@marciosenaf, for the TRIGGERcmd Smart Home skill to create devices, your commands need the voice field filled in, and the computer needs the voice field field in unless it's your default computer.
I suspect your first computer was the default computer but your new one is not. If so, you could fix this by setting your new computer as your default computer in your profile.
Click your name in the upper-right, and click Profile, then use the Default Computer pulldown to select your computer.
