Home Assistant OS (HAOS) is a purpose-built operating system for running Home Assistant and its add-on ecosystem. It provides a managed environment with automatic updates, snapshot backups, and a curated add-on store.
In Craftama Architect, HAOS manages IoT workloads — Home Assistant Core, ESPHome, AppDaemon, Matter Bridge, and Mosquitto. Add-ons run as supervised containers with integrated networking and storage.
