VM or container? VM is easier and can be usually configured even via Proxmox GUI (Hardware - Add PCI). Various OSes need various levels of effort. Some Linux distros don’t need any more config, Windows on the other hand required a custom GPU ROM on my system to work.
This can be done even with a single GPU, even the built in iGPU.
Absolutely wrong. I have dozens of devices integrated, from a lot of brands, all working. You can of course try to get a turnkey solution from like Loxone, but be prepared to pay thousands of dollars, and good luck adding anything that’s not in their ecosystem. And there’s a lot of that. And what is there is all pretty outdated.
Xiaomi is great and I use a lot of their stuff, but the options for automation are severely limited.
I’m in the same boat. I’d like to have something like this integrated with Home assistant but Grocy is just ludicrously complex. It’s like SAS for your fridge, only more complex. With rude developers who always know better than everyone else.
