A Python library for getting historical and forecasted usage/cost from utilities that use opower.com such as PG&E
A Python library for getting historical and forecasted usage/cost from utilities that use opower.com such as PG&E.
Supported utilities (in alphabetical order):
To add support for a new utility that uses opower JSON API (you can tell if the energy dashboard of your utility makes network requests to opower.com, e.g. pge.opower.com in the network tab of your browser's developer tools) add a file similar to pge.py or pse.py or bge.py etc.
Name the file after the utility website, e.g. pge.py for pge.com.
Since this library is used by Home Assistant, see https://www.home-assistant.io/integrations/opower/, per https://github.com/home-assistant/architecture/blob/master/adr/0004-webscraping.md we cannot have a dependency on a headless browser and we can only parse HTML during login.
An exception is made for the authentication phase. An integration is allowed to extract fields from forms. To make it more robust, data should not be gathered by scraping individual fields but instead scrape all fields at once.
So follow that advice and try to scrape all fields at once, similar to the get_form_action_url_and_hidden_inputs in helpers.py.
