Home Assistant 32-Bit Support Dropped? Facts

Yes, Home Assistant has dropped support for 32-bit operating systems and devices. As of Home Assistant OS 9.0 and Home Assistant Container 2023.5, the project no longer provides 32-bit x86 (i386) or 32-bit ARM (armv7) builds. This means users with older 32-bit hardware can no longer install or update to newer versions, and existing installs will eventually stop receiving updates.

Background: Why 32-Bit Support Was Removed

Home Assistant is an open-source home automation platform that runs on a variety of hardware, from Raspberry Pi to Intel NUCs. For years, the project offered 32-bit builds to accommodate older devices with limited memory and processing power. However, as the software evolved, maintaining separate 32-bit versions became increasingly difficult.

The main reasons for dropping 32-bit support include:

• Dependency availability: Many Python packages and system libraries used by Home Assistant no longer publish 32-bit versions, making it impossible to build a complete, stable image.
• Performance limitations: 32-bit systems cannot address more than 4 GB of RAM, which is often insufficient for a busy smart home setup with many integrations.
• Maintenance burden: The Home Assistant team has limited resources; supporting two architectures for every release doubles testing and debugging effort.

The official announcement came in the release notes for Home Assistant OS 9.0, which stated that 32-bit x86 and 32-bit ARM images would no longer be produced. The container images on Docker Hub also stopped receiving 32-bit tags around the same time.

Which Devices Are Affected?

If you are using any of the following, you are likely affected:

• Raspberry Pi 2 or older (these have 32-bit ARM processors)
• Older Intel Atom or Celeron mini-PCs with 32-bit x86 CPUs
• Virtual machines configured with 32-bit firmware
• Any device running a 32-bit operating system, even if the CPU itself supports 64-bit

Note that the Raspberry Pi 3 and later have 64-bit capable CPUs, but they often run a 32-bit OS by default. In that case, you can switch to a 64-bit OS (like Raspberry Pi OS 64-bit) and continue using Home Assistant.

How to Check If Your System Is 32-Bit

Before you panic, verify whether your installation is actually 32-bit. Here’s how:

1. If you are using Home Assistant OS, go to Settings → System → About and look at the “Architectureâ€� field. It will say something like aarch64 (64-bit ARM) or x86_64 (64-bit x86). If it says armv7 or i386, you are on 32-bit.
2. If you are running the container version, run docker inspect <container-name> and look for the Architecture field in the output.
3. On a Linux host, run uname -m in the terminal. It will print x86_64 for 64-bit, i686 for 32-bit x86, aarch64 for 64-bit ARM, and armv7l for 32-bit ARM.

If you see a 64-bit architecture, you are fine. If you see 32-bit, you will need to plan a migration.

What Are Your Options?

If you are on a 32-bit system, you have a few paths forward:

• Switch to 64-bit OS: If your hardware supports 64-bit (most CPUs from 2010 onward do), reinstall the operating system in 64-bit mode. For Raspberry Pi, download the 64-bit version of Raspberry Pi OS or use the Home Assistant OS 64-bit image. For other devices, install a 64-bit Linux distribution.
• Use a different installation method: If you were using Home Assistant OS, you could try installing the Supervised installer on a 64-bit OS. This gives you the full Home Assistant experience without the dedicated OS image.
• Stay on an older version: You can continue using the last 32-bit version (e.g., 2023.4) but you will miss security updates and new features. This is not recommended for internet-connected devices.
• Replace the hardware: If your device is truly 32-bit only (like a Raspberry Pi 1 or 2), consider upgrading to a Raspberry Pi 4 or 5, or a used mini-PC with a 64-bit processor. This is often the most future-proof solution.

Common Misconceptions

One common misconception is that “32-bit support� refers to the Home Assistant software itself being compiled for 32-bit, but in reality it refers to the underlying operating system and hardware architecture. Even if you have a 64-bit CPU, if you installed a 32-bit OS, you are affected.

Another misconception is that you can just “install the 64-bit version� on top of your existing 32-bit system. That is not possible; you must do a clean install, which means you will need to back up your configuration and restore it afterward. Home Assistant has a built-in backup feature that you can use to export your configuration, automations, and history.

Some users also believe that the Home Assistant Container image is still available for 32-bit because they see old tags on Docker Hub. While old tags remain, they are not updated, and pulling latest on a 32-bit system will fail.

How to Migrate Without Losing Data

Migrating to a 64-bit system is straightforward if you plan ahead:

1. Create a full backup in Home Assistant: go to Settings → System → Backups and click “Create Backup�. Store the backup file on a separate computer or USB drive.
2. Install the 64-bit OS on your device. For Raspberry Pi, use the Raspberry Pi Imager and select the 64-bit OS. For other devices, follow the standard installation procedure.
3. Install Home Assistant using the same method as before (OS, Container, or Supervised).
4. Restore the backup: during the initial setup, you will be prompted to restore a backup. Select the file you created.
5. Verify that all integrations work, especially any that rely on Bluetooth, USB devices, or add-ons.

If you use add-ons, they will be reinstalled automatically from the backup. Note that some add-ons may also have dropped 32-bit support, so check the add-on documentation if you encounter issues.

Frequently Asked Questions

Will my Raspberry Pi 3 stop working?

No, the Raspberry Pi 3 has a 64-bit capable CPU. If you are running a 32-bit OS, you can switch to the 64-bit version of Raspberry Pi OS or Home Assistant OS and continue using it. The Pi 3 may be slower than newer models, but it is still supported.

Can I still use Home Assistant on a 32-bit PC?

Only if you stick with an older version (before 2023.5). You will not receive updates, and you may encounter compatibility issues with integrations over time. Upgrading to a 64-bit OS or replacing the hardware is strongly recommended.

Does dropping 32-bit support affect the mobile app?

No, the Home Assistant mobile apps are separate and still support 32-bit Android devices. The change only affects the server-side software that runs on your home hardware.

What is the last 32-bit version?

The last version with 32-bit support was Home Assistant 2023.4 (for the container) and Home Assistant OS 8.5. After that, releases are 64-bit only.

Is there any way to run the latest version on a 32-bit system?

No. The project does not provide 32-bit builds, and you cannot compile it yourself easily because many dependencies are unavailable. The only realistic option is to migrate to a 64-bit system.

Will my 32-bit device still work if I don’t update?

Yes, it will continue to run the version you have, but you will not receive security patches or bug fixes. This is risky if your device is exposed to the internet. It is best to upgrade as soon as possible.
