@joostlek These are all the things I found that I think they need quality improvements, do you know any tool or command that can help me find any other code quality issues?

We want to remove as much throttles as possible, so it would be interesting to explore the option of adding a coordinator

We want our functions completely typed in general. Instance variables are usually inferred when set (unless mypy complains, then you add one). So we don't have to overwrite every instance variable with a type outside of the constructor

I noticed that in some components, the entity description tuples are placed at the end of the file This might be a good idea to apply because entity descriptions can be quite large, and if they are placed before classes and logic, classes and logic will be be at the end of the file, which means you have to scroll all the way down to get to the code, which is quite inconvenient and sensor. (And also specifying the type of the tuples might not be necessary)
