There are real time network monitoring tools for Z wave available, but smart things has not made them available to customers for their particular platform.
There is one you can buy which is intended for professional installers and some community members have. It’s very cool, but list price is something like $249 and it occasionally goes on sale for $189. More than most people want to spend.
Looks like it’s still on the holiday sale at $149.
