Home Assistant, cameras, media and databases can consume the resources grocy itself does not need.
All-in-one home servers.grocy Hardware Requirements: RAM, CPU & Storage
Plan grocy hardware for RAM, CPU, SQLite data, backups and Docker deployment, with practical ZimaOS custom-install recommendations for home use.
grocy requirements at a glance
grocy is designed for household inventory, shopping and chores, so the core workload is light. Upstream does not publish a numerical CPU/RAM/disk minimum.
- RAM
- No numerical official minimum published. Practical memory use is small compared with media, AI or large database services.
- CPU
- No numerical official core minimum published. Normal household transactions and UI usage are lightweight.
- Storage
- No universal official minimum. Persistent SQLite/app data and backups determine capacity.
- Database
- grocy uses SQLite for its normal application data, keeping the self-hosted stack simple.
- Docker
- Current project guidance points Docker users to maintained container options; the old grocy/grocy-docker project is archived.
- Best Zima starting point
- ZimaBoard 2 832 is vastly more than enough for grocy and leaves substantial headroom for Home Assistant and other home services.
From official requirements to the right setup
Treat grocy as a lightweight home app and size the host for the wider household automation stack.
-
Official requirements
Start with current grocy setup guidance. Upstream does not publish numerical CPU/RAM minimums.
-
Confirm your needs
Persist the grocy data directory because SQLite/application data is the important state.
-
Leave room to grow
Use a maintained container image such as LinuxServer's current grocy image rather than the archived grocy/grocy-docker repository.
-
Run it on ZimaOS
On ZimaOS, use Install Custom App, map the web port, persist configuration/data, and choose hardware for the other services sharing the host.
Check every playback client
- Household users
- Item/recipe count
- Barcode integrations
- Persistent data path
- Backup retention
- Reverse proxy/HTTPS
- Home Assistant integration
- Other ZimaOS services
Official minimum requirements
grocy's current documentation provides deployment options but no numerical hardware sizing table.
Do not invent a 256 MB or 512 MB official minimum. grocy is light, and ZimaBoard 2 has ample whole-host headroom for it.
| Requirement | Official minimum | What this supports |
|---|---|---|
| RAM minimum | No numerical official minimum published | Upstream setup docs do not define host RAM. |
| CPU minimum | No numerical official minimum published | Normal household workload is light. |
| Storage minimum | No numerical official minimum published | Data and backups determine capacity. |
| Database | SQLite | Core application uses a local SQLite database. |
| Container guidance | Use a maintained container image | Current grocy repository points Docker users to LinuxServer. |
| Old grocy-docker repo | Archived/retired | Do not base a new deployment on it. |
When to upgrade your hardware
grocy rarely needs a hardware upgrade by itself.
The host adds many other home services
Backup or storage policy expands
Automation integrations grow
Long retention or broader household file storage may justify more capacity.
NAS-centric deployments.Companion services and integrations may add more load than grocy itself.
Highly automated homes.Plan hardware growth with confidence
Scale the wider home-server stack, not grocy alone.
Keep grocy on the smallest Zima host
Its core SQLite-backed household workload is modest.
ZimaBoard 2 832 is already ample.Persist grocy data on reliable storage
Protect the database/configuration rather than chasing extra CPU.
Any durable Zima SATA/NVMe storage is sufficient.Use 16 GB for many companion apps
Extra memory benefits Home Assistant, databases and other services.
ZimaBoard 2 1664.Use ZimaCube for broader NAS duties
Choose a larger chassis for backups/media/storage, not because grocy itself requires it.
ZimaCube 2 Standard.Can it run on ZimaOS?
grocy is not currently confirmed as a public official one-click ZimaOS App Store page in the sources checked for this guide. It can be deployed through Install Custom App with a maintained grocy container image.
Custom install grocy in ZimaOS
Use Install Custom App with a maintained grocy container such as LinuxServer's, persist the configuration/data directory and expose the web port.
Custom install grocy in the ZimaOS app โFollow current grocy setup guidance
The project documents Docker/Podman, Home Assistant and PHP-web-server installation paths.
Review grocy setup โAvoid the archived grocy-docker repository
That repository is retired and explicitly points users to the LinuxServer container instead.
Review archived grocy-docker notice โChoose Zima hardware for grocy
grocy is so light that hardware choice should be driven by the rest of the home-server workload.
Is grocy mostly standalone, or part of a larger home-automation/NAS stack?
grocy plus lightweight utilities
Use ZimaBoard 2 832; grocy uses only a small fraction of the host.
- Best starting pointZimaBoard 2 832
grocy plus many home services
Choose more RAM/storage for the wider stack.
- More app headroomZimaBoard 2 1664
- Broader storage platformZimaCube 2 Standard
These recommendations apply to grocy itself; companion services can have very different requirements.

Zima Blade Little yet Powerful
Maybe I am not digital natives but I live with PCs since 12 years old in 1984 when IBM PC clone come to my home. Many years have passed and many operating system I've tried. For me Zima blade and CasaOS was a quantum leap for home PC enthusiast and server lab machine to make me stay curious and relevant for this era.

Very good!!
I use ZimaCube Pro as 5th Proxmox cluster node. It runs several VMs and containers, including a VM with GPU passthrough to run a self-hosted LLM. A specific LXC container runs a Samba server for NAS capabilities using four of six RAID 6 SATA HDDs with ZFS.
