What silicon powers the Lumary 5/6 inch downlight?
Most units ship with a Tuya CB2L module (BK7231N Wi-Fi SoC) driving a KP18058ESP 5-channel LED controller [Elektroda, swpharis, post #20635449]
[BK7231N/CB2L] Lumary 5/6 Inch Downlight - OpenBeken driver for KP18058esp LED controller
TL;DR
- Lumary 5/6 Inch Downlight uses a BK7231N/CB2L module and a KP18058esp LED controller for an OpenBeken driver setup.
- Accessing the internals requires removing the diffusing filter, undoing 3 screws, unplugging the ribbon cable, and gently prying off the back cover.
- The CB2L module is soldered to the power board, and the plastic housing is very soft and brittle.

Remove diffusing filter.
Undo 3 screws.
Unplug ribbon cable from LED board.
Gently pry off back cover with small flat tool. Plastic is very soft/brittle.

I haven't seen such mounting of CB2L module yet. Do you have a configuration for this device? Or maybe at least a flash dump, so I can extract GPIOs? [Read more]
Best way to dump flash on OSX? I was able to build the BK GUI Flash tool in mono with errors, but it crashes when launched. [Read more]
I don't know this system much. Maybe Python's hid_download_py can work. You can see CB2S (very similar to CB2L) dumping in this video: https://www.youtube.com/watch?v=PKkiqDNFIx8 [Read more]
Python does work - someone posted earlier - https://www.elektroda.com/rtvforum/topic3984791.html Issue was with forms. System.Windows.Forms.dll "The Carbon driver has not been ported to 64bits,... [Read more]
Just got a single pack of one of these and it uses a different module. There isn't consistency. Configuration values are the same. Module firmware from Lumary before flashing was 2.3.x in the Tuya app.... [Read more]
Can you post Tuya Config? So you got BK7231T version that time? [Read more]
https://obrazki.elektroda.pl/4901648200_1687996097_thumb.jpg Already flashed it. Yes it was WB2L with newer firmware. Manufacturer date was sept. 21. Manf date on others was Dec. 21 Added... [Read more]
There are PWM-SDA and PWM-SCL markings on the board. This indicates a "I2C-like" LED driver such as BP5758, SM2135, etc. Please see where are the SDA/SCL signals going. What is the name of the chip? It... [Read more]
It’s a KP18058esp. https://obrazki.elektroda.pl/9598941000_1688044204_thumb.jpg Added after 1 [hours] 45 [minutes]: Pinned it out. https://obrazki.elektroda.pl/2822231400_16880506... [Read more]
Can you check if any of existing LED IC drivers works with that chip? [Read more]
Can you explain more what you are asking please? [Read more]
KP18058 looks like one of those "I2C-like" LED driver chips, where only two digital lines (SDA and SCL) are used to control 5 channels of LEDs. The problem is, KP18058 doesn't seem to be well known. ... [Read more]
More info on this setup - (third revision with SDA). I had a wiring issue in original read. Read @ 115200 Write @ 921600 Other rates fail.

Thanks, this is also helpful, but we still need an insight into the two wire protocol of that device. Can you tell us where it was bought? I've spoken to @dedamraz and he seems to be eager to buy... [Read more]

Thank you @swpharis for the links, ordered placed we will have them by July 11 to analyze and try to support it. [Read more]
Please stand by @swpharis , we will need your help with testing once @dedamraz does packets capture. I wonder how the protocol looks like. Some such LED drivers are using 8 bits per channel, giving us... [Read more]

I received one light type but unfortunately it has TYWE2S module and no KP LED controller :/ awaiting for the other one to arrive. [Read more]
