Thank you. That is the sort of plain English language that helps dummies like me. I have not seen it written like that in the documentation but I wish it was. Sometimes the documentation is written assuming that only experts will need to understand it.
From your response, I now understand that I DO have a Z-wave JS server installed with the URL of ws://core-zwave-js:3000.
I have also installed Z-Wave JS UI and it looks like this. I have also managed to pair (include?) a Z-wave sensor to that controller.
BUT, I cannot see either the controller nor the sensor under devices and entities in HA.
If I need to install a second Z-Wave JS server, how do I know what the URL should be? Apologies, I cannot for the life of me find that in any documentation. It defaults to ws://localhost:3000 but I assume that is incorrect for a second server.
Please point me in the right direction, I have read and read and still none the wiser.
Yes, this is the official add-on. Stick A is being controlled here with one instance of Z-Wave JS, and this add-on provides a Z-Wave JS server. It’s already integrated with HA.
Stick B here is controlled by the second instance of Z-Wave JS, and the ZUI add-on also provides its own Z-Wave JS server. Now you need to integrate it with HA (hence “integration”), it’s not automatic.
If I need to install a second Z-Wave JS server, how do I know what the URL should be?
You already installed the second Z-Wave JS server, it’s provided by the ZUI add-on. The ZUI Add-on docs here, which are also accessible from the add-on page itself, give you step-by-step instructions on how to setup the integration, along with the required server URL.
The HA docs that I also previously linked, and which youliterally quoted, have the same instructions and provide the explicit server URL to use with the ZUI add-on:
That is referring to using two add-ons with the same controller, since they compete for access over a single serial port (hence the “switch between add-ons”). It is not a problem to run them with two different controllers.
