Documentation suggestion: When I look at z-wave documentation, I see info on repairing z-wave, but nothing on what the first step should actually be when in trouble, which seems to be: shut down hub, power off for several minutes, plug back in.
I ended up going through a few unnecessary steps figuring out what was going on with my formerly well-behaved z-wave mesh, when I finally found on the discussions lots of comments about shutting down the hub. Info like this in the documentation could help some people.
This document has also now been linked to from the one you linked to above (which I believe -- it pre-dates me -- exists as something to collect all the documentation required for certification, which are not always things normal end users may find useful -- but should be up-to-date as well, and maybe this link will help).
