Thanks to the person who posted this.

Introduction This guide describes how to switch from the Z-Wave JS official add-on to the Z-Wave JS UI HA Community add-on, without losing any downtime caused by the re-interviewing of nodes.

This guide is for HAOS add-on users who have already installed the official Z-Wave JS add-on and the companion Z-Wave integration, and desire extra functionality that isn’t provided by HA, such as: Adding and remov…

Otherwise to do this in HA you will need to figure out yourself whether you need to create the association with the Association CC or Multi Channel Association CC, choose the correct API based on the CC, and use the zwave_js.invoke_cc_api low-level integration action to perform the association, filling in all the required parameters and values.
