Unable to initialize new things from Z-way

[FredrikKarlssonSpeech]

This may be due to me running a pre-relaease of Z-way (2.3.8rc5) in order to fix an issue that I had with my network in the officially released version, but here goes.

I started creating things in OH before from Z-way devices so I know that it did work. Now, however I get this:

/var/log/openhab2/events.log:

2018-07-31 08:49:09.457 [me.event.InboxRemovedEvent] - Discovery Result with UID 'zway:zwayDevice:10_0_1_100:147' has been removed.

no matter which device from the Paper UI inbox I try to initialize as a Thing.
And in the /var/log/openhab2/openhab.log I get

2018-07-31 08:38:59.531 [INFO ] [nding.zway.handler.ZWayBridgeHandler] - Z-Way bridge successfully authenticated

which may be related.

I am running OH version 2.3.0. I actually set up devices previously using non-simple linking, and it worked then. Now, I can get neither to work.

An update to this issue. I may have managed to get around the issue by completely emptying the OH things / items database (moved the jsondb directory), uninstalling both the z-way binding and the openhab connector and then reinstalling them both again in reverse order. Hostname set to localhost in both the connector and the Z-way server thing.

Now, with no simple linking I can again get Items configured for a Z-wave device. At least some of the time. Some devices (Qubino roller shutters mainly as far as I can tell) will fail, although they are working well in Z-way.

Not sure if this is helpful at all.
