Combine switch with Led RGB (like HUE or Yeelight)

[LaMax]

Hi, it's possible to combine a On Off switch with a RGB command (they are 2 separate device)?
My case is: 1 z-wave switch (fibaro) control the on state of a Yeelight, but i have 2 control for on and off (1 for the fibaro switch and 1 for the Yeelight) and 2 device listed in the panel for a single activity.
It's possible to merge this device? For me it would be useful for controlling the device with my voice (using home bridge) and not have to assign 2 name for the same lamp.

Sorry for my very poor english.
Thanks.
