Now after browsing the forum I see that if you have only one computer running TriggerCMD, you don't have to put in the optional voice command. But if you have more than one, then you have to put that in for Alexa to recognize it.
SO BOTTOM LINE:
If you are running TriggerCMD on only one computer, you don't have to put in the optional Alexa voice command when creating a new trigger.
But if you are running more than one computer with TriggerCMD, then you have to put in the optional Alexa voice command with every new trigger command. Otherwise, Alexa will not recognize it.
