@Mark-Hollis, do you want to run your command with multiple parameters? Like this?
notepad one twoIf so, do you want to provide those two parameters with your voice? If so, yes, you can provide them via an Alexa routine, but you'll want to use the TRIGGERcmd or TRIGGER command skill instead of the TRIGGERcmd Smart Home skill, and follow this procedure instead:
Open the Alexa app on your phone:
Tap More in the lower right Tap Routines Tap the + in the upper right Tap "Enter routine name" and give it a name Tap "When this happens" then "Voice" and enter the phrase you want to say, then tap Next Tap "Add action" then "Custom" then type: "Ask TRIGGERcmd to run notepad with parameter one two"
