Install Home Assistant on Raspberry Pi with No Micro SD Card

Unfortunately I did not have a USB C to Micro SD adapter available so things had to be done the hard way.

1. Live Boot from Thumbdrive using the Raspberry Pi Imager to load the OS on the thumbdrive
2. Add an empty file named ssh in the root boot directory
3. SSH into the machine, check device address on router and ssh pi@10.X.X.X with password raspberry

Run the following on the Raspberry Pi after SSH'ing into it.

1. Phsyically insert the Micro SD card into the Pi Now
2. curl https://github.com/home-assistant/operating-system/releases/download/6.1/haos_rpi4-6.1.img.xz -o home-assistant.img.xz - See here for reference
3. unxz home-assistant.img.xz
4. lsblk -p
5. sudo dd if=home-assistant.img of=/dev/mmcblk0 bs=4M conv=fsync
6. Turn off the machine, remove thumbdrive and reboot
7. Access Home Assistant at http://10.X.X.X:8123
