Z-wave JS UI and "correct address for the community add-on "

[knotty gazelle]

I'm having problems with my Z-wave integration - no devices are reachable. My guess is that it started when I wanted to use the Z-wave JS UI addon to get the network graph, but was interrupted in the middle. Now I've tried to follow the instructions on https://www.home-assistant.io/integrations/zwave_js/#how-to-switch-between-z-wave-js-and-z-wave-js-ui.

I've gotten to step 5, where it says "Enter the correct address for the community add-on in the URL field in the next step." The default is ws://localhost:3000 but that results in "Failed to connect". And I guess I shouldn't use ws://core-zwave-js:3000? That is accepted but since the next step is to uninstall the Z-Wave JS addon, it seems odd.

I've also tried entering "localhost" in the (optional) configuration field "server host" under the Z-wave JS UI "Home Assistant" config. It doesn't help, I still get "Failed to connect" when I try ws://localhost:3000 in the Z-wave config.

Please help - all my Z-wave is down! I'm sure the answer is simple, but I can't find it!

Use ws://a0d7b954-zwavejs2mqtt:3000 for the Z-Wave JS UI add-on.

Thanks! How/where should I have found that out?

You won't like my answer.

It is stated in the Z-Wave JS UI add-on documentation.

I could have guessed. A reference to that from the "how to switch between..." would be nice.

Also, how do I switch back? The instruction header is "switch between" but really describes "switch from JS to JS UI"?

You use the same encryption keys, install the old add-on and add the Z-Wave integration with the default settings.
