I’m about to merge a significant change into the ZWave binding. This will consolidate the various association command classes such that they all provide their information into a single association structure. The main purpose of this is to add support for the multi instance association command class which maps over the old single instance class.
As this changes the XML structure, it will mean that all devices will go through the full query, so you will likely see an error in the log stating that the XML format is incorrect - don’t worry about this.
If you find any problems with associations, please report here. If you don’t want this change yet, I suggest you don’t update the ZWave binding for a few days
