Cool, then you should be good to go. For the Wroom32, you can just update the board type in the ESPHome YAML file to denky32 (which seems to be a Wroom32 variant from https://registry.platformio.org/platforms/platformio/espressif32/boards), if you have any trouble with it.

No, not as far as I'm aware.
The experience with an ESP has been much more reliable so far than with the previous board and Tuya firmware. I'd say the ESP is worth it.

WS2812 with animations is supported by OBK on BK7231N platform, but T is still pending. See PixelAnim driver info: https://www.elektroda.com/rtvforum/topic4057187.html

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Has there anyone been successful with flashing this WB8 module? I connected wires from the GND, RX1, TX1 test pins (see picture above #6) of the WB8 module to a Serial-UART adapter but was not able to flash. The module was powered via barrel socket, the adapter from USB. But even with several attempts to disconnect and reconnect the module from power the flasher application was not able to communicate. It seems btw that the wiring at least for TX1, RX1, Vcc and GND is the same as for the WB3S module. Now that we have the SPI driver integrated it would be cool if we could reflash the BK7231T chip.

I managed to flash it without any issues, using a CH340 UART adapter connected to the measure points on the back for GND, 3.3V, RX1 and TX1 (the latter two switched on the UART adapter obviously), and without connecting the barrel plug.
I haven't been able to get the LED string to work however.

Topic summary

The discussion revolves around configuring the BK7231T chip installed in Globe Fairy Lights, specifically addressing issues with GPIO configuration and cloud-cutter profiles. Users encountered errors while attempting to read GPIO Tuya configurations and utilize cloud-cutter profiles. Suggestions included using GPIO Doctor to set PWM roles and checking the LED driver type. The LEDs were identified as WS2812B, and users explored options for using an ESP32 to control the lights, as current support for WS2812B on the BK7231T platform is pending. Several users shared their experiences and troubleshooting steps, including disassembly attempts and wiring configurations for Arduino and ESP32 integration.
