pyveoliaidf 0.2.1

Retrieve water consumption from Veolia Ile-de-France web site (French Water Company)

PyVeoliaIDF

PyVeoliaIDF is a Python library for getting water consumption from Veolia French provider.

Their water meter are wireless and transmit the consumption once per day.

All consumption data is available on the client account at Veolia Web Site (https://espace-client.vedif.eau.veolia.fr).

PyVeoliaIDF automatically go through the Web Site and download the consumption data CSV file, and make it available in a Python structure (list of dictionaries).

Installation

Requirements

PyVeoliaIDF is working with Selenium Python library to automate navigation through Veolia Web site. Selenium requires a WebDriver that acts as gateway between automatic actions from PyVeoliaIDF and a native browser already installed on the system.

PyVeoliaIDF has been developped and tested with Firefox browser (version 68.8) and its corresponding Web Driver geckodriver (version 0.24).

$ cd /path/to/my_project_folder/

$ virtualenv venv

PyVeoliaIDF installation

Use the package manager pip to install PyVeoliaIDF.

pip install pyveoliaidf

You can also download the source code and install it manually.

cd /path/to/pyveoliaidf/
python setup.py install

Usage

Command line

$ pyveoliaidf -u 'your login' -p 'your password' -w 'path/to/Selenium Web Driver' -s 30 -t 'temporary directory where to store CSV file (ex: /tmp)'

Library

import pyveoliaidf

client = pyveoliaidf.Client('your login',
                         'your password',
                         365,
                         'path/to/Selenium Web Driver',
                         30,
                         'temporary directory where to store CSV file (ex: /tmp)')

client.update()

data = client.data()

Output

data =>

  }
]

Limitation

PyVeoliaIDF relies on how Veolia Web Site is built. It goes through each Web pages and automatically fill forms, click buttons using their internal identifiers.

Any change in the Web site structure or identifier naming may break this library.

We expect in close Future that Veolia makes available a standard API from which we can get safely their data.
