LZW31-SN association for virtual 3-way dimming (zwavejs2mqtt 5.10.1)?

I was hoping someone could point me in the correct direction for doing virtual 3-way dimming association with LZW31-SN and zwavejs2mqtt 5.10.1. I see a lot of discussion of setting Parameter 12 to 11, but the newest zwavejs2mqtt seems to have broken Parameter 12 into 4 different toggles. See the below screenshots.

Also, which groups should I create associations for? I have one dimmer wired to the lights, and a second just wired to power with no load. Do I just need Group 3, or do I also need Group 4? Do I need to create the association on a particular switch (the load switch vs the virtual/aux switch)?

This is how it looks in Home Assistant 2021.10.6:

And this is how it looks in zwavejs2mqtt:

All help appreciated,

Load switch gets a value of 15 (all selected). No load gets a value of 11 (all but z-wave hub)

Edit: Groups 2,3, and 4 in both directions.

Change the zwave hub one.

Ah, refreshing the values, converting 11 to binary (0b1011), and it makes sense. Bit 3 (112-0-12-4) needs to be unset, and that is Association Behavior: Z-Wave Hub. Mystery solved, thank you!

Last question for now. When you say in both directions, does that mean create the group association on both switches in zwavejs2mqtt?

Now I just need to get all my dimmers upgraded to the newest firmware, but that is a tale of woe for another time.

Load to non load associations. Set groups 2/3/4.

Non load to load associations. Set groups 2/3/4.

Total of 6 in all.

Got it, thank you!
