I cannot find any exemple, so I guess it’s not possible. Apparently, for such case you have to create a script calling the service and then turn on your script from the scene.
So if I create a script, what the point of the scene? Everything can be done in the script.
My case is pretty simple, it’s a good bye scene where I turn off all the lights, close the covers, turn off the tv (harmony remote), and arm the alarm.
