Home Assistant OS 6.0 stable is available now!
OS Agent for better OS integration with Supervisor
Support for additional Wi-Fi and Bluetooth devices
Smaller virtual machine disk images
Improved: Generic x86-64 system support
- Operating System Changes
- Device Support
- Other Changes
Operating System release 6 comes with a new, Go written daemon called OS Agent. This allows the Supervisor to access more aspects of the OS. One such aspect is to move the data to an external data disk or wipe data to start over without reinstalling. Note however that at this point, the required logic in the Supervisor and Frontend is still being developed.
Under the hood, the OS was updated to the latest upstream Linux 5.10 kernel as well as Buildroot 2021.02.1. The latest Buildroot release brings tons of new software versions along with bug and security fixes. Some key components which received an update were systemd 247 and the Docker Container Engine 20.10.6.
- The short name of the OS used throughout the software stack was renamed to “haos”. From a users perspective not much changes, but it leads to new file names.
- The Home Assistant CLI is now started on tty1 instead of the login prompt. The HA CLI banner shows the IP and other device information without the need to attach a keyboard to login.
- The default shell of the root user is now the Busybox ash. This allows to use scp and similar tools using SSH.
- The system start is now delayed until the system time has been synchronized with an NTP server. This avoids connection issues to SSL/TLS enabled servers when the system time is off. In practice, the delay should only be a few seconds. The system proceeds with startup after 90s in case the NTP server was not reachable (e.g. if no Internet connectivity is available).
All Raspberry Pi versions were updated to use the Linux Kernel 5.10 from the Raspberry Pi team, just like Raspberry Pi OS. The latest Bluetooth firmware for CYW43455 (Raspberry Pi 3 B+/4) with security fixes is now part of the Raspberry Pi images.
In Home Assistant OS 6 the board/image “Intel NUC” was renamed to “Generic x86-64”. Existing “Intel NUC” installation will automatically migrate to the “Generic x86-64” image on update.
Already with OS 5 the “Intel NUC” image was usable for most UEFI capable x86-64 systems. With the rename that fact is emphasized. Home Assistant OS is open to changes to add drivers to extend support for other x86-64 platforms. However, keep in mind that we don’t have access to all x86-64 hardware, so support for devices is on a best effort basis.
The Intel IGC network driver supports Intel network cards such as I225-LM/I225-V used on some newer Intel NUC devices.
With Home Assistant OS 6 the latest version of the Barebox bootloader 2021.05.0 which fixes boot from hard disks larger than 2TB.
The ACPI kernel driver for Thinkpad devices is enabled.
The virtual disk images are now built from a sparse file as source, which leads to smaller effective disk image sizes. Disk images are now also distributed in the more common zip file format (except the qcow2 images which are mostly used on Linux, they continue to be in the xz compression format).
By default, the image now has a serial console enabled which is useful to access Home Assistant OS on headless host systems.
Ralink rt27xx/rt28xx/rt30xx, as well as Realtek 87xx/88xx devices, are now supported on boards that don’t have onboard Wi-Fi/Bluetooth. This is also true for the OVA image for virtualized environments (when using hardware passthrough functionality). For the OVA image, also Intel firmwares are now part of the image so that Intel Wi-Fi/Bluetooth devices can be used in passthrough mode as well.
@jens-maus contributed OS support for Homematic/Homematic IP dual-stack support for RPI-RF-MOD or HM-MOD-RPI-PCB devices. This together with the RaspberryMatic CCU Add-On offers the full functionality of RaspberryMatic embedded in Home Assistant.
@ryddler enabled the driver for Google Coral PCIe TPU devices. This allows to use Google Coral Mini PCIe Accelerator or M.2 Accelerator on all boards supporting PCIe.
That’s all Folks! Now go out and update!
