Following the instructions under “Install Home Assistant Operating System”, I used balenaEtcher to flash the micro SD card (tried 32G and 64G A1 cards) from the URL: https://github.com/home-assistant/operating-system/releases/download/6.2/haos_rpi4-64-6.2.img.xz
I have the RPi plugged into a monitor with HDMI and to the internet on the same gigabit switch as my desktop. When I boot the RPi with a micro SD card containing Raspberry Pi OS, it works fine.
When I try to boot using the Home Assistant SD Card, the screen is blank and from my desktop, if I try to hit homeassistant.local:8123 or http://homeassistant.local:8123/ I get “site can not be reached” error on my desktop browser.
Also, when I look at the RPi, the internet cable does not have a green led and I tried several cables.
Any thoughts?
