Remotely start computer without WoL

Hardware
1

Hello,
I have PC computer without Wake On Lan function, but I need to have option to remotely run computer. The best option for me would have button/card/etc on panel in Home Assistant where I have option to see is computer running with option to turn on or turn off computer. If no from HA, maybe only from Linux CLI, I have HA on Docker on Debian.

I can check is computer running for example with ping. I can turn off computer via ssh and shutdown. But I don’t have any idea how to turn on… My motherboard model is: GA-B75M-D3V (rev. 1.0) Overview | Motherboard - GIGABYTE Global Can I connect some module (or something) inside PC to remotely trigger start? Something to send same signal as from normal button on case? I don’t have any idea.

You could get something like this “key fob” and hack it into HA one way or another but I personally don’t have the hardware to try or explain how.

Failing that a 3rd party NIC which supports WoL but won’t turn ON the PC per se but will allow it to be woken from sleep.

Alternatively, some form of a switch to physically press the button. Depends on how badly you want the functionality.

Would be very surprising that the board wouldn’t have wake-on-lan

You could try setting your BIOS to power on after a power outage and then use a smart plug to control power.

My son’s computer does not support WOL too. I added this:

Or you can use a switchbot to imitate physical button click.

Thanks for answers! Proposition from @koying sounds very good, but probably it doesn’t work. I enabled “PXE boot ROM” option in BIOS and no result. So I tried to enable option in OS:

sudo ethtool --change eth0 wol g
Cannot set new wake-on-lan settings: Operation not supported
not setting wol

What does it mean? I can’t use WoL with this motherboard? I have Ubuntu on that PC, I should install something additional?

I stumbled across this yesterday and promptly ordered some Mini D1’s which arrived today. Going to get to work on testing it out.

I’ll be stripping out the code for the DHT sensor as I’ve no need for that.

Hi, mine doesn’t support WOL as well.
Problem is, the board I’m using is the one for running Home assistant,
It’s an AIO and I’m also using it as dashboard with debian gnome + HA vm under proxmox.
I bought this adapter and I’m not sure how to wake the machine after outage since nothing else can call the wake up command, any ideas?

I have built such a device, and currently Crowd Supply has accepted this project.

I keep a built log in this forum.

I am currently gathering emails from potential buyers.
We are halfway there. So if you are interested go ahead:
