ESPHome Application

See Esphome configuration file kostal-piko.yaml for the application

Preparation and creating the application

• Download the esphome config https://download-directory.github.io/?url=https://github.com/zibous/ha-kostal-piko-esp/tree/main/esphome/config

• Extract the zip archive and copy the files and directories to /docker/app/esphome/config

• Start Docker ESPHOME

• Create secrets.yaml based on template_secrets.yaml and adjust the entries

• Create and deploy the application to the connected device with the esphome dashboard application or with ESPHome-Flasher utiltiy.

ESPHome-Flasher

ESPHome-Flasher is a utility app for the ESPHome framework and is designed to make flashing ESPs with ESPHome as simple as possible by:

Having pre-built binaries for most operating systems.
Hiding all non-essential options for flashing. All necessary options for flashing (bootloader, flash mode) are automatically extracted from the binary.

This project was originally intended to be a simple command-line tool, but then I decided that a GUI would be nice. As I don't like writing graphical front end code, the GUI largely is based on the NodeMCU PyFlasher project. Self-contained NodeMCU flasher with GUI based on esptool.py and wxPython

The flashing process is done using the esptool library by espressif. esphome-flasher, a tool to flash ESPs over USB
