Thank you.
As far as I can see, I can go for the devices listed, as they are supported or about to be supported. According to your suggestion that would make the VIM3 the best option for me. To stay in the HA OS compatible zone (which I’d like, because I’m new to it. Although I could probably manage a supervised install as well), I’d have to choose on of these devices or a x86 device, which will probably bump the cost by quite a bit and is probably not necessary for me (again, for now).
What kind of addons/use-cases would require a lot of RAM? ESPHome is likely to be used as well, I have a few of them laying around.
