Z-Wave also supports device associations which Zigbee doesn't. You can permanently associate devices together (i.e. switches) to create a virtual 3-way switch that will work even if the "smart home hub" is down. Which, from a reliability perspective is a much better design if you're installing something commercially.

Is that not binding in Zigbee?

Home assistant docs because I can't find a better description: https://www.home-assistant.io/integrations/zha/#binding-and-...

I wish Z-wave or something would support some form of physical connection instead of relying on wireless. I'd be perfectly happy running CAT-5 to every damn switch in the house if I could get reliability from it.

I've fallen back to physical switches that can be relay controlled.
