@Russ It was my mistake. I discovered where was wrong Sorry
How to create a trigger to turn off? and is there how to turn on the pi by voice command?

@Russ I wrote this, but appears what I mentioned

What I did wrong? It appears:
E: Unable to locate package https://agents.triggercmd.com
E: Couldn't find any packageb by glob 'https://agents.triggercmd.com'
E: Couldn't find any packageb by regex 'https://agents.triggercmd.com'

I'm a noob, and sorry for my english.
