New C-7 Z-Wave Commands - What do they do?

I really love all the new Z-Wave options available with the C-7 hub, but it's not always clear what each of them do. Any chance someone could clarify them?

I'll start with what I think they mean...

OK : All is good. Nothing to worry about
FAILED: The node cannot be reached
NOT_RESPONDING: Not sure how this is different from FAILED...?

image : Press to update the device's status - To be sure it is really OK, or to find/fixed a Failed node.
image : Press to update the device's route to the Hub
image : Press to remove a Failed device. Usually needs to be done multiple times before it works.
image : I would think that this puts the Z-Wave in Discovery mode and if a device is found, it assigns the current node to it... But I tried this and it didn't seem to work...

Some of this was brought up recently.

This is a comprehensive document that was required for certification:

This is awesome! Some great reading! I learned a bunch of things that I didn't know.

Did I correctly understand that you can pair a Hubitat hub as a secondary controller? If I understand how this works, couldn't you have several controllers and they would all see and control the same list of devices? I use to do this between two older Z-Wave hubs that I had a while back and it worked well enough, though they were not always fully in synch...

There would probably be some problems doing this from a C-7 to a C-5 though, since the C-5 can't do S2... Right?

All certified hubs must be able to join the Z-Wave network as a secondary controller and receive network information from the primary controller. This is required.

Didn't know that the hub could do this. How would you put the HE hub in pairing mode to pair w/another hub?

Right? Me either! I think this is something a lot of us could use... I wonder though what it would do if one setup a C-5 as a secondary master to a C-7... Would S2 devices work... on the C-5?

The instructions are in here:

  1. Start by enabling Z-Wave Inclusion to add devices to the network of the Z-Wave primary controller.
  2. Using the Hubitat Elevation® mobile app, navigate to the Settings and press the Z-Wave Options button.

  1. Tap the Learn Mode button, then Start Learn Mode .

NOTE: If the hub has any nodes joined to it, then it cannot receive network information from the primary controller. To allow the hub to join as a secondary controller, you must first exclude all joined Z-Wave devices.

  1. The primary controller should indicate a device has joined its Z-Wave network.
  2. When successfully added, network information from the primary controller will be replicated on the Hubitat Elevation® hub.
