For some reason I ran into the same problem when I said, "Alexa, tell Trigger CMD to open movies". Alexa identified "movies" as the name of a computer for some reason.

This phrase worked better: "Alexa, ask Trigger CMD to run movies"

I'll see if I can "train" Alexa to understand the previous phrase better.

EDIT: I see I never implemented "to open" with Alexa. I'll look into adding that, but you can only use these for now:

to run to trigger run trigger

EDIT 2: There's something strange about how Alexa handles the word movies, so I'd avoid using it as a voice trigger for your command. I've been trying to tell Alexa to recognize movies as a command and she just won't.
