[Follow up] Zigbee & ZWave devices Help
Thank you Nicolas. I have made progress by making devices' "On/Off" switches appear in the Home app, though not what they are named in the Harmony app. For example, what I have labeled "Floor Lamp", is listed as "zwave4" and "Smart Things Outlet 1" is "zigbee0x21B7" That's fine.  However, I can't seem to get the dimmers to show up for the plugs which have them.  I do see the "brightness" function update in HomeBridge when I change it through the Harmony App.  I'm not sure what I'm overlooking.

Here's what I think is the relevant log for my example zwave4

HomeBridge shows the devices, their capabilities, and their state

First I tried:

   {
        "name": "Harmony Hub",
        "hubIP": "192.168...",
        "hubName": "Harmony Hub",
        "publishGeneralMuteSwitch": true,
        "publishGeneralVolumeSlider": true,
        "linkVolumeControlToTV": true,
        "homeControlsToPublishAsAccessoriesSwitch": [
            "zwave3",
            "zwave2",
            "zwave4;on",
            "zwave4;brightness"
        ],
        
        "platform": "HarmonyHubWebSocket"
    },
That made the switch in the home app disappear

  {
    "name": "Harmony Hub",
    "hubIP": "192.168....,
    "hubName": "Harmony Hub",
    "publishGeneralMuteSwitch": true,
    "publishGeneralVolumeSlider": true,
   "linkVolumeControlToTV": true,
    "homeControlsToPublishAsAccessoriesSwitch": [
        "zwave3",
        "zwave2",
       "zwave4"
],
    "devicesToPublishAsAccessoriesSwitch": [
    "zwave4;on",
    "zwave4;brightness"

    ],
    
    "platform": "HarmonyHubWebSocket"
  },

That made the switch come back, but still no dimmer. Also, I made sure the plug is categorized as a light so the Home app will allow for a dimmer, which I think is they way it's supposed to be set up.

What should I be looking to do next?
