I have a problem to upload a sketch to my SONOFF POW.
Tried to upload the sketch OTA-mDNS-SPIFFS but without success.

My goal is to succeed with this POW based on this tutorial "#99 Measuring Power, hacked Sonoff POW, MQTT, Adafruit.io and Home Automation - #99 Measuring Power, hacked Sonoff POW, MQTT, Adafruit.io and Home Automation - YouTube"

There is an online PDF available, online readable

Information about the connections between SONOFF POW and USB-SERIAL
How to select/activate ESP8266 in the IDE and adjust the correct settings (what I hope, these I found back in other tutorials )
This is the output which I get when I try to upload OTA-mDNS-SPIFFS
