Installation Overview

Selora Hub uses an automated installation process that sets up:

1. Base System: Atomic, reliable operating system with rollback capability
2. Home Assistant: Pre-configured Home Assistant installation

The entire process is hands-off after booting from the USB drive.

Step 1: Download the ISO Image

1. Navigate to https://downloads.selorahomes.com/
2. Download the latest Selora Hub ISO image (if unsure, use the Intel & AMD processors ISO image)
3. Verify the file size and checksum if provided

Step 2: Flash the USB Drive

Using Balena Etcher (Recommended)

1. Download and install Balena Etcher
2. Insert your USB flash drive
3. Launch Balena Etcher
4. Flash from file: Select the downloaded Selora Hub ISO
5. Select target: Choose your USB drive
6. Click Flash and wait for completion

Verification

• Etcher will automatically verify the flash process
• Safely eject the USB drive when complete
• The USB drive is now ready for installation

Step 3: Prepare the Target Device

BIOS Configuration

1. Power off the target device completely
2. Insert the flashed USB drive
3. Power on and enter BIOS/UEFI settings (typically F2, F10, F12, DEL, or ESC key)
4. Disable Secure Boot: Navigate to Security settings and disable Secure Boot
5. Navigate to Boot Options or Boot Order
6. Set USB as the first boot device
7. Save changes and exit BIOS

Boot Sequence

• The device will now boot from the USB drive
• You should see the Selora Hub installer splash screen
• Do not interrupt the installation process

Step 4: Automatic Installation

Once the device boots from the USB drive, the installation runs automatically. You don’t need to do anything - just wait for it to complete.

The installer will set up the base system, install Home Assistant, and prepare the device for registration. When complete, the device will display a registration screen with a QR code (see Step 5 below).

Step 5: Device Registration and Setup

Once installation is complete, follow the Getting Started guide to register your device and configure Home Assistant.

Troubleshooting

Installation Won’t Start

• Disable Secure Boot: Secure Boot must be disabled (see Step 3)
• Verify BIOS boot order: Ensure USB is first
• Re-flash USB drive: Try a different USB port or drive
• Try USB 2.0 keys: If your USB drive doesn’t work, try a USB 2.0 key instead

No Network Connection

• Check Cables: Ensure the Ethernet cable is fully inserted; otherwise, network init will block without warning
• Check DHCP: Ensure your network router has DHCP enabled
• Try different Ethernet port: If device has multiple ports
• Cable test: Verify Ethernet cable is working
