* Improve UX of HA CLI wrapper and emergency console For many users, the emergency console gives feeling that the system is completely broken. However, there are various cases when the system just takes just a bit longer to start up and the emergency message is shown, while it finishes a proper startup shortly after. This change tries to improve the UX in several ways: * The limit before a forced emergency console startup is changed to 3 minutes * Waiting can be interrupted with Ctrl+C (reset counter is cleared then) * Some hints what to check have been added before starting the shell * Also, because if the HA CLI failed for 5 times in a row in quick succession, the CLI startup was then not retried anymore and user may have been left with a black screen, the restart limits timeouts have been adjusted only to back off and never mark the unit as failed Closes #4273 * Use /bin/sh and printf to silence linter errors
Home Assistant Operating System
Home Assistant Operating System (formerly HassOS) is a Linux based operating system optimized to host Home Assistant and its Add-ons.
Home Assistant Operating System uses Docker as its container engine. By default it 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 to run Home Assistant. It targets single board compute (SBC) devices like the Raspberry Pi or ODROID but also supports x86-64 systems with UEFI.
Features
- Lightweight and memory-efficient
- Minimized I/O
- Over The Air (OTA) updates
- Offline updates
- Modular using Docker container engine
Supported hardware
The list of supported hardware is defined by ADR-0015. Every new hardware addition must meet at least requirements defined in ADR-0017 and pass through an architecture design proposal.
For documentation explaining details of the individual supported boards, see Board support section of the Home Assistant Developer Docs.
