. Maybe we need to adjust the driver.

    It still seems that there is an error in the datasheet:

    I've tried today to use the string with an ESP32 and WLED, with the settings WS2812 it works as I describe above, with setting WS2814 it works completely normally and the bulbs have all the same color.

    So basically you've confirmed that OBK supports WS2812 but WS2814 is not supported?

    I also got myself 2 of these string and I got them working by enhancing OpenBeken.
    At the time of writing this pull request is still open: https://github.com/openshwprojects/OpenBK7231T_App/pull/1736

    I seem to have a newer version than the original post. Mine has 5 channels RGB CCT. This is my configuration:

    Code: text Expand Select all Copy to clipboard
    {
    "vendor": "LSC",
    "bDetailed": "0",
    "name": "Smart OUTDOOR PARTY LIGHTS",
    "model": "outdoor party lights",
    "chip": "BK7231N",
    "board": "CBU",
    "flags": "134217744",
    "pins": {
        "16": "SM16703P_DIN;0"
    },
    "command": "backlog startDriver SM16703P; SM16703P_Init 15 RGBWC"
}


    For 4 channels try
    Code: text Expand Select all Copy to clipboard
    backlog startDriver SM16703P; SM16703P_Init 15 RGBW
    or
    Code: text Expand Select all Copy to clipboard
    backlog startDriver SM16703P; SM16703P_Init 15 RGBC
    as start-up command instead.

Topic summary

LABEL_AI_GENERATED
The discussion centers on an LSC Smart Outdoor Party Light string where flashing works, but normal color output is wrong: when all LEDs are switched on they show different colors instead of matching, and a blue command produces mixed red/green/blue bulbs. The bulbs contain WS2814A chips, while the original driver attempt used SM1670P/SM16703P, which only handled RGB and did not support the white channels correctly. Datasheet inconsistencies for WS2814A were noted, including timing and protocol confusion. Testing with ESP32 and WLED confirmed that the string behaves incorrectly under WS2812 settings but works normally when configured as WS2814, indicating the need for proper WS2814 support and correct RGBW/WRGB channel mapping in the driver. Later, another user reported a newer 5-channel RGBWC version and provided OpenBeken configuration using SM16703P with custom channel setup.
