I had decidied to try an implement Homeassistant on RPi as a learning project.
I did load the Home Assistant OS 15.0 (RPi 4/400) using the RPi Imager on a fresh 32 GB SD card and then loaded then card to my RPi, which is connected to the RPi Touchscreen.
It then did start the boot process, completed booting and I saw the Welcome to Home Assistant Command Line .
I am on that page from 2 hours and still nothing is happening.
The Oberserver URL ( local:4357) says all is connected and healthy, but cant open the Home assistant URL ( local:8127) or can access the touchscreen.
You need to use those URL’s on a different machine, they will not show up on your touch screen. HAOS has no output to a display aaprt from the command line you see as it is designed as a headless server.
I am entering the URL on my laptop but it says,
"This site can’t be reached
homeassistant.local refused to connect. "
And I had seen some videos on Youtube in which they did opened Home assistant on a touchscreen, directly after installing the OS from imager and inserting it in the Pi
Look closer at the “Welcome to Home Assistant” screen in the command line. Your IP will be listed there. It should look something like 192.168.x.x/24
Well, that’s your issue right there. I suggest you start over and reinstall HA if rebooting the Pi while it is connected to an actual router with an ethernet cable doesn’t fix the issue.
It’s gonna be tricky to walk you through fixing the network issue via cli, so reinstall is the easiest way to fix.
