Hi everyone,

Since Homey doesn’t support true Z-Wave multicast, I wanted to work around this by using a Fibaro Double Smart Module.

The idea: let the module act as if its S1 input was triggered by a click, which should then activate Association Group 2 and control multiple other nodes at once.

Here’s my current setup.

Unfortunately, this doesn’t seem to work as expected — the associated nodes don’t respond when I try to simulate the S1 action via Homey.

The goal: I’d like to control multiple Z-Wave devices (e.g. several lights) at exactly the same time, without the slight delays you get when Homey sends unicast commands one by one. Essentially, I’m looking for a way to replicate multicast behavior.

Has anyone tried this before or knows:

- Why this approach isn’t working?

- Whether there’s another way to trigger Group 2 associations directly from Homey?

- Or alternative suggestions for achieving multicast-like behavior on Homey?

Thanks in advance!
