Assuming you want the shades ONLY as context you can still create as many as you want without having to use the HB_EPWindowShades to create the zone. Part of my assumption is that you don’t intend to use blinds in addition to the shades.
The reason the component is "failing’ is because there is a chance of crashing EP simulation. The code is preventing that.
In any case, even when the component generates the shades, they are not used in the IDF file, unless you add them as context.
See attached for a working file. Check the panel from the !readMe output!!
Hope is what you are asking for. If not, keep asking
