I like really OH and i use the stable versions since many years with 100+ z-wave items. The first time with OH was very difficult, but the Forum and Discord helped me a lot.
The problematic part is for me for example the inconsistence of the parts. We have more UIs and we have the possibility to define things programmatically. But the information from this sources are not on the same place. If i define something in the UI and i define in file they should be in the same place, but its not so.
But if u can live with this small problems, than the OH is a very powerful thing.
