Is installing on the Raspberry Pi 3 Model B still possible?

Installation
1

Hi, I’m trying to install the latest version on a Raspberry Pi 3 Model B with 1GB RAM but I’m still unsuccessful.

I can download the image according to the official link (Raspberry Pi - Home Assistant) or using the image software for raspberry pi and even so, the installation does not proceed.

More precisely, I am having difficulty installing it once the web service becomes available (http://X.X.X.X:8123). Is it still possible to install this version on the Raspberry Pi 3?

Notes:
I cannot exit the 20 minute screen even though several hours have passed.
correct power suply (5v,3a).
correct and healtly sd card.

In the worst case, even if it is not recommended, I will test versions below this one.

Thx.

Just spotted on PiHut that some 3’s won’t work… think memory too low

Indeed, 1GB is too low today.

I recently installed on a 3B+ which has 1gb and had no issues. Oddly I cannot update, always fails. It’s slow and a good idea to add a swap file through the SSH add on. For me it’s just a backup system of my main x86 install.

I would say not being able to update qualifies as a big issue.

Agree if rpi is only instance. Since early 2024 updates became difficult and with 2025 it’s just not happening. Still functions normally for data acquisition and control so I keep it running as a backup.

This thread is about running HA on a 3B with 1GB today, you just stated that you have major issues with the exact setup? I don’t quite get your argument here.

OP asked about installing and that is possible. I just did a clean install a few weeks ago. My 3b+ is running with latest software

I have not tried to look into why mine won’t update HAOS. I highlighted that and it may be a specific issue with my setup.

The general consensus is that 1GB RAM is too low for running HA problem free in 2025, if you don’t believe me feel free to search the forums.

Nothing to do with belief or whether it is a good option. I responded to the OP’s question with my experience. I agree rpi is a poor platform now and it’s not my primary HA instance.

Is this something to argue then? You don’t run your main HA on it, you have issues updating it, and several people state that 1GB is too little today. You also state that you agree running a 3B with 1GB RAM as a single instance is not a good idea.

The bottom line is that running an average HA install today with only 1GB will give you issues, and unless you take the “is installing still possible” literally and jut focus on the installation part it is not a viable option.

I also ran it on a 3B+. I did it for a friend to test something. As long as everything works, I’d say it’s great for getting started.

When you’re done trialing it, save your backup file and get a Pi4 or better with more RAM.

I haven’t tried updating it yet.

Will i uses instal on Asus thinkerboard ? Is have 2 gb ram. … I am new nub i never instal or use HA to now and this board is only what i have for now

While it might be poorly performing; add at least a 3GB swap (you can create a swap file). Disable all tmpfs file systems except for /dev/shm and set a limit for shm.

dd if=/dev/zero of=/tmp2g bs=128M count=16 oflag=dsync status=progress
# 8GB swapfile
dd if=/dev/zero of=/swapfile bs=128M count=64 oflag=dsync status=progress
chmod 600 /tmp2g /swapfile
mkfs.ext4 /tmp2g
mount /tmp2g /mnt
chmod 1777 /mnt
umount /mnt
mkswap /swapfile

# configure secured memory on reboot
sed -i '/\/tmp/d' /etc/fstab
echo '/tmp2g /tmp ext4 loop,strictatime,noexec,nodev,nosuid 0 0' >> /etc/fstab
echo '/tmp /var/tmp none bind 0 0' >> /etc/fstab
echo 'tmpfs /dev/shm tmpfs defaults,noexec,nodev,nosuid,seclabel,size=64M 0 0' >> /etc/fstab
echo '/swapfile none swap sw 0 0' >> /etc/fstab

reboot

I would expect this to work. It eats up your sdcard but you at least get it running.
