    I note that this device has been mentioned before but seemed to be unresolved Here, the one I am submitting appears to be a slightly different version of it, it may also go by a different device name apologies if it does I had a good look but couldn't find it.

    PCB with Tuya CB3S module inside a casing. A spool of LED strip with purple LEDs on, lying on a desk with a control button on the cable. LED strip wound on a spool with partially lit blue diodes and a connected cable, featuring a white controller with a button. Four-pin plug connector on a green surface. A white device with a button and USB cable, resting on a green mat. Close-up of a circuit board with a Tuya CB3S module and various electronic components. Green PCB with various electronic components and wires. White LED controller model iH001 with a label indicating compatibility with Amazon Alexa.

    Board: Tuya CB3S

    Pins:
    P8 PWM 0
    P9 Btn 0
    P24 PWM 1
    P26 PWM 2

    Kia ora divadiow,

    If its best practice, I'm happy to change the channels.

    well, I never knew that! fair enough.

    You'd have complained about the colours being wrong or not working anyway, so seems obvious now.

    >>21234797 All good, was a good exercise in understanding PWM some more with OBK, so I appreciate you pointing it out.

    Thanks for doing a pull for the config as well :-)

    Thank you, merged. Device should be soon live at:
    https://openbekeniot.github.io/webapp/devicesList.html

    Channel indexes can start with 0.

    You could get more functionality of this device by using Btn_SmartLED, altough this button code itself could use more tuning.

    This LED controller can be also repurposed to 3x white strip independent control with PwmToggler.

    Added after 47 [seconds]:

    EDIT: I can also see it has 5 transistors? So you can easily use it as RGBCW.

    Thanks will check this out, was initially replicating tuya stock functionality so will likely do more.

    I also note the IR pads on the underside of the PCB and dumped tuya config seems to indicate P14 for their use, I imagine adding an IR diode would be relatively easy.
