Hallo @hmerk having a quick look at the project - great idea by the way - seems to point that the second problem seems to be solved. I can parse through all items of an equipment and even have a great filtering for item types - e.g. seen in Light Card widget
But also here I have to configure the groupItem as the root for the oh-repeater.
What I’m also looking for is a way to get this “groupItem” automatically by a reference to the Item or equipment the widget is linked too.
Can I get this reference somehow?
E.g. in above picture I would like to get the reference to the item HeizungErker_ActualTemperature.
