12 volt Z wave switch to turn on computer

I am looking to find a 12 volt(low power) Z Wave switch that I can splice into my Windows based desktop computer power button to turn on my computer from my iPhone/SmartThings.

Thanks for your input.

I know you are looking for a 12 volt system. But I use this plug and set my computer BIOS to auto reboot. That way, my computer boots when I tell “Alexa, turn on my computer” and the plug is turned on. Not sure if that will help you if you are committed to a 12 volt answer.

You could just use a Wake On LAN magic packet to turn on your computer. No wiring required.

To be honest, I would prefer the method you mentioned but I could not figure out how the shutdown sequence/turning off the computer with the switch still on would work. Could you please give more more detail on you have set the process and up.

Thanks for the input!

I updated my post with a link to @stephack’s Boot Me Up Scotty App. There is probably more details in that thread. I have not personally implemented this.

@Duce, my process is quite simplistic. The boot time for my computer is several minutes (old hardware). So I “turn on” my computer while making coffee. Then it is fully booted once I get to it. I shut down my computer using the typical Shut Down option from windows and then turn off the plug. Sometimes I do turn off the plug while my system is running but I don’t have vital software running at that time. So no real magic for the shut down.

Are you aware of a way for the computer to send a signal to the switch, (through SmartThings hub) to turn it off after the computer has turned itself of without you doing it manually?

Lord, give me coffee to change the things I can change, and wine to accept the things I cannot.

Good question. I’ll have to look into that.

Here ya go. You don’t need all of it but the info is there.
