    It will be very hard to solder in case of this particular device. Direct SM16703 control would require hardware SPI pin, ,MOSI, namely P16, to be connected to the LED strip. The P16 is not easily available on CB2S module. You can only route it yourself by soldering to QFN pin.

    Still, there are some other LED strip products around which comes without MCU and they use P16 in a way I said to control SM16703

    Here are some of the captured fnID's so far.

    fnID 20 is bool power on/off with values 0 and 1
    fnID 21 is mode of operation 1 (dimmer), 2 (scenes) and 3 (music)
    fnID 24 is brightness control (and possibly some preset colors) as a string - preceded by fnID21 1
    fnID 25 is brightness setting in scene mode as a string - preceded by fnID21 2
    fnID 26 is off timer in seconds
    fnID 27 is a data from the phone microphone if music mode is enabled as a string - preceded by fnID21 3
    fnID 28 are the values form the color wheel selector as a string

    The rest will follow.

    User interface of OpenBK7231N with LED controls.

    Progress so far.

    Power toggle works, adding scenes works, color picking works, brightness control for stable color works so far (probably music selector as well)

    TODO - brightness control for scenes, adding more scenes and figuring out if color temperature is possible to set.

    Good progress ;)

    It turns out that dpID 24 is the same as in the @nethawk topic here:

    https://www.elektroda.com/rtvforum/topic3982779.html#20656814
    So this can work:

    This is the working autoexec.bat that will bring you functionality that we were able to figure out so far, more to follow as it is somewhat complicated.

    Be aware color temperature selector is not working at this point so don't use it!!

    Test other features and post here what you have and any findings that you may come across - thank you!

    Added Music mode...

    So far HA integration is not working as intended so we suggest not to use it with HA at this point, we will post more updates as we make progress.

    are hardcoded identifiers or animation data somehow compiled, still working on it.

    At least we know they also include brightness data.
    Here is the same animation with different level of brightness:

    See? Only 3 characters change:
    Screenshot of codes and data in HEX format, showing different brightness values.
    I wonder what is the meaning of the other characters here.

    NOTE: those are ASCII strings that forms characters that looks like HEX data....

    3e8 at full bright looks like 1000 in decimal

    I have done some testing and here are my comments so far.

    1.Using the autoexex content that @DeDaMrAz mentioned above I somehow have 2 toggle buttons. I have no idea why (running version 1.17.232)
    Pressing on Toggle 20 doesn't seem to do anything. Toggle Light - turns on/off the light.

    Screenshot of LED lighting control interface with various options.

    2. Brightness works OK with the light and the scenes.

    3. RGB Color - is not right for me. When I select RED in the RGB picker the led are blue on the light. If I select BLUE on the RGB picker the light is orange. GREEN works OK. Yellow gives a very light blue. A bit of mismatch.

    4. As you have mentioned Temperature does not work right now.

    5. The Scenes all work fine.

    6. Music Mode - it seems to respond much better to vibrations rather than music. For example I have the stereo up and nothing happens. But if I tap my finger on the surface where the light is on there is a response. If there is a way in increase the microphone sensitivity maybe that will fix this. But not sure if possible.

    One addition that I think will be good to have maybe will be a button to go back from a Scene to light. At the moment if you press a Scene button the only way to stop it and display light only is through the RGB picker to pick a color. Then the scene stops and the light shows that color. A button to show Cool white or warm white for example might add a bit more functionality.

    Hopefully you guys can mage to add the rest of the functions available through Tuya/remote - Shut Down timer, Sensitivity, Speed:

    Remote control with button descriptions

    And of course HA integration :)

    If you have anything else in mind that could be added/implemented to such a device please add it!! :)

    Many thanks guys for your help with freeing this device for Tuya cloud!![/img]

    You can add this to existing autoexec file to enable light only toggle:

    Code: text Expand Select all Copy to clipboard
    startDriver httpButtons
setButtonEnabled 7 1
setButtonLabel 7 "Light mode"
setButtonCommand 7 "tuyaMcu_sendState 21 4 1" 


    Every 7 represents button placement so adjust that to your needs.

    Also can you post some logs from your device when doing color change?

    Microphone is encapsulated inside a sealed plastic box, wrapped in a heat shrink tubing :) I am testing with it exposed and it works fine, but there are no information on gain modification...yet ;)

    Hope this helps - let me know if you need more or anything else.

    Light Button works perfect. And thank you for the explanation - now I know how to add more buttons if I need to.

    Edit - at the top when I pick red color it actually shows BLUE.

    Glad to be of help.

    Your logs are kind of weird, like they have inverted color bytes...

    mine:

    yours:
    55 AA 03 07 00 10 18 03 00 0C 30 30 30 30 30 33 64 65 30 33 63 30 22 - red

    Underline are color selection values (obviously we didn't pick exact same colors but close enough to compare) but the bold bytes are messed up somehow.

    Maybe a weird timing issue? Do you have any flags set?

    Not sure why - I did fiddle around with the remote a while back while I was trying to pair it with Tuya. I believe the remote has some capability to do "stuff" - like reassign button functions, maybe colors, etc not sure exactly - maybe there is something stored somewhere (related to IR?) in for whatever changed back then.

    Maybe there is a way to wipe all this? Already tried to reset the device back to factory settings and it didn't change anything.

    Only flag 10 was set for it. I disabled it. Rebooting now.
    After reboot, it's the same as before.

    Ok, got it figured out :facepalm: last bytes are actually brightness values :D learning as we go so I apologize if I was misleading you.

    can you try these commands :

    tuyaMCU_sendColor 24 1 0 0 1 (you should get RED)
    tuyaMCU_sendColor 24 0 1 0 1 (you should get GREEN)
    tuyaMCU_sendColor 24 0 0 1 1 (you should get BLUE)

    You can try then in Logs tab, on the bottom you have a command line input. Also grab the log for these commands pls.

    Pressing on Toggle 20 doesn't seem to do anything. Toggle Light - turns on/off the light.

    No. It is not the fault of this autoexec.bat. It's just that you have previously set channel 20 type to "Toggle" and it's still kept in the settings.

    Go to Web App, then find channel 20 on channel types list and change the type back to default one.

    Those are pin settings. They are used to set the types of physical IO pins of the device.

    You are looking for channel types. They should be next to the right. Channel types are used to set the types of the channels, which are like virtual variables containers. They are non-physical.


    BTW: So you have swapped colors while they are OK on @DeDaMrAz device?

    Silly me - learning :) found it in the next column as you have said. Second button is gone now.

    In regards to the RGB - I have never swapped anything intentionally. It might have been by mistake while trying the IR remote.
    That remote has some strange settings - it looks like it can change remote button functions, LED colors (I think) and more. Not sure because the English in the manual they sent me is not that great:

    It doesn't seem like it has option to swap colors. Maybe you have slightly different model?

    @DeDaMrAz can you confirm whether colors on your piece are correctly displayed?

    I think if you long press the Play/Pause button on the remote, it takes you into some kind of submenu where it all gets confusing. I would suggest not to do that as settings might change on a device.
    For example, this morning I managed to somehow change the function of the Music function of the device - when pressing the Music Mode in the app, it was changing colors instead of going into the Music Mode. Somehow I managed to put it back to what it was originally. Don't ask me how as I have no idea - I tried too many things.

    I remember that after I flashed the device to OBK and got TuyaMCU loaded (that's a few months/weeks ago), I did get into that submenu and tried a few things to get out of it. I think that is when the RGB settings on the device changed. That's what I believe happened - what actually happened might be something else entirely :)

    On my OBK home page, all color changes are working - confirmed.

    Interesting that the sendColor command is working OK for @mnm11


    Added after 2 [hours] 3 [minutes]:

    I think we are close to figuring out what is wrong with HA integration and will post here once we have it figured and solved ;)

    Will not stop until we got it fully functional.

    To be continued.

    @mnm11

    We need a bigger sample of tests, can you update your device to build 1.17.237 and add it to HA to test if color change will work for you? The issue that I am facing is that I can change color only a certain number of times (let's say 7 or 8 times) and then the device will become unresponsive to color change until I power cycle the light by on/off switch. Can you test that maybe?

    We also have some progress in the mic sensitivity area, fnID's 52 and 53 are probably responsible for setting that in a range of 0000010100 (lowest) to 00000101F4 (highest), but we will have to play around a bit more to be sure if that is the case.

    NOTE: WW to CW color temp is still not working in HA or in OBK home page - yet to figure it out.

    I have tried and for me it changes the color just fine.
    I am using the RGB wheel to do this. But it never stops changing color.

    When I press any of the colors in the top row (the favorites colors) the light just goes off. This is what I have in there:

    Four circles in different shades of orange and white on a black background.

    If press colors on the second row it brings it back but it doesn't display the correct colors - it mostly goes to white color. This is what I have in the second row:

    Four round color swatches in pastel shades: blue, purple, pink, and orange.

    I have managed to change the RGB order to something better than what was before. This is the process (maybe you should not do it as it might mess up your colors too) all done from the remote:
    1. Power off
    2. Press and hold Play until the device is showing colors
    3. Press < or > to change the colors that are displayed
    4. Press On/OFF to save
    I selected half of the device to show red and the other half green. This is the closest I can get to RGB.

    Looking at that PDF they have sent me I noticed this:

    "Lighting mode:
    1, short button function: press the button to enter the lighting mode, and each short press will switch between cold light, warm light and neutral light; Non-independent heating and cooling lamp products, only energy mixed color RGB white light;"

    Not really sure what to make of it, but it sounds like there are 3 white colors (in the first part of that paragraph) but then it sounds like mixing the RGB colors will create the white light (in the second part of the paragraph)?

    When I press the light button all I get is cool white regardless of how many times I press it.

    Let me know if you want me to test anything else - but this will be tomorrow as now is 2:14Am here and I need to get some sleep.

    That is the color temp predefined selector and we are aware of it not working, still or should I say yet :)

    Thank you for your report, we will continue to play with this device and post updates here as we figure them out.

    BTW you can play with music mode by utilizing these commands:

    backlog tuyaMcu_sendState 21 4 3; tuyaMcu_sendState 51 3 0000010100; tuyaMcu_sendState 52 3 0000010100; tuyaMcu_sendState 53 2 300;

    by changing last two values in 51 and 52 (ie 00000101F4 instead of 0000010100) and both of them you can get a different response to music similar to different scenes. Still not sure what 53 is doing but default value is 300 and you can play and change that value as well and let as know if you observe any meaningfull change.

    Stay tuned and if you like what we do please consider supporting us by spreading the word or in any other way, thanks.

    EDIT: figured explanation for those commands will be nice so:
    tuyaMcu_sendState 21 4 3 - command fnID(number) [data_type] [value for that data type]
    tuyaMcu_sendState - this is a command for sending various values that TuyaMCU recognizes
    21 - is the fnID that is decoded based on the behavior of the original FW and let's call it designator for certain values that again TuyaMCU understands
    4 - in this case is a Enum type of data (3 would be sting data type and is RAW data like that 0000010100 from above, 2 is a Val(ue) in some predefined range ie 0-100 and 1 is a Bool with values 0 or 1)
    3 - in this case is that Enum value that is representing mode of operation (1 being light mode, 2 being scene mode and 3 being music mode)

    So to summarize tuyaMcu_sendState 21 4 3 translates to - command is tuyaMCU_sendState to a fnID21 as data type 4 (which is Enum, so 1, 2 or 3 in this case) and 3 is discovered mode to be music in this case.

    Similar here tuyaMcu_sendState 51 3 0000010100 - command is tuyaMCU_sentState to fnID51 as data type 3 (raw) and then raw bytes 000001010.

    And finally you can send multiple commands at once with backlog feature in the following format - backlog [whatever supported function]; [another supported function]; [another]; etc but you have to have ; separating them.

    Hope it helps a bit.

    @DeDaMrAz - Thank you for making progress with this and on the commands guide :)

    I have tested the commands you suggested and I see what you mean. It is a nice addition to the music scene.

    In regards to tuyaMcu_sendState 53 2 300, I got some more info. You have to use the remote to see the effects of this.

    tuyaMcu_sendState 53 2 0 = If you use the RGB wheel on the remote, you will see that as you rotate your finger on it, the color change is pretty instant on the light.
    tuyaMcu_sendState 53 2 8000 = If you use the RGB wheel on the remote, you will see that as you rotate your finger on it, the color change on the light is heavily delayed.

    I have used these extremes (0 and 8000) as with smaller values, I could not see what the effect of the values were.

    Not sure what to make of this - is it a delayed change of color or is it more like Flag18 (smooth transition) in OBK?

Topic summary

The discussion centers on the compatibility and firmware flashing of a Tuya waterproof LED light purchased from AliExpress, featuring BK7231N chipset and controlled via a TuyaMCU with an SM16703 LED driver. The main focus is on using Cloudcutter to flash OpenBK (OBK) firmware, determining whether the device uses the N or T version, and verifying driver support and GPIO configurations. Initial attempts to use the SM16703P driver in OBK showed limited success due to the device employing a TuyaMCU protocol rather than direct LED driver control. The device supports multiple DPIDs for functions such as power toggle, mode selection, color, scenes, timer, and music sync via microphone. Users successfully detached the device from the Tuya cloud using Cloudcutter, retaining full local functionality controlled through LocalTuya in Home Assistant (HA). Color control commands were developed and tested, revealing color channel mismatches (BGR vs RGB) adjustable via remote settings. Warm/cold white temperature control is not supported in the original firmware and remains unimplemented in OBK. Firmware backups were made to facilitate analysis. Advanced users explored hardware modifications to bypass TuyaMCU for direct SM16703 or WS2812B LED control, but this requires complex soldering due to unavailable SPI pins on the CB2S/CB3S modules. A comprehensive autoexec.bat script was shared to enable LED control, scene selection, and music mode via OBK commands. Issues such as LED blinking during pairing, color inversion, and device behavior after mode changes were addressed with command sequences and flag settings (e.g., TuyaMCU queue flag 43). Integration with HA was improved with MQTT commands and button configurations. The community continues to refine support, with ongoing development to rewrite the TuyaMCU driver and enhance device functionality, including animation triggers and improved color temperature handling. The device's IR remote has advanced features that can alter button functions and color mappings, which may cause unexpected behavior if misconfigured.
