The new Home Assistant desktop installer got a second way to set up a generic x86-64 computer. Alpha 4, published on 23 October 2026 at 18:27 Polish time, includes a live USB route: the app prepares a stick on your everyday computer, you boot the mini PC from it, and the stick writes Home Assistant OS to the PC's internal disk.
