C:\Windows\system32>python -m esptool --no-stub chip_id esptool.py v4.7.0 Found 1 serial ports Serial port COM3 Connecting.... Detecting chip type...

Okay, tried python -m esptool erase_flash and python -m esptool --before default_reset --after hard_reset --chip esp8266 --baud 460800 write_flash 0x0 /cointhing_v1.7.0.bin 0x200000 /spiffs_v1.7.0.bin Also changed USB cable, it works!

But would it be possible add 7 day Chart Period?
