Wake-on-LAN Automation: Powering Servers On and Off with Home Assistant

I have a beefy machine in the cupboard that exists to do exactly one thing: transcode media and crunch the occasional batch job. It pulls something like 90 watts at idle, which over a year is a meaningful slice of the electricity bill for a box that’s genuinely busy maybe two hours a day. For ages I left it running because the alternative — getting up and pressing the power button when I wanted to watch something — was worse. Then I wired it into Home Assistant, and now it sleeps until it’s needed and shuts itself down when it’s idle. The savings paid for the effort in a couple of months.
