ESP32 OTA connection refused Error 111

ESPHome
1

Hello there,
I have some troubles flashing my ESP32 with OTA. I configured ESP32 for OTA with Arduino IDE. Now it is possible to flash ESP32 with Arduino IDE, but when I try to flash it with ESPhome I got the following error mesage. I’m quite new to ESP and could not find any existing topics here. Does somebody has a hint for me?

Thanks a lot Fabian

Its one or the other. Either use ESPHome or your own sketch with Arduino.
If you want to use ESPHome you will have use an USB and a https connection or use the manual install that will direct you to the web installer or offline tool.

Thanks Charles,
I thought when enabling OTA for ESP32 with arduinoOTA Library it works generally, also with ESPhome…thanks for clarifying…

Np, to clairify:
ESPHome has its own OTA so once its programmed the device can be updated and changed via the Wifi.
It even has a fallback hotspot so you connect to it whenever it falls of the normal Wifi for any reason

This may be a stupid question, but can someone list the exact procedure for OTA update of the firmware?
