I’m in the process of getting my Home Assistant environment up and running, and decided to run a test: it turns out that my gaming PC (custom 5800X3D/7900XTX build) uses more power just sitting idle, than both of my storage freezers combined.
Background: In addition to some other things, I bought two “Eightree” brand Zigbee-compatible plugs to see how they fare. One is monitoring the power usage of both freezers on a power strip (don’t worry, it’s a heavy duty strip meant for this), and the other is measuring the usage of my entire desktop setup (including monitors and the HA server itself, a Lenovo M710q).
After monitoring these for a couple days, I decided that I will shut off my PC unless I’m actively using it. It’s not a server, but it does have WOL capability, so if I absolutely need to get into it remotely, it won’t be an issue.
Pretty fascinating stuff, and now my wife is completely on board as well; she wants to put a plug on her iMac to see what it draws, as she uses it to hold her cross-stitch files and other things.
I had a similar revelation. Home assistant has a WOL component, so you can set that up for easy starts. I’ve had mixed success with mechanisms to get HA to sleep the computer, though.
Ideally I want the machine to be sleeping I’d I’m not using it.
I use Kasm for remote access, I believe that has a WOL component as well. I haven’t set it up as such, but I plan to later on.
If you get a reliable way to sleep a windows machine via MQTT (not sure if that’s a route you’d take) but I’d be super interested in hearing about it.
That’d be interesting, but I don’t plan to integrate my PC that deeply into HA, if at all.
