@russ I'm also having issues using the reboot and shutdown commands. I've called my PC "computer" and so I've tried to ask Alexa both "Alexa, ask TRIGGERcmd to shutdown computer" and "Alexa, ask TRIGGERcmd to shut down in 1 minute computer".

However, Alexa responds with "Could not find a computer with voice word shutdown in 1 minute." (same issue with rebooting also).
