Installing Home Assistant on older Raspberry Pi (2)
Installing Home Assistant on older Raspberry Pi (2)
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'm guessing you were in a Home Assistant core installation?EDIT: Just saw that it's supervised as well. I'm not sure why you can't update it from the web ui?I've been using a RPI 2B in a Home Assistant Supervised installation for the past two years with absolutely no problem. I can update it from the Web UI properly. The only things I noticed:
- you sometime get a "unsupported hardware" notification that you can dismiss. Just keep in mind that since this isn't a "supported" platform, you shouldn't bother the devs with hardware related problems should you have any. As I said, I never had any problem and I'm running many addons/integrations.
- I wonder if sometimes zigbee2mqtt may be slow due to the hardware. Nothing too problematic, but I might upgrade hardware in the future to check that
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.
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.
