Diagnosis of z-wave nodes

[stuiow]

Some advice please.
I want to weed out any faulty nodes on my z-wave network that maybe affecting the entire networks stabilty.
I will do this by using the OZW control panel stats screen where I should see any nodes with failed receives.
But my concern is that a node with high failure rate may actually be affected by another node (thinking mesh feature).
Anyone any experience on this stats screen?

Also, I have several Fibaro Dimmer 2 relays, but one in particular has cause for concern.
If I remove the z-wave cache file, when the cache file rebuilds, this particular node is always listed as a controller initially, but after a node info request by myself, then changes to a light dimmer switch, but not LBR+, it gives it a FB+.
Should I be concerned with this behaviour?
