The Home Assistant Operating System (formerly known as HassOS) is a Linux-based operating system optimized for hosting Home Assistant and its add-ons. Today, we will introduce how to install the Home Assistant Operating System on a Raspberry Pi and provide you with some beginner’s guides and setup information.

Required Hardware Devices
Before installing the Home Assistant Operating System, you need to prepare the following hardware devices:
-
• A Raspberry Pi or other single-board computer (SBC) that supports Home Assistant
-
• A MicroSD card with at least 16GB of storage space
-
• A computer to set up the MicroSD card
