Hi! I made an account to report success with a bulb I'd never seen before and absolutely had to have:
https://www.feit.com/products/st19-curved-fil...ogle-decorative-smart-bulb-st2160-rgbw-fil-ag
It uses a Tuya CBLC5 module featuring a BK7231N connected to an i2c PWM controller.
I was able to destructively gain access by peeling the base screw off. Found RX1, TX1 and RST according to the datasheet:
https://developer.tuya.com/en/docs/iot/cblc5-module-datasheet?id=Ka07iqyusq1wm
They're behind a capacitor and under thermal paste, but I was able to solder on a UART adapter and flash it using the flash tool.
It failed a few times until I lowered to 115200 baud.
Finally, I pulled the base screw off another dead bulb and electrical taped it all back together.
It's mostly working with MQTT and Home Assistant now!
I've noticed it doesn't take transition time into account - future feature, or am I doing it wrong?
Thanks so much for this project!
