Hi,
Your solution of removing items, got me thinking.
I removed one by one the group items by clicking on change and removing the direct group members and then remove the group item. Every time i removed one group item, i checked the model and suddenly when i removed the my Home group item (highest in hierarchy) I got my model back. Do not ask me why Home group items was “corrupt”, but I am glad i got my model back and can configure my OH3 again.
Thanks for your tip. Maybe we should have a model consistency check to find errors in the model file.
Patrick
