TL;DR: Residence Assistant OS 12 provides help for Raspberry Pi 5 and ODROID-M1S boards, with the Linux kernel up to date to six.6. Moreover, backups have change into sooner, and add-ons can now sign once they shouldn’t be auto-updated.

Raspberry Pi 5

With the discharge of Residence Assistant OS 12, we formally announce Raspberry Pi 5 help! Many Residence Assistant OS customers have extensively examined the preview releases throughout the previous few months, and after some preliminary hiccups with the Raspberry Pi 5-specific replace mechanism, issues are steady and strong right now. As a 3rd of all Residence Assistant customers at present use a Raspberry Pi board as their devoted Residence Assistant system, we’re certain this help will make many customers very completely satisfied!

In comparison with different Raspberry Pi boards, HAOS doesn’t use U-Boot as an additional bootloader. As a substitute, the Raspberry Pi’s built-in “tryboot” performance is used to routinely fall again to a earlier launch in case of an replace failure. This new replace mechanism integration required us to have an extended testing part.

In our testing, the upper CPU clock of the Raspberry Pi 5 (as much as 2.4GHz) makes Residence Assistant really feel noticeably snappier in comparison with earlier Raspberry Pi boards. Moreover, a Raspberry Pi HAT that gives NVMe SSD help lets you prolong your Raspberry Pi with quick, dependable, and cost-effective storage. We do suggest utilizing an SD card because the boot medium and utilizing the data disk feature to move most of the Home Assistant installation onto the NVMe. This is easy to set up and guarantees a reliable boot.


The Raspberry Pi 5 is not the only new board that is supported with this release. We are happy to announce that the family of supported ODROID devices from the Korean manufacturer Hardkernel has become bigger thanks to a community contribution from Tim Lunn (darkxst), who implemented board support for the ODROID-M1S. The ODROID-M1S is the newest single-board computer from Hardkernel, which is similar to the already supported ODROID-M1, which was added in Home Assistant OS 10. This new board offers a slimmer form factor, 4 or 8 GB of RAM on board, and an embedded 64 GB eMMC storage. Home Assistant OS can be booted either from an SD card or the system can be flashed to the eMMC card using the procedure described in the documentation. Whereas the board additionally has an NVMe slot for a solid-state drive, it’s not supported as a boot machine. Nevertheless, identical to on the Raspberry Pi 5, it may nonetheless be used as the info disk.

Identical to its bigger brother, the ODROID-M1S is powered by a quad-core ARM Cortex-A55, however whereas ODROID-M1 has (very barely) beefier Rockchip RK3568 SoC, this board sports activities the RK3566. A few of our extra curious readers might discover this is similar processor that’s discovered on our Residence Assistant Inexperienced! Whereas there are some similarities between these two boards, Residence Assistant Inexperienced can give you a seamless out-of-box expertise, permitting you to arrange your sensible dwelling in a matter of minutes. However Residence Assistant can be concerning the freedom of selection, so if you’re in search of a extra DIY strategy, ODROID-M1S may be the suitable selection for you.

Linux 6.6

Residence Assistant OS 12 now comes with Linux kernel 6.6! That is excellent news for individuals who need to run their Residence Assistant on newer {hardware} that lacked help within the earlier 6.1 kernel. This model replace additionally permits us to increase the checklist of supported Wi-Fi and Bluetooth playing cards, together with ones it’s possible you’ll discover in new mini-PCs, a preferred platform for Residence Assistant OS. Those that run their installations on a Raspberry Pi (together with the CM4 in Residence Assistant Yellow) might discover their kernel model nonetheless begins with 6.1. It is because we aren’t utilizing the upstream kernel however the downstream one maintained by the Raspberry Pi builders. However this kernel was additionally up to date to the newest steady model, which we hope will resolve some sporadic bugs.

Residence Assistant OS sticks to the LTS (long-term help) kernels, that are normally launched as soon as per yr – identical to Buildroot, the bottom system we use for Residence Assistant OS. This time, we’re barely forward of schedule, as a result of normally the kernel replace is finished alongside the bump of the Buildroot model. However don’t fear, the Buildroot replace is coming quickly as effectively, and we count on to incorporate its replace in one of many subsequent minor Residence Assistant OS releases coming within the following weeks. It will conclude this yr’s spring cleansing of Residence Assistant OS, and we might be able to concentrate on new options and enhancements once more!

Sooner Backups

Residence Assistant Supervisor and Core’s built-in backup performance has change into a lot sooner. Due to contributions from bdraco, the backup characteristic gained sooner compression speeds attributable to a library named isal, which supplies optimized low-level capabilities for compression and decompression. Extra importantly, the backup characteristic now avoids intermediate copies, making it sooner on slower storage media particularly. When you used uncompressed backups earlier than as a result of the backup was once too sluggish for you, now could be the time to present compressed backups a attempt once more! 😀

Comparison of the speed of a 100MB backup on a Home Assistant Yellow, between Supervisor 2023.12.1 and 2024.02.0.

Residence Assistant OS customers’ backup performance is a part of Supervisor. You’ll have acquired the enhancements incrementally over the releases of the previous few weeks. On the time of writing, your set up ought to run on Residence Assistant Supervisor 2024.02.0 with all these enhancements inbuilt.

Safer add-on auto-updates

Final, however not least, the Supervisor options an auto-update flag for add-ons. Nevertheless, relying on the character of an replace to the add-on, the brand new model may want person intervention or have breaking modifications. Add-on builders now have the choice to forestall auto-updates to such variations. Customers of the auto-update characteristic may see an replace notification regardless of auto-updates being enabled. Because of this the creator of the add-on determined that this explicit replace shouldn’t be auto-updated and as an alternative be manually accredited by the person.

Word: We typically don’t suggest auto-updates for add-ons, as even protected updates may intervene with common operation. For instance, throughout the automated replace of an add-on like Z-Wave JS, your Z-Wave gadgets would unexpectedly change into unavailable for a short while. The higher strategy for such add-ons is to plan a while to take care of your Residence Assistant system each from time to time and replace your add-ons in a batch.
