LSC Smart Panel Lights (EAN: 8718964243419, OPENBK7231N) RGB and Warm White Output Configuration

LSC Smart Panel Lights


EAN: 8718964243419
OPENBK7231N

How to Flash: UART

PINS are all easy to solder on the backside of the controller; only 2 screws needed to open it.

PINOUT:
P9: SM16703P_DIN
P24: Warm White LED
P26: IRRECV
P28: Button

Works great but my problem is to bring the software to use RGB for color and Cold White and the Warm white output to use as Warm white anybody an idea
AI: Which firmware or software are you currently using or planning to flash on the controller (e.g., OpenBK7231N, Tasmota, ESPHome, etc.)?
OpenBK7231N
AI: Have you already tried any specific software configurations or templates to set up the RGB, Cold White, and Warm White outputs, and if so, what did you try and what was the result?
4. Configuration Attempts

Attempt A – RGBCW Mode (FAILED)
- Warm White configured as LED
- RGBCW / temperature flags enabled
Result:
- Warm White mixed into RGB
- Temperature slider appeared
- RGB pulled Warm White
Conclusion: Not usable.


Attempt B – PWM Warm White RGB (WORKING)
- Warm White on PWM (Channel 4)
- SM16703P used only for RGB
Result:
- RGB correct
- Warm White independent
- Two toggles appear (expected)


Attempt C – CW Emulation via RGB (FAILED)
- Emulate Cool White with RGB enabled
Result:
- Incorrect color mixing
- Warm White leaked into RGB

there was a similar thing here but that post describes a different setup - you seem to have a PWM (?) WW?

>>21820943 and this he says they only have 3-pin output; I have a 4-pin output "Power" "Data" "WW PWM" "GND"

It looks to me the SM16703P driver is the problem. I mean it didn't set the channels right; it looks; it thinks that the 4th channel is the only RGB channel, so it maps it to red, so every time I set warm white, red WW will go at the same time.

not a solution, but here's Easy Flasher's extraction verbatim, for the record



Added after 1 [minutes]:

as a side note EF seems to have missed key_pin:28

Problem stays had anybpdy an idea ?

not from me, but I did see @p.kaczmarek2 doing something here, off the back of a GitHub Issues post, that might relate https://github.com/openshwprojects/OpenBK7231T_App/pull/1980

https://github.com/openshwprojects/OpenBK7231T_App/issues/1965

Can you post a OpenBK configuration here?

With the newest version the red problem ist solved but warmwhite didnt work .

Hey, did you manage to get this working?

is anyone in a position to get a nice hi-res clear image of the PCB, especially this area so the traces from each leg of the BK7231N is visible?

>>21847150

I gotcha.

Hope it will help.

cool, cheers. I was curious to know if any attention should be given to P14/P15



doesn't seem like they are connected to anything, so it seems no.

>>21847486
Doesn't like it, no.

Where did it came from? It's impossible and unlikely on Beken. WS2812 and similar are always using P16. I need a source of this P9 pin information.

>>21847562 So you mean like?

"pins": {
"16": "SM16703P_DIN;0",
"24": "PWM;4",
"26": "IRRecv;0",
"28": "Btn;1"}

I used the trial-and-error method and it works. I can use effects on RGB, and with the older firmware I can use a second slider for the warm white. I have over 20 panels and it works. The problem on the old firmware was: every time I changed the WW channel, the R channel followed. Now, with the new firmware, when I set the WW channel to CH4, it didn't work. I can make a video; I have two controllers on old and new firmware.

regarding the factory behaviour of the white channel vs RGB, it kind of looks like control is separated in the Tuya app.



if you put white down to 0/off brightness and then play with colour settings only, does the white come on at all?

>>21849009 Using the config from this thread, I get these controls. If I put the brightness down, nothing turns on anymore

Anything I can do to assist to get to a solution? I'm not that familiar with OpenBK.

So here the Config with Firmware version what i used for RGB

Release: Built on Feb 13 2026 10:32:23 version 1.18.260

Have you tried this version?
https://github.com/openshwprojects/OpenBK7231T_App/pull/1980

>>21854560

When I try this, I get 'invalid command: delay' and the pixelanim starts

I can send anyone a controller and a panel who can program this shit 🤣. Have 4 controllers here
