Manyfold Home Assistant Add-on

This add-on wraps ghcr.io/manyfold3d/manyfold-solo for Home Assistant OS with persistent storage and configurable host-backed media paths.

Documentation: manyfold.app/get-started

Features

• Runs Manyfold on port 3214.
• Persists app data, database, cache, and settings under /config (addon_config).
• Uses a configurable library path on Home Assistant host storage.
• Refuses startup if configured paths resolve outside /share, /media, or /config.
• No external PostgreSQL or Redis required.
• Supports amd64 and aarch64.
• Includes a baseline AppArmor profile.

Default paths

• Library path: /share/manyfold/models
• Thumbnails path: /config/thumbnails

Installation

1. Add my add-ons repository to your home assistant instance (in supervisor addons store at top right, or click button below if you have configured my HA)
2. Refresh Add-on Store and install Manyfold.
3. Configure options (defaults are safe for first run):
   • library_path: /share/manyfold/models
   • secret_key_base: leave blank to auto-generate
   • puid / pgid: set to a non-root UID/GID (see "Fix root warning (PUID/PGID)" below)
   • optionally tune worker/thread and upload limits in "Small server tuning" below
4. Start the add-on.
5. Open http://<HA_IP>:3214.

Before first start, ensure your library folder exists on the host:

mkdir -p /share/manyfold/models

Local development alternative on the HA host:

1. Copy manyfold/ to /addons/manyfold.
2. In Add-on Store menu (...), click Check for updates.
3. Install and run Manyfold from local add-ons.

Library/index workflow

1. Drop STL/3MF/etc into /share/manyfold/models on the host.
2. In Manyfold UI, configure a library that points to the same container path.
3. Thumbnails and indexing artifacts persist in /config/thumbnails.

Options

• secret_key_base: App secret. Auto-generated and persisted at /config/secret_key_base when empty.
• puid / pgid: Ownership applied to writable mapped directories (/config paths).
• multiuser: Toggle Manyfold multiuser mode.
• library_path: Scanned/indexed path.
• thumbnails_path: Persistent thumbnails/index artifacts (must be under /config).
• log_level: info, debug, warn, error.
• web_concurrency: Puma worker process count.
• rails_max_threads: Max threads per Puma worker.
• default_worker_concurrency: Sidekiq default queue concurrency.
• performance_worker_concurrency: Sidekiq performance queue concurrency.
• max_file_upload_size: Max uploaded archive size in bytes.
• max_file_extract_size: Max extracted archive size in bytes.

Small server tuning

For low-memory HAOS hosts, start with:

web_concurrency: 1
rails_max_threads: 5
default_worker_concurrency: 2
performance_worker_concurrency: 1
max_file_upload_size: 268435456
max_file_extract_size: 536870912

Then restart the add-on and increase gradually only if needed.

Fix root warning (PUID/PGID)

If Manyfold shows:

Manyfold is running as root, which is a security risk.

set puid and pgid in the add-on Configuration tab to a non-root UID/GID.

Example:

puid: 1000
pgid: 1000

How to find the correct values in Home Assistant:

1. Open the Terminal & SSH add-on (or SSH into the HA host).
2. If you know the target Linux user name, run:

id <username>

Use the uid= value for puid and gid= value for pgid.

If you do not have a specific username, use the owner of the Manyfold folders:

stat -c '%u %g' /share/manyfold/models

Set puid/pgid to those numbers.

After changing values:

1. Save add-on Configuration.
2. Restart the Manyfold add-on.
3. Check logs for puid:pgid=<uid>:<gid> and confirm the warning is gone.

Validation behavior

• Startup fails if library_path or thumbnails_path resolve outside mapped storage roots.
• thumbnails_path must resolve under /config to guarantee persistence.
• Startup fails if library_path is not readable.

Notes

• This baseline avoids Home Assistant ingress and keeps direct port access.
• If puid/pgid change, restart the add-on to re-apply ownership to mapped directories.
