    Currently you also need to manually configure WS2812B-style LEDs, see related topics:
    OpenBeken WS2812B animations - new HTTP panel integration, PixelAnim driver
    The CW + RGB integration will be supported soon in next OBK releases, so it's possible that by the time you read it, it will work out of the box.

    Hello there !
    Do you have success with this led strip ?
    I bought one yesterday, did a backup , extract config , but no way to get some light after flashing ...

    hello,
    i didn't start yet to have colour leds. I'm just trying right now to have cool/warm white working. I have no autoexec.bat right now.
    BTW, i've also tried the esphome/libretiny port for this led strip and i also have no light at all, no white, no colours.

    We need more information and you need to try the RGB. Maybe they have now alternate CW control, where second pin is used to control brightness. Try playing with GPIO Doctor on PWM pins. Make some detailed photos, what is connected where?

    I think the game is over for now .. I don't have power any more to the board. I have 24V on input but the board is not powered, thinking something went wrong.
    The BK7231N is ok when powered directly from pin but not when powered from the 24V power supply.

    Maybe it's just a mechanical damage. Can you check where voltage reaches and where it doesn't? How the step down converter looks like?

    Here are the photos of the insides:
    Image of a green circuit board with various connectors and pin labels. Electronic board with several colored wires connected at the top.


    and on the box there is .1 at the end of product code so i guess that means it's a new revision Energy label for LSC Smart Connect product with energy class F.
    I didn't run PixelAnim driver because I have no clue what pins are relating to rgb led's and/or CW

    We actually know which pin is used for LED RGBs, the ones that are per-pixel addressable. It's always P16, hardware SPI output. That's because hardware SPI is used to control the WS2812 LEDs.

    For a start, I'd suggest following PixelAnim/WS2812 topic (linked few posts above) and trying to get some RGB light.

    I would also check if 24V is present on LEDs, because some devices might have extra pin used to toggle power on and off for them, sometimes to dim them. Check it with multimeter.
    Probably the transistor between 24 in and out is used:
    View of a circuit board with marked INPUT 24V locations and labels OUT and a question mark on other pins.
    If there is 0V at output of transistor, try setting each pin in GPIODoctor to 1 and observe which enables voltage for the strip. It will be probably one of PWM pins.

Topic summary

✨ The discussion focuses on the LSC Smart Connect XXL LED strip (model 3202086), an individually addressable RGBIC + CCT LED strip based on the BK7231N chip, compatible with OpenBK7231T (OBK) firmware. Users share experiences flashing the device with OBK and ESPHome, aiming to achieve control similar to Tasmota/ESPHome for cloud-free operation. Key challenges include configuring the PixelAnim driver for WS2812B-like LEDs on hardware SPI pin P16, managing additional PWM channels for cold/warm white (CW) LEDs, and ensuring proper 24V power delivery through onboard step-down converters and transistor switches. Several users provide JSON device configurations extracted from Tuya firmware, highlighting pin assignments: microphone on P23, IR receiver on P26, CW LED on P6, and RGB LEDs on P16. Attempts to light the LEDs using PixelAnim and SM16703P drivers initially failed, prompting suggestions to verify power lines and PWM pin control via GPIO Doctor. Later contributions include ESPHome YAML configurations for both 3202086.1 and 3202086.2 revisions, demonstrating working setups with beken_spi_led_strip platform for RGB LEDs and libretiny_pwm outputs for CW channels, enabling various lighting effects and proper color temperature control. The thread also includes requests for Tuya flash dumps and internal device photos to aid in protocol analysis and hardware understanding.

FAQ

TL;DR: 1x10m RGBIC+CCT LSC 3202086 runs BK7231N; “Currently you also need to manually configure WS2812B-style LEDs.” Flash OpenBeken, set WS2812/PixelAnim, and map CW PWM pins per revision. [Elektroda, p.kaczmarek2, post #21101486]

Why it matters: This helps DIYers flashing OBK/ESPHome go cloud-free, fix “no light” issues, and avoid revision-specific pin traps.

Quick Facts

What is the LSC 3202086 and can I flash OpenBeken for cloud-free control?

It’s an LSC Smart Led Strip 1x10m RGBIC + CCT using a BK7231N (CBU) Wi-Fi SoC. OpenBeken supports this chip. The strip has individually addressable RGB LEDs plus separate PWM channels for white. WS2812-style LEDs require manual setup in OBK’s PixelAnim panel. [Elektroda, p.kaczmarek2, post #21101486]

Which pin drives the addressable RGB LEDs on this controller?

P16 (hardware SPI MOSI) drives the per-pixel RGB data. As the maintainer notes, “It’s always P16, hardware SPI output.” Use this pin with SM16703P/WS2812 drivers in OpenBeken or beken_spi_led_strip in ESPHome. [Elektroda, p.kaczmarek2, post #21336982]

How many addressable LEDs should I configure?

Typical configuration for revision 3202086.1 sets LedNum to 40. If your effects look truncated or mirrored, adjust this count to match your strip length. The Tuya extract shows LedNum: 40 for that hardware. [Elektroda, divadiow, post #21337134]

What PWM frequency should I use for the CW/WW channels?

Use 1000 Hz PWM for the white channels. This value comes from the device’s Tuya configuration and works well with BK7231N-driven drivers. [Elektroda, divadiow, post #21337134]

What pins and ESPHome mapping work for LSC 3202086.1?

Use P16 for RGB data, CW on P6, WW on P24, and power/control on P22. IR receiver is P26 and the on-board button is P20. Example ESPHome sets num_leds: 40 and beken_spi_led_strip on P16. [Elektroda, matiserv4, post #21362240]

What pins and ESPHome mapping work for LSC 3202086.2?

Use P16 for RGB data, CW on P9, WW on P24, and power/control on P6. IR receiver is P26 and the button is P7. Example ESPHome uses num_leds: 40 with beken_spi_led_strip and power_supply on P6. [Elektroda, xpeng, post #21358222]

How do I enable RGB with PixelAnim in OpenBeken?

Run these commands (e.g., in autoexec):
  1. startDriver SM16703P
  2. SM16703P_Init 16
  3. startDriver PixelAnim Then set pixel count and toggle power in the UI. This initializes WS2812 via P16. [Elektroda, Dratii, post #21337021]

I flashed successfully, but nothing lights. How do I fix it?

Verify 24 V is present on the strip rails. Many boards gate LED power with a transistor, enabled by a control pin. Use GPIODoctor to set suspected PWM/control pins high and watch for 24 V at the strip and any glow. Then configure PixelAnim on P16 to confirm RGB output. [Elektroda, p.kaczmarek2, post #21336982]

What does the power/control pin do on these boards?

It enables the LED power path, often gating 24 V to the strip. Some designs also modulate brightness there. If LEDs stay dark, assert this pin before driving CW/WW or RGB. The control sits between 24 V input and LED output via a transistor. [Elektroda, p.kaczmarek2, post #21336982]

How can I find the correct CW/WW pins if they’re unknown?

Open GPIODoctor and toggle each PWM-capable pin while measuring LED power. “Try playing with GPIO Doctor on PWM pins.” Note which pin brings up 24 V or lights cold/warm channels, then map those to CW/WW. [Elektroda, p.kaczmarek2, post #21327629]

Does OpenBeken now support combined RGBIC + CW?

Development progressed: “RGB IC + CW PWMs” was tested and working in the simulator. If your build predates this, use manual PixelAnim plus PWM. Update to a recent OBK release for integrated control. [Elektroda, p.kaczmarek2, post #21101992]

I lost power from 24 V input after tinkering. What should I check?

Inspect for mechanical damage and trace voltage from the 24 V jack through the step-down converter. Measure where voltage stops. If the regulator or fuse path is open, repair it before further tests. Provide clear board photos to aid diagnosis. [Elektroda, p.kaczmarek2, post #21327640]

BK7231N runs on 3.3 V but the board stays dark on 24 V—what does this indicate?

This points to a failed 24 V power path or regulator stage. One user saw 24 V at input, yet the controller board was unpowered, while the BK7231N worked when powered directly. Inspect the input path and regulator. [Elektroda, snakesrules94, post #21327635]

Is there a starter OpenBeken template I can import?

Yes. A base OBK template was shared with button on P7 and PWM on P9 (CW) and P24 (WW). WS2812 requires manual configuration via PixelAnim. Use it as a starting point and adjust for your revision. [Elektroda, p.kaczmarek2, post #21101486]
