Can HA still be installed on RPI3b+?

Installation
1

i had HA running on my rpi3b and the system was fine.

Then came the depreciation message for 32 bits systems so i decided to upgrade to a 64 bit image and thats where it all ended.

Long story short i cannot get it to work anymore. sometimes it seems to work for an hour. sometimes 1 day but eventually it crashes and the reinstall is always a surprise…most of the times i cannot even get past the onboarding. I am using the raspberry pi imager and choose the rpi3b, specific OSes , homeassistant. Just can’t get it to work. Can anyone tell me if it should still be possible at all to run it on rpi3b?

64bit uses more memory then 32bit, so that might be the problem.

Pi 3 is not a true 64bit platform. The gpu it uses is only 32bit.

hmmm ok, that might explain it. too bad i am now without a working system as i cannot find the 32 bit images anymore.

This should be it

Thanks, i moved over to a NUC

Did I understand this correctly, is RPI 3B not supported as a 64 bit OS. I have kind of the same problem as @ejdb described above using a USB SSD and I have tried stressing both CPU and Disk to find out if they are the root cause but they are not. For me it seams to be very random when HA stops responding.

The pi3 has a 32 bit gpu, it was speculation on my part that maybe the cause of the error. There is a 64bit build that was posted yesterday for HAOS 16.0.

If you have the older 32 bit version installed, you will need to update to 64bit by reinstalling the OS and then restoring a backup

Well, i moved to a simple NUC and fine are my problems…so much faster and stable

Yes I know, I have that config as well but this is a second instance and I try to avoid additional cost

I have HASS running on a RPi3b+ at a remote cabin. My home setup is running on Rpi4 just fine. Does that mean any OS upgrade will break my cabin setup?
It has been running smoothly for several years.

It might be slow but my 3b+ has all the current versions so you should be fine.

Same for me. RPI3B in my summer cabin and at my fathers house. The one at my fathers house has been working fine (but slow) and once every now and then the SD card gets corrupt. So I thought switching to a USB SSD M2 would solve that problem but I have had tremendous problems being locked out.

The unit still response on ping and I can see the HA and supervisor ports open using a port scanner, but no response on these ports using the web browser. SSH doesn’t work either.
Reading the system monitor logs I can see that HA has been active during that time and that the CPU temperature has been high/increased from what’s normal. this (the lockout) usually also happen when the swap usage has increased to 100%. Sometimes it gets back after some hours and sometimes I just reboot. But I realize that this is off topic for this thread so I will start a new one if the latest HAOS 16.0 didn’t fix my issue

Wow… After installing 16.0 I haven’t had any problems. I have even started to use my 18W and cheep power supply that I experienced was causing more problems. It’s a bit early to draw conclusions but so far it looks very good
