Fibaro Groups / Associations set-up

Hey all,

I am trying to set up Fibaro to Fibaro communications to have less lag in switching lights on and off.

I am trying to do this in the Zwave JS Control Panel, under “Groups”.

I tried to set-up a connection from a Fibaro Walli Switch to control a Fibaro Switch, as you can see in the image below, but it doesn’t do anything…

Any help of pointing me to a manual or providing options how to put this into the Fibaro devices using Home Assistant would be much appreciated!
