`http://IP-ESP32/wasserzaehler.html`

This is the main purpose of this device. It returns the converted image as a number with different option. The output can be modified either by the configuration parameters or by HTML parameters.

## Picture Server

`http://IP-ESP32/capture`

`http://IP-ESP32/capture_with_flashlight`

This is a implementation of the camera interface of https://github.com/jomjol/water-meter-picture-provider

It is fully compatible including the parameters (`quality`=..., `size=...` ) . This allows to use this ESP32 system in parallel to the corresponding docker system: https://github.com/jomjol/water-meter-system-complete, from which this project is basically the successor.

## File server

Access: `http://IP-ESP32/fileserver/`

Simple file server, that allows viewing, upload, download and deleting of single files of the SD-card content.

The usage is self explaining. The file path or file can directly be accessed by the URL after file server.

Example for `config.ini` : `http://IP-ESP/fileserver/config/config.ini`

## OTA-Update

`http://IP-ESP32/ota?file=firmware.bin`

Here an over the air update can be triggered. The firmware file is expected to be located in the sub directory `/firmware/` and can be uploaded with the file server. By the parameter `file` the name of the firmware file needs to be given.

## Reboot

`http://IP-ESP32/reboot`

A reboot with a delay of 5 seconds is initiated, e.g. after firmware update.

ATTENTION: currently this is not working properly - hardware power off is needed instead. Work in progress!

## Simple Web Server

If none of the above URLs are fitting, a very simple web server checks, if there is a fitting file from the sub directory `/html` This can be used for a very simple web server for information or simple web pages.
