Hello,
I report this example of Massimo

.things
Thing bus_cenplus_scenario_control LR_scenario "Scenario " @ "Scena" [ where="21", buttons="1,2,4,5" ]
.items
String iLR_scenario_btn1 "Scenario Button 1" <network> { channel="openwebnet:bus_cenplus_scenario_control:mybridge:LR_scenario:button_1" }
.sitemap
Switch item=iLR_scenario_btn1 label="Scenario (btn1)[]" mappings=[PRESSED="Scenario-1 (PRESSED)", PRESSED_EXT="Scenario-2 (PRESSED_EXT)", RELEASED_EXT="Scenario-2 (RELEASED_EXT)"]
clicking on the buttons as in the animation are sent on the BUS of the virtual command CEN / CEN + equivalent to short pressure (PRESSED) or long press / release (PRESSED_EXT / RELEASED_EXT) of the scenario buttons.
