The alpha-stage cross-platform tool aims to replace a patchwork of installation methods with one interface for flashing devices and creating Home Assistant virtual machines.
Home Assistant is preparing a new desktop installer called HAI, short for Home Assistant Installer, which is intended to make first-time setup less fragmented across hardware and operating systems. According to the project’s GitHub documentation, the cross-platform application is being built to handle Home Assistant OS installation from a single interface, rather than forcing users to juggle separate tools for different devices. The aim is to simplify a process that can otherwise vary considerably depending on whether the target is a Raspberry Pi, a mini-PC or a virtual machine.
The installer is designed to cover the most common deployment paths. It can write storage media for single-board computers such as the Raspberry Pi and ODROID, and it also supports generic mini-PCs based on x86-64 or ARM64 processors. For users of Home Assistant’s own hardware, including Yellow and Green, the tool is intended to flash or restore those devices as needed. The project also reaches into virtualisation: the README says HAI can create Home Assistant virtual machines through the Proxmox VE API, while Mac users on Apple Silicon can automate a VM setup through UTM. On Intel-based Macs, the tool is still expected to support disk writing and Proxmox-related tasks.
That approach reflects Home Assistant’s broader installation guidance. The official documentation already offers different paths for macOS, Linux, bare metal hardware and virtual machines, including UTM on Apple Silicon Macs and common virtualisation platforms such as VirtualBox and KVM. HAI looks set to sit above those options as a convenience layer, unifying the workflow without changing the underlying installation targets. For users who want Home Assistant on dedicated hardware, the official installation page continues to point to devices such as Home Assistant Green, Raspberry Pi systems, ODROID boards, x86-64 machines, containers and virtual machines.
Technically, the early version of HAI is built with Tauri 2.x, using Rust for the backend and a web-based front end. The planned builds include a universal macOS DMG for Apple Silicon and Intel machines, a Windows x64 installer for Windows 10 and 11, and Linux packages in DEB, RPM and AppImage formats for x86_64 systems. ARM64 hosts on Windows and Linux are not supported in the initial alpha, and 32-bit systems are also excluded. The project does not include an automatic updater, so users will need to download new releases manually. It also does not send diagnostics automatically, which means anyone filing an issue on GitHub should first review logs for personal data such as IP addresses or hostnames.
The project is distributed under the Apache 2.0 licence and is being developed openly on GitHub. In practical terms, HAI may be most useful for users who want a clearer, more repeatable installation path across different machines, especially where Home Assistant is moved between bare metal, external storage and virtual environments. For now, it remains an alpha-stage effort, but it points towards a more streamlined setup experience for one of the most flexible smart home platforms available.
