 Unlike most KNX devices, Home Assistant defines 0% as closed and 100% as fully open in regards to covers. The corresponding value inversion is done internally by the KNX integration.
 
+Home Assistant will, by default, `close` a cover by moving it in the `DOWN` direction in the KNX nomenclature, and `open` a cover by moving it in the `UP` direction.
