The only time I’ve seen something similar is when I had a device showing up twice in ST - one with an Edge driver and the other with a DTH. In that case, both instances could control the device, but status updates were only reaching the DTH version. I would suggest excluding the device, making sure that the device actually gets reset in the process (recently when I’ve deleted z-wave devices, the app processes the deletion very quickly without actually resetting the physical device). Then start over with a fresh include. If you’re still having issues then I’d suggest setting up the CLI to pull logs, though if the z-wave commands aren’t being routed to this driver then they may not show anything useful.
The CLI is the only official route right now. There are also a couple of community-created browser-based solutions - here or here.
