Do you mean something like this:
items managed by UI:
Switch OD_Switch_Lucht "Vijver luchtpomp" <light>
Switch OD_Switch_Water "Vijver waterpomp" <light>
Switch OD_Switch_Uv "Vijver UV licht" <light>
your code goes here
And the definition of the actual switches are like this:
Switch Klik21 "Vijver luchtpomp" <light> (gOD_Switches) { rfxcom=">18522370.5:LIGHTING2.AC:Command" }
Switch Klik22 "Vijver waterpomp" <light> (gOD_Switches) { rfSwitch Klik21 "Vijver luchtpomp" <light> (gOD_Switches) { rfxcom=">18522370.5:LIGHTING2.AC:Command" }
Switch Klik23 "Vijver UV licht" <light> (gOD_Swithces) { rfxcom=">16979794.1:LIGHTING2.AC:Command" }
Then in one of my rules, I use this for setting the actual switches to the status specified by the UI:
Klik21.sendCommand(OD_Switch_Lucht.state)
Klik22.sendCommand(OD_Switch_Water.state)
Klik23.sendCommand(OD_Switch_Uv.state)
And this for turning them all off in one hit:
gOD_Switches.sendCommand(OFF)
