Invert cover position

[tobi-bo]

Hi,
there was a discussion during WTH of 2020:

WHY THE HECK can't we freely configure a Cover to interpret its percentage value as "percentage open" or "percentage closed"?

UPDATE: This WTH triggered a heated discussion about the logical and intuitive interpretation of “open” and “closed” for a cover: open = 100%, closed = 0% open = 0%, closed = 100% There are obviously diametric differences in interpretation between different users. The differences may be the result of culture, native language, profession, or even personal taste. In addition they may depend on the actual device that is controlled by the Cover integration (i.e. blinds vs. awnings). So I think …

At this thread there are also some solutions with template entities, which worked for me as well.
