@admin thank you very much for the explaination. Today I have done the installation like you wrote. What should I say - it worked straight away :-)

But I still have two question:

1) I installed it with that code instead of the LAN-Code:

Code:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Esphome-Web-*****"
    password: "***********"

When I want to switch to a connection via LAN, am I right that I have to replace the above code by this one?

Code:

# Example configuration entry
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0

  # Optional manual IP
  manual_ip:
    static_ip: 192.168.1.198
    gateway: 192.168.1.1
    subnet: 255.255.255.0

2) If I decide to leave the connection via Wifi, is it also possible to set a static IP? Can I eventually copy "manual ip" part from the LAN-code to the Wifi-code?

Thank you in advance!
