Virtual Shutter that controls real shutters

[theone]

Hello,

I am new to Domoticz and would like to create a virtual/dummy Shutter Device that controls real shutter devices.

I want the real shutters to follow the state of the virtual shutter: ON/OFF/Percentage.

I managed to create a dummy shutter device using dummy hardware option.

How do I go about controlling the shutters using the dummy shutter? Blockly? LUA?
Or am I in the wrong direction?

What is controlling the shutter and what protocol/command does support?
