    ok. just sure be sure, you've tried a different browser/incognito etc? no JS blocking add-on or anything? (assuming JS is required for the buttons)

    So, after hours of try'n'error i bring it back to work!
    Don't ask me what i've done, can not say what brings it back. Speed option works clean.
    The only problem i have is:
    If i set first cw or ww and then activate the "Rainbow" effect this works but the white LEDs stays on. I have to activate RGB Mode first, then the white LEDs toggles to off.
    I think these should toggle off if RGB is toggle on.
    Now here are my actually settings.
    User interface for controlling LED lighting with various configuration options. Screenshot of the Tuya device configuration interface showing LED settings. Screenshot of a configuration file editor showing the file /autoexec.bat with saved start commands for drivers.

    >>21131094would be great. Is there an option to start them from homeassistant? if I first enable the LED with Rainbow, the white LED toggles also to on so that RGB, WW, and CW are on. So I have to set RGB to a color and activate rainbow, then only RGB works.

    I have no idea either, but it works ok now?

    Oops, you are right, sorry:

    I will try to fix it now

    works, had no problems with the controller.

    I'm looking forward to it! Thank you :-)

    I've made an OTA update to version 1.17.630, now it works with CW and WW, PWM 5 at Pin 24, PWM 4 at Pin 9 works for me. but if I will toggle off while PixelAnim is playing the LEDs stay on, only stop moving. to toggle off I have first set to RGB or white, then I can toggle off. it seems PixelAnim makes a pause because if I toggle on again the PixelAnim starts from the position it stops before.

    Maybe there is an error at my pins ?

    Perfect! I can find no errors, switch from everything to everything works perfectly with version 1.17.632.
    Thank you very much!

    Now, you've asked how to invoke animations from HA?
    The most basic way to do it is to call the Anim (with space and index) command via, for example, MQTT:
    See how to execute commands:
    https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/mqttTopics.md
    You can make a button in HA and it will change animations accordingly.

    This works fine for testing, can use all 3 effects and can toogle off/on in Homeassistant, great :-)

    How did you create buttons, can you share yaml?

    Im think about buttons for brightness ans speed, what are there the options ?

    Wait, brightness? Brightness should be already visible thanks to our Hass Discovery which already works for RGBCW lights (non-animated ones, but still). Are you saying that it's missing? There may be more things to fix.
    Or maybe you haven't done simple hass discovery yet?

    This is old style Yaml, we also have a new HASS discovery:



    I am, however, not sure how well it works with per pixel LED strips. They should be currently visible as a single light.

    Hi there! I'm testing with this strip and wled because I broke one controller.
    So I want to build a new controller with an esp8266 D1 mini.

    Colour is working perfect but I can't get the white channels working (gpio 12).
    If I connect the pins to the ESP (gpio 13 & 15) they are both on but I can not control them and the esp becomes very very warm.

    Do you have a tip for me ?

    Close-up of an LED strip with pins labeled with colors and descriptions: +24V VCC, D0, GND, CW, CC.

    Thank you !

    Greetings

    You can't power C/W LEDs that way. You need to use the LED driver chips/transistors that were on the device PCB. Transistors are needed because ESP8266 does not have enough pin current capability (nor the voltage) to power such LEDs.

    Sample schematic from google (not verified, you may also need a pulldown):

    I think there are many cheap MOSFETs that could do the job, but they may often be in SMD package and you would need to solder it on a proto board.

Topic summary

The discussion revolves around the LSC Smart Digital LED Strip, specifically the 2x5m RGBCW model featuring BK7231N and SM16703P chipsets. Users are exploring the functionality and control of the RGB and white channels, with a focus on integrating the strip with OpenBeken firmware. Initial challenges included driver compatibility for the SM16703P chipsets, which were compared to WS2812 timings. Progress was made in developing drivers, and users expressed willingness to test new configurations. The conversation also touched on issues with color control, PWM settings, and the need for proper scripting to achieve desired effects. Users shared scripts and troubleshooting tips, while some reported successful integration with Home Assistant for remote control.
