Thank you for this great integration! I am eager to try it out with my outdoor (horizontal) awning, but I have some doubts in what the various parameters mean. For instance windows height is described as:

Height of the window when fully extended

Is it a typo? What does it mean for the window to be fully extended?

Describe the solution you'd like

Does it perhaps mean the distance from the floor to the bottom part of the window?

Describe alternatives you've considered

Maybe adding a simple diagram to the README might help avoid clear any doubts.

Additional context

I have tried to draw a (very basic) sketch to explain my target setup. Are the labels indicated in the drawing correct?
