Switches/Dimmers and accessory switches WITH associations?

I wonder which devices are there available on the US market that support the double-tap or triple-tap functionality to control additional groups.
I have Linear WD500Z-1 dimmers; contrary to manual (which says they support 3 groups) it does not support any.
Further, I have Linear WT00Z-1 accessory switches; they support only 1 group (and not 4 as stated).
Finally, I just got ACT ZTW103 accessory switches, and these also support only 1 group despite an ACT rep saying they support 4.
So far, this testing has been rather expensive yet grouping is a required feature for me.
So, if anyone can confirm that a currently available ZWave product supports double- or triple-tap to control several groups, I’d be grateful to hear.
Best,
Jonas

Kinda digging up a moderately older post here, but I am going down this route too and don’t want to pull the trigger buying up a bunch of switches if they aren’t going to work as advertised.

I see that there is a page on the Linear website that says you need to use a Aeon Labs Mini-mote for associations. Have you tried that approach?

I also want to know if they possess the capability of controlling my yet-to-be-purchases micro dimmers. If they don’t, I need to rethink my set-up.

I am still in build mode with my system and I, like you, don’t want to purchase a bunch of equipment that isn’t going to work the way it is intended. Hopefully there’s some insight out there.
