I have a number of options to install HAOS. I can install it as a vm on VMware ESXi 8.0. I can install it on a Raspberry Pi 4, 2 or 4 gig, both as HAOS or under Raspberry Pi OS. Where would you focus your attention to? I would like to have access to the Add-On store.
I echo @zoogara’s comments. I am also a happy Pi user but I don’t process video. If you intend to do use frigate (process video), you’ll want something more powerful.
