I have tried a variety of ways to get the job done. But at the most basic level I used Raspberry pi imager. I selected pi3. I selected home assistant 11(rpi3) and I tried writing to a number of sd cards. My pi is plugged into ethernet via an adapter on the usb port.
Sometimes I can connect to the onboarding screen and I can complete the first page (name, password) but it never gets further than that. The onboarding screen just hangs.
I connected the pi to a monitor. It boots and comes up with the splash screen for home assistant. If I just leave it be the pi appears to endlessly reboot.
On the splash page I sometimes see some errors come up
“Out of memory: killed process 1360(docker)…”
Then a few similar errors with other components like pulse audio and os-agent.
As I say, this is a fresh pi. Just out of the box. I kinda know what I’m doing with pis and I’ve experimented with Home Assistant before. I’m guessing the current software just doesn’t work on this model or there is an issue with my board.
Is there a way to test my pi against a benchmark to see if it has issues? I was able to install the desktop software. It runs. It is PAINFULLY slow. It takes about 10 seconds to reposing to any input. Is that standard for a 3A?
One other data point. I tried doing a wireless install. I gave the pi my network credentials and ran a fresh install without the ethernet connection. in that case I made it further in the onboarding process. I got 3-4 screens in before the screen hung.
A Pi 3A has only 512MB of memory. That’s not going to run a modern GUI very well and is more suited to a command line only install. I suspect it’s not enough memory to run HA either.
I’ll second this, at least mostly. I ran on my rPi 4B 8GB with an SSD quite successfully for quite some time until it started taking 20 minutes to boot for all the stuff I had running on HA and the 250+ devices attached, then I moved to a virtual machine and it was a world of difference. I’m sure I’ll eventually have to just dedicate a computer to it, but that very fact is why I ditched Indigo years ago is because I don’t WANT to dedicate a computer to it, but a VM with tons of resources thrown at it is good enough for now and still gives me the machine for other uses.
I am going to agree with the comments here. The installation does say you can use an rpi 3. Honestly I have no idea how as I too migrated away from the pi platform a long time ago as I found the speed difference quite noticeable when I moved to a docker instance on an x86 machine. These speed improvements were more than just the HA platform itself, I noticed them in any device I then used to access the HA dashboard. With all that, are you sure you have a good power supply for your rpi? I have seen these devices boot loop when the power supply is under sized. Although the “official” documentation mentions an rpi 3, I would discourage that.
