This ESP8266 Firmware is developed to run on the ESP8266 230V I/O Modul developed by luani.
You can find luanis project page here: https://luani.de/projekte/esp8266-hvio

The Webserver of this Firmware is based on FSBrowserNG by Germán Martín: https://github.com/gmag11/FSBrowserNG

For now the language of the Webserver is German.

• 230V-WLAN-IO-Modul
  • Functions
  • Installation using precompiled binaries
  • First Configuration
  • MQTT Configuration
  • Input and Output Configuration
  • Setup your own firmware update server
  • Using the sourcecode
    • Dependencies

• Configurable via built-in asynchronous Webserver
  • built-in SPIFFS file editor, so you can edit all html, css, js,... files online!
• NTP Time synchronisation
• Full asynchronous MQTT support
  • publish output state
  • publish input changes
  • subscribe to topic to control outputs
  • select qos and retain for each publish or subscribe separately
• Automatic Firmware Update
  • MQTT update trigger topic configurable
• Configurable input-output-dependencies
• Config is stored on SPIFFS

1. Download nodemcu-flasher *.exe file
2. Download latest release
   • use ESP_230V_IO_UP_2O.bin and ESP_230V_IO_UP_2O_SPIFFS.bin for the ESP8266 230V I/O Modul by luani
3. Open nodemcu-flasher
4. Connect your ESP and bring it in flash mode
5. Configure Nodemcu Firmware Programmer:
   Try to use lower Baudrates if flashing fails.
6. Select binaries downloaded in Step 2 and don't forget to tick the two boxes!:
   
7. Select COM-Port and press Flash:
   
8. Thats it! Restart ESP and try to connect to it's WiFi Hotspot!

After flashing the firmware the module should appear as a WiFi Acces Point (AP-Mode).

• Name of Acces Point: ESP...
• Connect to it
• Open http://192.168.4.1 in your Webbrowser. It should look like this:
  
• Go to ADMINMENÜ -> NETZWERKEINSTELLUNGEN:
  
• Set your WiFi & Network Config here and press SPEICHERN:
  
• Press Neustart to restart the ESP
• Now the ESP tries to connect to your WiFi network, it will no longer be available as a AP!
• If the ESP fails connecting to the WiFi network, it will open a AP again after about 30 seconds.
• After another 30 seconds the ESP tries to connect to the WiFi network again (if no client is connected to the AP).
• After a WiFi connection is established the ESP will never go to AP mode again even when it has lost connection. You need to restart it manually (Power off, Power on) to get it in AP Mode again.
