Since my script is supposed to return information to the user, I store the information in html format in an attribute of a sensor.
I display this with lovelace-html-card.
Not elegant but it works.

Is there an elegant solution to display information generated by the script?
Can pyscript somehow create components itself that can be used in lovelance?
Is there an option to create UI/dashboard planned?
How did you use the user interaction?

Thanks
