Z-Wave mesh performance

I have questions about the Settings -> Z-Wave Details page.

When I first installed my Zooz switches/Hubitat hub system I had delayed actions to Z-Wave triggers (5+ seconds) that I attributed to the Z-wave network. I have a standard 3 floor single family home, all the wiring is in metal conduit/boxes and some switches have metal wallplates. I added two more hubs (3 networks in total) to give me one hub per floor and that "mostly" cured the issue but I now want to ensure I have the optimum Z-Wave network, maybe replace the metal wall plates so I have questions about the Z-Wave details page.

  • LWR RSSI values appear to be "static", they never change regardless of how many times I hit repair. Furthermore 50% of them are "N/A".

  • Similarly the RTT Avg values do not change and 50% of them are blank.

  • How do I change the routing of a battery device, some of the routes appear to be very wrong?

  • I have seen comments in the posts that the hub does not have a spherical radio field. If it is mounted vertically it produces a stronger field in the horizontal direction. Is this correct and if so is there any difference between the field on the front/back of vertically mounted hub?
