Group 1 association in a dimmer

Other Devices & Integrations Lighting & Load Control
1

Looking at the Group Association feature of wall mounted dimmers, I see that the “old” ZDW120 supported 4 groups (1-4) and the new ZDW120 supports only groups 2 and 3.

Group 1 support meant you could configure other devices to be co-switched with the local load. (Groups 2 and 3 work remote devices via a double and triple tap respectively.)

Are there any dimmer modules around that still support groups 1-4? Or 1-3, at least?

I determine through trial-and-error that the Intermatic CA600 supports group 1 but not groups 2 or 3.
