Hi,
I understand you want a program that goes to "off" your "porte garage" after 1 second.
So you don't need to associate in the device configuration to your macro.
You need something like this in C# :
* Startup code :
Program.Run();
* Program code (Code du Programme) :
Modules.InDomain("HomeAutomation.ZWave").WithAddress("14").Get().Command("MultiInstance.Set").Execute("Switch.Binary/1/0");
Program.RaiseEvent( Modules.InDomain("HomeAutomation.ZWave").WithAddress("14.1").Get();, "Status.Level", "0", "ZWaveNode");
But i am not sure this method is the good way ... Did you try to configure parameter on FGS-212 to change it behavior ?
