Yewelink/Tuya WiFi Touch wall light switch

[enesbcs]

I flashed the standard ESPEasy_R120_4096.bin, which did not work and ESPEasy_Mega_P165_4M_1MS_lwip20 from this discussion. Neither caused the ESP_-access point to show.
Reattaching the board to the rest of the device make all LEDs light up - it knows somethings wrong !
Will try more later.

The neighboring project uses 1M firmware with no SPIFFS, and esptool with "dout" mode, i suppose you did not.

I got this similar device today but unfortunately I cannot get it into reset mode to pair with phone app. So I decided, if I can flash it with different firmware and found this post.

Did you guys able to flash it and get it worked? If so, how.

By the way, the

CR302 B751T004BG

is a capacitaive touch IC
