How to interpret ZWave clusters?

How do I understand the mesh structure from ZWave clusters numbers that HE provides?

I have a problem with Yale lock working very unreliably with HE (worked perfectly fine with ST) and trying to understand whether my GE dimmers indeed act as repeaters..

Besides ruling out battery devices that sleep, the cluster numbers won't help you determine if the device is being used as a repeater.

Almost all wired devices can act as repeaters, but you can't tell if anything is actually being routed through it without a z-wave sniffer.

Thanks @krlaframboise.
Can you please explain the theory behind these cluster numbers?
I googled all I could about it and only found other people looking for the same info.
It would be good to have some small help screen attached to the web page table in order to help people make sense of the presented info.

It's not possible to explain this on a forum...
This may or may not help...

Thanks - this is definitely useful for understanding Z-Wave command classes and their encodings.

Would you have similar link to the specification of Z-Wave routing? Something that mentions the term "cluster"?

Cluster is defined on the zigbee side of the house, however for zwave it's informally used as a synonym for command class.

ah thanks! Now the mystery of the clusters is resolved :slight_smile:
So "in:" are the command classes that device can receive and "out:" for command classes it can emit. Essentially the information that device provides in the "node information frame". Might be good to add a tooltip on top of each hex number that would show decoded name of the supported command class. Will remove terminology confusion and will provide valuable info.

In the same frame, device advertises, whether it's capable of routing and beaming.
It would be really good to provide this information to the hub users, so users know whether their intermediate devices really help them reach further parts of the network/communicate to the battery based devices.

I guess ... Almost every plugin zwave device is a repeater. So I'm not sure why this needs to be in the UI.

If you really want to see about a specific device you can always go look at the Z-Wave conformance report. Only takes a second to look up.

This is basically a summarized version of what Mike posted...
