I don’t know what makes the difference, but on my KLF200 the WIFI password did not work, I had to use velux123, which took me some time to find out I have not changed any passwords on the KLF200. So the documentation should probably state to try both, since apparently it depends on HW revision.
I think this should be somehow configurable, because although it seems confusing with the window it makes sense when considering we are controlling a “rollershutter” item (the icon shows the rollershutter fully closed when at 100%, and fully open when at 0%).
I also have a couple of MML awning blinds, which show 100% when the blinds are closed and 0% when they are open. That seems logical for awning blinds (and probably some other items).
Also, for the windows, there is the “ventilation” position, where the window is closed, but you still get some fresh air. Does this map to a special setting on the item? I guess if the position status scale is reversed so 0% is closed and 100% is fully open, then 1% would make some sense for the ventilation position?
