Package: pygazpar
PyGazparPyGazpar is a Python library for getting natural gas consumption from GrDF French provider.Their natural gas meter is called Gazpar. It is wireless and transmit the gas consumption once per day.All consumption data is available on the client account at GrDF Web Site (https://monespace.grdf.fr).PyGazpar automatically goes through the Web Site and download the consumption data, and make it available in a Python structure.InstallationRequirementsPyGazpar does not require Selenium and corresponding geckodriver to work.With the new GrDF web site, it is possible to load the consumption data far easily than before.Create your virtual environment$cd/path/to/my_project_folder/

and this project adheres toSemantic Versioning.1.2.0- 2022-12-16Changed#59: [Feature] Support both Excel and Json data source format from GrDF site.#60: [Feature] Permit to load data at multiple frequencies with one method call.Fixed#47: [Bug] No temperature field available.#58: [Issue] No data update - GrDF web site is half broken - Download button does not work anymore.1.1.6- 2022-11-16Fixed#55: Problème de connexion.1.1.5- 2022-07-11Fixed#49: Authentication failure.1.1.4- 2022-01-18Changed#43: Downloaded Excel file name has changed from Donnees_informatives_PCE_$dateDebut_$dateFin.xlsx to Donnees_informatives_$numeroPCE_$dateDebut_$dateFin.xlsx.1.1.2- 2022-01-08Fixed#39: NameError: name 'Frequency' is not defined (thanksnicolas-r).Numéro PCE pas forcément un nombre: Le numéro PCE de mon compteur commence par un 0 et lorsque j'essaie de récupérer mes relevés avec PyGazpar, une erreur de l'API est renvoyée. Le numéro PCE ne doit donc pas être converti en int lorsque il est passé en paramètre mais doit être une string (thanksmaelgangloff).1.1.1- 2021-12-02ChangedExact same version as 1.1.0 except that 1.1.0 has not been published on Pypi repository.1.1.0- 2021-12-02ChangedRemove Selenium usage and use simple Web request for login and data retrieval.1.0.2- 2021-11-25FixedFix broken command line pygazpar caused by adding the new lastNDays parameter.Fix the error : ValueError: could not convert string to float: 'Index de début de période (m3)'. It occurs because the records in the Excel file now starts at line 10 instead of line 8 before (thanks toDEFAYArnaudfor having spotted the issue and bringing the fix).ChangedIn the Excel file, if a cell is empty, then no corresponding key will be inserted in the result dictionary (before we inserted a key with an empty string).1.0.1- 2021-11-24FixedFix typo warning from Pylance preventing 1.0.0 to be published.1.0.0- 2021-11-24AddedNew lastNDays parameter to query data only over the last N days period.Fixed#18: PyGazpar broken since GRDF Monespace has been upgraded to a new version.0.2.0- 2021-04-21Added#12: Be able to retrieve consumption not only on a daily basis, but weekly and monthly:API : Add a new parameter 'meterReadingFrequency' to Client that accepts enumeration: Frequency.DAILY, Frequency.WEEKLY or Frequency.MONTHLY.Command line : Add a new argument '--frequency' that accepts values : DAILY, WEEKLY or MONTHLY.Be able to test using offline data :API : Add a new parameter 'testMode' to Clients used to specify whether we want to get some live data (testMode=False) and static testing data (testMode=True).Command line : Add a new argument '--testMode' (True if specified and False by default).ChangedSome ouput energy property names have changed:'date' => 'time_period'.'converter_factor' => 'converter_factor_kwh/m3'.'local_temperature' => 'temperature_degC'.0.1.27- 2021-04-20Fixed#10: Does not download data file in tmpdir as expected (instead it is downloaded in the default user Download directory). The previous attempt in version 0.1.26 is a failure. The origin of the bug is that we send a relative tmp directory path to Webdriver. Additionally, this path has to be normalized to the runtime OS (using slash or backslash).0.1.26- 2021-04-18Fixed#10: Does not download data file in tmpdir as expected (instead it is downloaded in the default user Download directory).AddedA new parameter to drive whether we want Selenium in headless mode or not (mainly for troubleshooting purpose).0.1.25- 2021-04-15FixedRemove useless warning log messages (log message level has been decreased to debug).0.1.24- 2021-04-14AddedREADME.md amendment (thanks to pbranly).0.1.23- 2021-04-09ChangedFinal release with CI/CD workflow improvement.0.1.22- 2021-04-09ChangedImprove CI/CD workflow.0.1.21- 2021-04-07ChangedCleanup some codes managing Privacy Conditions popup.0.1.20- 2021-04-07ChangedClose an eventual Privacy Conditions popup just before clicking the daily button (instead of Cookie banner).0.1.19- 2021-04-06AddedClose an eventual Cookie popup just before clicking the daily button.Add log messages and screenshot capture around click() and send_keys() methods.0.1.18- 2021-04-05FixedTypo in logger usage.0.1.17- 2021-04-05FixedLogger name must be different in each instance. Usingnameis a good practice, we can get the module hierarchy.0.1.16- 2021-04-05FixedLogger 'pygazpar' initialization must be done inside the main program and not inside the library.0.1.15- 2021-04-05AddedMany log message to help debugging if GrDF site changes something : pygazpar.logTake a screenshot of the corresponding page where a selenium command fails : error_screenshot.png.0.1.14- 2020-09-23FixedGrDF survey popup has to be closed at the home page.GrDF Assistant popup may hide the Download button. We have to close it.GrDF bottom banner that invite to accept cookies may also hide the Download button. We have to accept it.AddedA new parameter 'lastNRows' to get only the last N most recent records.0.1.13- 2020-06-30FixedGrDF data retrieval from Excel file is not limited to the 1000 first rows any more.0.1.12- 2020-06-30FixedThe previous 0.1.11 is not sufficient. Hence, 2 new changes : First, make configurable the waiting time so the user can adapt to its context usage.
Second, the condition on clicking on Download button is now based on the corresponding event and not anymore on its identifier.0.1.11- 2020-06-29FixedWhen GrDF Web site is slower than usual, the client may not wait enough time for pages to load and miss to reach the data file.
It occurs with the page containing 'Jour' button which is very long to load (I increase the wait to load time from 5s to 30s).0.1.10- 2020-06-03FixedExtract rows from Excel until line 1000 (instead of 365 as before).0.1.9- 2019-08-31FixedWebDriver window size must be large enough to display all clickable components.0.1.8- 2019-08-31ChangedUse PropertyNameEnum type to store all property names.0.1.7- 2019-08-29AddedAdd wait_time option to control how much time the library has to wait for Web page element to load (seehttps://selenium-python.readthedocs.io/waits.htmlfor details).Add LoginError exception raised when PyGazpar is unable to sign in the GrDF Web site with the given username/password.Refactor all data property names.0.1.6- 2019-08-26AddedAdd README.md and CHANGELOG.md.Add Client.data() method to get the updated data.RemovedRemove Client.data property to get the updated data.
