Bulb RGB Color Interchange issue - Syska 12W Bulb

Question

Hello All,

I recently migrated an ESP home bulb to Openbeken as I was observing flickering on the ESP firmware.

Openbenekn migration was smooth, flickering issue vanished and the bulb works fine now... however I have noticed the RGBCW colors have interchanged:

Actual RGB Current RGB
R 0 G
G 1 C
B 2 W
C 3 R
W 4 B

Below are the only two pins I have configured in settings

],
"pins": {
"7": "BP5758D_DAT;0",
"8": "BP5758D_CLK;0"
},

Please help

It looks like your device is using PWMs. Do you have 5 PWM pins set in config?

Can you do Tuya config extraction?

You can also try enabling this flag (but disable it back if it doesn't help):


Flag  8	[LED] Alternate CW light mode (first PWM for warm/cold slider, second for brightness)

Happy to report that I have got the mapping right for the BP5758D Bulb which had color interchange issue. Below is the correct mapping Code: text Expand Select all Copy to clipboardBP5758D_Map 4 3 1 0 2 Below is the template Code: text Expand Select all Copy to clipboard{   vendor: Tuya,   bDetailed: 0,   name: Syska 12-Watt  Wi-Fi LED Bulb,   model: B-22,   chip: BK7231N,   board: TODO,   flags: 134616320,   keywords: [     BP5758D,     bulb,     light   ],   pins: {     7: BP5758D_DAT;0,     8: BP5758D_CLK;0   },   command: BP5758D_Map 4 3 1 0 2,   image:    wiki:  } So the Syska 12-Watt B-22 Wi-Fi LED Bulb has two versions, I have the pin & color mapping settings done the above posts. 1). PWM drivers 2). BP5758D drivers

Hello, you need to do the colors remap. The easiest way to do it is currently via Web App, here: You can try guessing remap or getting one from here:

DCG · Answer

Yes, I did fiddle around with the LED Tools option, and my bulb's actual settings are 4 2 3 1 0... I have applied the above settings, but it's not working. I know I must be doing something wrong.

p.kaczmarek2 · Answer

Did the order of colors change? Try another order of colors.

It is very simple. Enter number 0 for first field, click "apply and set to red" - is it red? If yes, then okay. If not, then enter number 1. Try again. Is it red? Good, check the next field. You can just brute force it...

DCG · Answer

Yes, orders changed and somehow I am just not able to understand how this mapping works.

As of now, only Green, Warm & Cool are perfectly matching... RGB is interchanged for Red & Blue.. but if I just change the numbers for Red & Blue, everything gets messed up.

Also, how do I retain the last power / memory status if there is a power outage...? If the bulb was on and there was a power outage, the bulb doesn't turn back on when the power resumes.

p.kaczmarek2 · Answer

There is a flag for remembering the LED status.

I would say you need to swap the indices that are currently for Red and Blue. Or maybe' let's approach it from a different angle. Can you do Tuya config extraction?

If I try to import the above Jason - I get error - Failed - SyntaxError: Bad escaped character in JSON at position 772.

Device configuration, as extracted from Tuya: 
- BP5758D_DAT on P7
- BP5758D_CLK on P8
- LED remap is 4 2 3 1 0
Device seems to be using CB2L module, which is using BK7231N.
And the Tuya section starts at UNCOMMON POSITION 0

@p.kaczmarek2 Please help with this. I have 3 more bulbs of the same model and need to resolve this one before moving the other bulbs to Openbeken.

p.kaczmarek2 · Answer

Well, we can try another way.

Open console in the Web App, enter:


BP5758D_Map 4 2 3 1 0

Then in main OBK panel, try setting:
- red, and tell me result
- green, and tell me result
- blue, and tell me result
We will adjust that map if it's somehow wrong....

DCG · Answer

@p.kaczmarek2 thanks for the inputs I will check & share the results soon.

I am now in a different situation with another Bulb (same model) however this time the chip seems to be different...
in this Bulb I am getting all the RGBW colors to match perfectly except the Cool white which never gets to display...
I tried changing the RGBCW codes but the Cool white never turns... (only instance I see Cool white is when I move the slider close to warm)

R - Working
G - Working
B - Working
C - Not Working
W - Working

I am using the below Jason code

Yes, all 5 PWMs are set, and below is the Tuya config extracted message.Sorry, no meaningful pins data found. This device may be TuyaMCU or a custom one with no Tuya config data.No module information found, and the Tuya section starts at UNCOMMON POSITION 0Ok, so this did the trick, and I am able to see Cool white being turned on. The only thing is Warm & Cool settings have interchanged...Any way to fix this?

p.kaczmarek2 · Answer

This may mean that you need to change the pin role of fourth channel from PWM to PWM_n. Try and tell me if it helps. By fourth, I mean, red is first, green is second, blue is third, etc...

Perfect everything working now as expected, thanks a ton for your support.. below are the pin settingsCode: text Expand Select all Copy to clipboard  pins: {     6: PWM;3,     7: PWM;5,     8: PWM_n;4,     24: PWM;2,     26: PWM;1Now I will troubleshoot the initial issue with the same model bulb which has BP5758D, I will update you on that------------------For anyone who is looking for the Bulb model number, it's a brand available in India primarily.

Bulb screenshot: model: 492166310 I will add this to devices list.

Okay, I've added both templates to our list: They should be soon live at: Just to confirm, both types of bulb (PWM and BP5758) are using CB2L modules?
