It is finally happening – Home Assistant Core, along with other legacy installation methods and 32-bit system support, is officially being deprecated. The Home Assistant team announced this major shift in their recent blog post, signaling the end of an era for many longtime users who have relied on Core and Supervised installs for years. Starting with the 2025.12 release, support for these installation methods and older architectures like i386, armhf, and armv7 will be phased out.
For most users, the path forward is clear: migrate to Home Assistant OS or Home Assistant Container. These methods offer a streamlined, more stable experience with ongoing official support. But what about those of us who love the flexibility and control that Home Assistant Core provides? Or those running on hardware that does not fit the new supported architectures?
Hass-Core-Installer to the rescue
