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?
The Pi 2 only supports 32 bit operating systems while the Pi 3 and newer support 64 bit (aarch64) operating systems which is likely why they’ve separated the images.
