It might be that these aren’t exposed to scripts yet. @jhonny.goransson ?

Yes there are no exposed properties yet because of technical reasons. People are on vacation right now and we need to discuss this before committing anything. Unfortunately it’s a bit more complicated than to “just expose properties” I’m afraid :slight_smile: but we’ll look at it once everyone is working again.
