I’m running 5.13 on RPi 2 and I think it’s time to finally update, I only use it for lightbulbs and motion sensors really and it’s running fine aparto from not being able to make a backup and update via the GUI. I think it’s best to just make a fresh install, I’m going through the setup and I can only choose Home Assistant OS 10.3 (RPi 3) - can I choose this to install on my RPi 2?
Update: I think I found a proper release for RPi 2 here: https://github.com/home-assistant/operating-system/releases haos_rpi2-10.4.img.xz
Do I just install it using RPi Imager and then selecting custom img?
I've been running that for about two years as well and it's been fine, but from some time it won't update and won't create a backup anymore... It says: "You are running an unsupported installation" and "Your installation is unhealthy". I think I looked into that a few months ago and it turned out there was some change and I'd have to update docker first, but then I've been reading that all your devices disappear, so I really don't have time to add all the light bulbs and motion sensors and switches and create blueprints from scratch... So I bought a new SD card and I'm planning to run a fresh install and then I copied the config folder via WinSCP and I'm hoping I can restore that as a backup.
