Zwavejs transition from old HA and zwave setup

I’m in the process of trying to switch from ancient early 2020 HA+Zwave to the new Z-Wave JS and latest released 2023.x HA (both in docker) and am impatiently waiting for my gen5 stick and zwavejs to query the 17 door/window sensors and get its brain populated with the pertinent info. Man it’s slow, but it’s progressing. About 4 hours in so far and still 4 devices to go.

I had a question about where to configure things.

I see in Z-Wave JS UI that I can name the detected devices and set their locations in the gui. Cool. Is that the preferred way to define them (in the Z-Wave gui) or is that something I should do in HA (if so , where) instead ?
