LZW31-SN Dimmer - ZWave Association Group with LZW42 Bulb - ZWave JS UI

I’m trying to set an association group for an Inovelli LZW31 dimmer and an Inovelli LZW42 RGB Bulb using ZWave JS UI. I know I had this working some time ago but at some point I had to factory reset the switch and the group associations were lost. I believe I may have set it up with the Simplicity Studio 5 software back then.

I can set up group associations with other devices no problem, it’s just the RGB bulbs that cannot be added to an association group.

Here is the ZWave JS UI log entry for the unsuccessful assocation.

2023-08-25 22:33:04.768 INFO Z-WAVE: Calling api addAssociations with args: [
  { nodeId: 6, endpoint: 0 },
  2,
  [ { nodeId: 224 }, [length]: 1 ],
  [length]: 3
]
2023-08-25 22:33:04.770 WARN Z-WAVE: [Node 006] Unable to add Node 224 to Group 2 of Node 6
2023-08-25 22:33:04.771 INFO Z-WAVE: Success zwave api call addAssociations false

Here is the log entry when I add a different device succesfully.

2023-08-25 22:34:51.336 INFO Z-WAVE: Calling api getAssociations with args: [ 6, false, [length]: 2 ]
2023-08-25 22:34:51.339 INFO Z-WAVE: Success zwave api call getAssociations [
  { endpoint: 0, groupId: 1, nodeId: 1, targetEndpoint: undefined },
  { endpoint: 0, groupId: 2, nodeId: 2, targetEndpoint: undefined },
  [length]: 2
]

I’ve tried with different bulbs and different switches, no dice. I’ve reinterviewed all the devices. These bulbs will not associate to a group. Nothing in the ZWave integration log, nothing in the Hass debug log. Just the ZWave JS UI entries above.

Anybody have any idea what the issue is here?

Make sure the devices are using the same security level. If the bulb has no security, the switch must also have no security. This is true at least for many devices.

D’oh! That was it. And now that you mention it I think I had the same issue previously. Would be nice if maybe there was a warning in the ZWave JS UI during the association process.

Anyway, thank you so much. This was driving me nuts!
