Computer Power with Wake On LAN

I’ve been wanting to control my PC power from SmartThings for a few days, and after searching and searching with no luck. I finally got around on to playing with Groovy. I figured I’m not the only one who would like this. So here you go a fully working WOL and eventghost SmartApp.

You will need a simulated switch, a PC that is WOL capable, and EventGhost with webserver and shutdown trigger.

I’ve been trying to get this to work, and I cant

I have WOL working from the web (ports 7 & 9 opened from the web through to an address that is reserved on my DHCP server) and have it working internally where I send it to the broadcast range of the network (10.x.x.255) and from my router it works, and from my mobile android device it works… But I cant get this to work.

I have even changed the line of code from “wake on lan $macaddress”, to “wake on xxxxxxxxxxxx”, and put the actual Mac address in the code (ruling out any variable passing line 93) and it still doesn’t work.

I just cant get this new WOL functionality in SmartThings to work on my network :frowning:

Figured it out. I used a Magic Packet snifer and found that even if you didn’t put a secure-on password in, the WOL command would be broadcast with 12 0’s at the end of the WOL packet, which my machines were ignoring.

If you put a secure password in as 123456789123 then all works.

I did a tutorial on this a while back.

hi, where you put the password? Only in the smart app or where else?

Hey, In the App, I believe there is a section for “secureon” password. Must admit, I didn’t stay with this app very long, as it only woke and shutdown the PC. It didn’t remain in sync with the PC (so If I turned on the PC by the button, it didn’t update in the App) I moved to sumitkgarg : WOL Switch.

Ok, thanks… I will search for that app instead. Im new on this. Thanks!

It’s great having a little Pi to serve other things that connect to SmartThings. The sync is easily fixed with Host Pinger which my Pi host. I even use the PC as a motion sensor! It is explained in my tutorial:
