On older versions of the binding, I recall having unrespnsive nodes and an OH restart cleared them up… at least for a while.
IMO, it’s more stable than release. When you hit a bad build (like today, I found 1310 badly broke JSR223), just delete it and restore your backup. Very easy to to with a manual install, because it is just one directory.
I think this post has the details you need. But you probably don’t want to go too bleeding edge with the zsmartsystems stuff (I’m still on 1.0.13).
