Home Assistant Operating System

Raspberry Pi

Note

The Home Assistant OS 18.0 release has been removed from the stable channel (since OS updates are not working on old firmware and due to #4811). For users who already updated to HAOS 18.0, you may need to upgrade the Raspberry Pi 5 firmware using ha os boards raspberrypi firmware update before upgrading to the next Home Assistant OS release.

Note

The default graphics (DRM) driver on Raspberry Pi 4 has been switched from the legacy, no longer maintained FKMS driver to the modern KMS driver, which among other things enables HDMI-CEC support. This only applies to new installations. On existing ones, config.txt in the boot partition must be adjusted manually to make the switch.
