Just a note: @Mariano_Colmenarejo has an edge driver called the Z wave configuration tool that works in a very similar way to the old groovy Z wave Tweaker. Regardless of the edge driver you use for everyday use, you can temporarily assign any Z wave device to the Z wave configuration tool, then set the associations, then switch back to your everyday driver.
So if the edge driver you end up with for every day use does not itself expose the association groups, you can use the configuration tool to do that step:

Also, This won’t apply to the device you’re currently discussing, which is mains powered, but be aware that any batterypowered zwave device may only update its configuration parameters once or twice a day. So you won’t necessarily see an instant update. See the following community FAQ for more information about this issue if you are interested.
