OK. Is there a way to display all associations of all nodes in the network? It looks like like I need to know the exact association I want to cancel, not just "cancel every association related to node X".
Question 2, kind of basic I fear: how is the mesh laid out (i.e., designed) when I use SUC/SIS? I have a feeling the network is not as good as it could be. Any way to tune it or is it fully automagical?
I don't understand the first question.. but you can display the associations of a group when omitting the node id parameter, e.g. just sending a set association to node x, association group y, and then leave the node list empty. It will then print out the associations in the z-wave device log (when level 36 is enabled).
Regarding the second question, the best way to get a reliable network is to include the nodes in a smart order. E.g. start with routing slaves close to the dongle. After that add routing slaves that are further apart. After that add routing slaves in problematic locations (e.g. plenty of metal around the rocker box, locations very far off, etc.). After that add non-routing slaves. In theory, nodes should fetch the latest network info from the SUC/SIS. In reality not all nodes do so. If you follow this recommendation you should get a solid network. Btw, *never* move routing slave nodes around while they're included.
Where does your "feeling" come from? Do you encounter specific issues?
