Side Projects
A python library that helps with checking for driving fines/obligations from the official government website. Since the website is very unstable, this handles most of the ways it can break. The motivation behind creating this is to use it as a base for my own HomeAssistant integration. I’ve split them up so that the library can be used standalone by whoever may need it.
A custom HomeAssistant Community Store (HACS) integration, a wrapper around my Python library which enables the user to automatically check for fines and monitor their state directly in HomeAssistant.
