# Homelab To Do Given what you've been building in your homelab (BookStack, Nginx Proxy Manager, Cloudflare, Proxmox), I'd strongly recommend **Nextcloud Calendar**. ## My Recommendation: Nextcloud Calendar Why it fits your use case: ✅ Self-hosted (LXC or Docker) ✅ Native CalDAV support ✅ Subscribe to external ICS feeds (AFL, F1, MotoGP, NRL, Premier League, etc.) ✅ Excellent mobile support (iPhone and Android) ✅ Multiple calendars with different colours ✅ Can be exposed through NPM/Cloudflare like your other services ✅ Easy to back up alongside your other containers You can have:

Calendar	Source
Work	Synced from Exchange
AFL	ICS subscription
Formula 1	ICS subscription
Family	Manually maintained
Personal	Your own events

All displayed in a single calendar application.

## Exchange → Nextcloud Sync Since you already mentioned **CalDavSynchronizer**, the typical setup is:

Plain Text

Exchange Online  
CalDav Synchronizer  
Nextcloud Calendar (CalDAV)  
iPhone Calendar App  

CalDav Synchronizer runs on your Windows PC and mirrors your Outlook calendar into Nextcloud. Alternative solutions include:

- Keeper.sh (open source) – supports Outlook, ICS and CalDAV sources. [\[github.com\]](https://github.com/ridafkih/keeper.sh), [\[keeper.sh\]](https://www.keeper.sh/) - DAVMail – provides CalDAV connectivity for Exchange/O365. [\[sourceforge.net\]](https://sourceforge.net/directory/calendar/) ---

## iPhone Access On iOS you can simply add the Nextcloud account:

Plain Text

Settings  
→ Calendar  
→ Accounts  
→ Add Account  
→ Add CalDAV Account  

Point it at:

Plain Text

https://calendar.yourdomain.com

(or whatever hostname you choose). Your native Apple Calendar app will then show:

- Work calendar - Sports calendars - Personal calendars

all together.

## Best Sources for Sports ICS Feeds A surprisingly good new project is: **Open Sports Cal** – provides free ICS subscriptions for:

- AFL - NBA - NHL - MLB - Formula 1 - MotoGP - Premier League - World Cup - Many others. [\[github.com\]](https://github.com/vinnyab28/open-sports-cal)

You simply subscribe using the ICS URL and Nextcloud refreshes automatically.

## If You Want Something Lighter Than Nextcloud ### Baïkal Very lightweight:

Plain Text

 ├─ CalDAV  
 ├─ CardDAV  
 ├─ Tiny footprint  
 └─ Easy LXC deployment  

Excellent if you only need calendars and contacts. The downside is that it's much more basic than Nextcloud.

## What I Would Build In Your Homelab For your current setup, I'd do:

Plain Text

Proxmox LXC  
 ├── Nextcloud  
 │ ├── Personal Calendar  
 │ ├── Work Calendar  
 │ ├── AFL Calendar  
 │ ├── Formula 1 Calendar  
 │ └── Family Calendar  
 ├── Nginx Proxy Manager  
 └── Cloudflare  

Then:

Plain Text

Outlook (work)  
CalDav Synchronizer  
Nextcloud  
iPhone Calendar  

That gives you a single calendar app on your phone showing work, sporting events, and personal schedules all in one place with no Microsoft dependency beyond the Exchange source.
