@Rodney-Mathee, I'm glad you told me it's wifi, not wired ethernet. That changes things. For one, that WakeMeOnLan.exe tool from Nirsoft won't work because it doesn't support wireless networks.

I've never tried "wake-on-wlan" but in theory it's possible with the right hardware.

@Lokilator nice, I've used the shutdown command in the past. I haven't seen that one.

@Pepe-Tops , good to know. I'll test and fix that if I can reproduce it.

@Guilherme-Matos, I tried it. When I ran the TRIGGERcmd Agent in the other user account on my computer, the token prompt did show up, but I had to click the agent's icon at the bottom of the screen because it was behind my browser. I had to bring it to the front.

If you don't get an icon at the bottom, let me know, and please tell me whether you're using the latest version. I'm running version 1.0.56 which I'm about to release. I added an emoji icon picker for commands.

@Matt-Packwood, I thought I did produce an Apple Silicon version. Are you saying this version isn't an Apple Silicon version?

@Jhon-Piñeres
The answer is probably found elsewhere since you asked your question, but because this was the first thread i found i think i post my solution here:

Command for shutting down:
shutdown /s /t 120

I choose 2 Minutes because thats the a longer time i need to leave but so normaly enough time to stop if i forgot something.

Off Command:
shutdown /a

Now i can tell my alexa to shut down my pc, by switching on shutdown, but i have also 2 minutes to cancel the shutdown by telling alexa to turn off shutdown.
