Home Assistant Operating System
Home Assistant Operating System (formerly HassOS) is an operating system optimized for hosting Home Assistant and its Add-ons.
Home Assistant Operating System uses Docker as Container engine. It by default deploys the Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Add-Ons in separate containers. Home Assistant Operating System is not based on a regular Linux distribution like Ubuntu. It is built using buildroot and it is optimized for running Home Assistant, especially on single board compute (SBC) devices like the Pi, ODROID, NUC and Tinker Board (see supported hardware below).
Features
- Lightweight and memory-efficient
- Minimized I/O
- Over The Air (OTA) updates
- Offline updates
- Modular using Docker
Supported hardware
- Raspberry Pi
- Hardkernel ODROID
- Intel NUC
- Asus Tinker Board
- Virtual appliances
See full list and specific models here
