First of all naming conventions and naming.
I used that name because the company providing the service of collecting waste is KRAB and in Sweden.
It's an abreviation of "Kristianstad Renhållning AB" or as a weird translation it would be something like "Kristianstad Wastecollection Stock-Company" (or just Company, Ltd).
Depending on the definition of service provider the service provider it maybe should have been more like "api_universal_appbolaget_se" but that's just a url to a REST service on a consultant company and doesn't really define this waste collection.
I looked swiftly at some other implementations there are not a very strict naming convention as some refer to a more generic domain and some takes the name from a minicipality site not specific to waste collection.
But the name can of course be changed if that is critical.

I'm sorry for the code as it's really so many things that's wrong there. There's no other way of sayng it than it's totally FU.
It's a weird mix of what's running on my Home Assistant and some early mockup making it even worse than the mockup.
I'll be back with a working code.

Thanks for your contribution
