I just noticed I have a ghost/non existent node on my C8. I only noticed it due to @tony.fleisher's Z-wave mesh details tool. In his tool it shows up as a unknown node.
On the Z-wave details page it is only shown as a node that one device is using. There is no node 0xF3. This device is working.
Yes I had a real problem with that when I first moved into this house. There was a spot on the rear of my house that I thought I had a water leak. I couldn't find it. I finally realized it was just so much condensation it appeared I had a slow leak running down the wall. I did a lot of youtube videos and reading. I have encapsulated my crawlspace and the humidity now stays a constant 49 to 50%.
I don't have a C8 yet, so not sure if anything is different there, but based on my experience with C7...
The "Unknown" shows up in the routers table if a router is found for a device but the router device is not in the z-wave details list. If the device is working, it probably is nothing to worry about (unless you are missing a device from the z-wave details page).
You maybe able to get the route updated by a power cycle/wakeup on the end device, or it may fix itself in a couple of days.
Was this z-wave network migrated from a previous hub, or was it built on the C8?
I realized a bit ago that there was a device missing. I am almost certain it was there initially, as it was migrated from a C5 to the C8. All the devices were working. Not sure what happened. I thought maybe that was it. I excluded the device and paired it back up but I still have the F3 node listed.
It was migrated from a C5 as noted above.
I do not, but I wonder if it has something to do with MY C7 that I am trying to decommission as it were. I had two device hubs in the house, a C5 and a C7. I migrated the C5 to the C8 and I am moving everything off of the C7 to the C8.
I just noted the C7 that I am moving devices off of also has a node like this. There are only about 5 Z-wave devices left on the C7. I guess I will wait until I finish and shut down that C7 hub and see what happens.
On the C7 it is node 50. Which at one point there probably was a 50, but now there are only a few Z-wave devices left. Below is the entirety of Z-wave on the C7 now.
