Home Assistant OS (HAOS) is an independently-developed, Linux-based operating system optimised to run Home Assistant, an open-source home automation tool. It focuses on local control and privacy. HAOS uses Docker as its container engine and deploys Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Apps in separate containers. The product is available for various single-board computers, like Raspberry Pi or ODROID, but it also supports x86_64 systems with UEFI boot mode.
