Don’t get confused with Item Group and Sitemap Group. This are two completely different things. Item Group will group items logically. Sitemap Groups will just group them for displaying purposes.
But this will not solve your problem. I just saying this in case you didn’t know.
I’m in trouble with Group:Switch also. I already opened an issue.
to be honest it also seems like a bug to me. I’m trying to set the basic things up with the paperUI but I get more and more clues that I cannot do most things with paperUI without running into some bugs…
It doesn’t matter what I change the group rule to, it seems to always be “undefined” if its items are mixed (on and off both available).
From the paperUI it should be the rule “All OFF -> OFF else ON” if I want to have the group ON when any device is on, correct?
To me it seems to be related to the creation with paperUI. When I create the group in the config file it works fine. To bad Maybe that issue gets fixed together with your Markus.
