Lesson29- How to use tasmota for KC868-A8 via PCF8574 IIC extend GPIO

[Skankrabbit]

Yes,that is the one I used. When I try to flash that firmware ( KC868-A8-Tasmota-firmware.bin), with ESP-Flasher-dev-macOS, to returns this error and won't flash:

Unexpected error: Error while retrieving firmware file 'https://raw.githubusercontent.com/Jason2866/ESP_Flasher/factory/bootloader/esp32/bin/bootloader_dout_40m.elf': 404 Client Error: Not Found for url: https://raw.githubusercontent.com/Jason2...ut_40m.elf

I can flash the basic ESP32 firmware,
then once connected with wifi, "configure other",,
add the template you provided, 
then upgrade firmware to KC868-A8-Tasmota-firmware.bin,
but it doesn't activate the PCF8574 still. Any ideas?

By the way, my ethernet port still dead any resolutions?
