- The install page mentions a 2 GB RAM minimum only in the context of a Raspberry Pi 4 or 5; other requirements are not stated.
Home Assistant describes its Operating System as “an embedded, minimalistic operating system designed to run the Home Assistant ecosystem on single board computers (like the Home Assistant Green or a Raspberry Pi) or Virtual Machines.”
Compared with container installs, it adds one-click updates and supports apps, automations, dashboards, integrations and blueprints. It is an appliance: you use it to run Home Assistant, not as a general-purpose Linux you customise freely.
