    Hi guys, I am new to the platform and need help. I have a LSC Smart XXL Led Strip with a LN882HK1 chip, I have flashed it https://www.elektroda.com/rtvforum/topic4027545.html and the Open Beken version OpenLN882H_1.17.656 also latest release, but all config/template what I test, I don't get light on.

    Can someone tell me the correct pinout or template?

    Can you show a photo of your device and the exact IC designation?

    Does the firmware on the LN882H boot at all on the LN688HK1?

    Hey, I'm sending a few photos. Unfortunately the print on the chip is not good, I could only decipher it with a magnifying glass.

    Flash ran smoothly.
    Was able to activate hue, Mqtt worked for testing.

    Hello, do you need more information or is this enough?

    Can someone here perhaps give me a working config?

    I had bought 2 strips and have now unpacked the other one, on this one the label of the chip is better recognisable, correct label is LN882HKI - 236AY T16 - AAB M 229.

    Hello, does light control work when you use Relay roles in GPIODoctor instead of PMW?

    Open the "Web App" and find the "GPIO Doctor" tab. Then check each pin with the high and low level setting buttons. Which pins control the LEDs?

    Is there any more detailed information yet? I also have this LED strip.

    I think I have narrowed it down so far.
    "pins": {
    "6": ? -> GPIOA6 -> Data line for addressable LEDs
    "7": "AlwaysHigh;0", -> Switches on the LED voltage
    "11": "PWM;3", -> CW
    "12": "PWM;4", -> WW
    "20": "Btn;0", -> Button
    "21": "IRRecv;0"
    }

    My only problem now is how to get the LEDs (RGB) to work.

    @p.kaczmarek2 maybe you can help me?

    What does this bar offer in the Tuya app? Can I ask for screenshots of the app? Are the LEDs all the same colour, or are they WS2812B? Are you able to search for the pins that light the LEDs using GPIODoctor?

    Unfortunately, I have never used the Tuya app.
    They are addressable LEDs, so there is only one data line. I looked at the traces and it should be pin 6.
    I have used the strip once with a Bk chip with 16703 and the colours are different, but I could never change colour.

    On the back it says something about WS2811CCT.

    I have the same problem. I have managed to flash the controller. I've already played around a bit in GPIODoctor, but I can't get the warm white and cold white LEDs to light up. The RGB LEDs light up permanently on white, but not at the possible brightness and also not at full length.
    In between, a few "compartments" have flashed in different colours. Has anyone managed to configure the LEDs?

    Is there already a solution for this strip? I also have some lying around that I would like to free from Tuya.

Topic summary

The discussion centers on the LSC Smart XXL LED Strip equipped with the LN882HK1 chip, focusing on obtaining the correct pinout and configuration template to enable LED functionality after flashing with Open Beken firmware (OpenLN882H_1.17.656). The user reports successful flashing and partial activation of features like Hue and MQTT, but the LEDs do not light up as expected. Attempts to identify the correct GPIO pins using the "GPIO Doctor" tool reveal potential pin assignments: GPIOA6 as the data line for addressable LEDs, a pin set to always high for LED voltage, and PWM pins for cold white (CW) and warm white (WW) channels. The LED strip uses addressable LEDs, possibly WS2811CCT type, with a single data line. Some users report RGB LEDs lighting permanently white but without proper brightness control or full length activation, and occasional color flashes in segments. The community seeks a working configuration or template, with no definitive solution provided. Additional details include weak Wi-Fi RSSI, boot status, and MQTT state. The Tuya app's role and LED control via relay roles versus PWM are also discussed but remain unresolved.
