I run RedMatic (7.2.0) on a CCU3.
If I select the packae to install RedMatic-homeKit (3.2.2), I get an error message. "Es ist ein Fehler aufgetreten"
What I see is, that the url for the package in the list is undefined.
I also used RedMatic (7.1.3) and got the same error.
All the other packages are installable.
