[Edge] Wake-on-LAN via Alexa command

I might be missing something obvious, but I am trying to use this, and I cannot find the device settings, where I should be setting the mac address.

I can install the driver, and vWOL_1 shows up when I scan, but when I tap on the resulting tile (either on my phone, or on the web UI) nothing happens. Normally, I would expect to see the status/settings etc… but nothing opens.

Likewise, I am not sure what you mean by the “SmartThings device Controls screen” if I want to create more WOL devices.

What am I missing?
