Switch RGBW on/off using S2 of Dimmer 2 by association

[jdb 0]

Hi everyone,

 

I have a few Dimmer 2s (FGD212) and an RGBW (FGRGBWM-441).

 

One Dimmer 2 is wired up (3-wire install) to a double switch. S1 controls the wired light. S2 is also connected. The dimmer works from my app for the single light just fine.

 

If I set S2 to control another Dimmer 2 via association group 4, it works perfectly.

 

If I try to set S2 to control the RGBW via association group 4 or 5, nothing happens.

 

Has anybody achieved this? If so, what am I missing? I'm very grateful for any help the community can provide.

 

I am using a Samsung SmartThings hub, not HCL. I will ask the question in their forum too.

 

Thanks for your time.

 

JDB

For me it worked with single-channel association ("S" checkbox), didn't work for multi-channel ("M")
