Z-wave JS - setup failing

I’m trying to setup Z-wave JS (since my migration from 2022.3 to 2022.5 seems to have killed my old Z-wave setup).

My initial attempt to install the integration didn’t complete, as I didn’t have my network key.

Now, however, every time I try to re-add the Z-wave JS integration, it errors with a pop-up saying ‘Failed to connect’.

I assume that it’s got the incomplete config info stored somewhere, but I don’t know how to clear that out and start again.

Any tips?

I never figured out how to get this working. However, having left my Home Assistance setup alone for a year or so (while still using it many times every day), I went ahead and did an update, jumping ahead about 14 versions. I uninstalled Z-wave and reset my devices before updating.

After the update, and setting up Z-wave JS from scratch, everything works perfectly again.
