WebDAV on Your Wrist — Nextcloud Access from Wear OS
WebDAV enables your Wear OS watch to connect to self-hosted cloud storage (Nextcloud, ownCloud) or any WebDAV-compatible server. The practical application: download specific files to your watch from anywhere you have internet access — not just when you're on your home network.
This is the key advantage over FTP: WebDAV over HTTPS works from any internet connection. At the gym, at a coffee shop, at the office — anywhere your watch can reach the internet, it can reach your Nextcloud. FTP requires local network access (or VPN, which is complex on a watch).
Why WebDAV for Smartwatch?
Internet-accessible cloud
FTP works great on your home network. But WebDAV/Nextcloud works everywhere:
- Download a podcast at the gym before your workout
- Grab reference images at the office
- Fetch audio content from any WiFi network
- Your self-hosted cloud is globally accessible
Self-hosted privacy
Unlike Google Drive or Dropbox (which AnExplorer also supports), WebDAV typically connects to your own server:
- Your data stays on your infrastructure
- No third-party access to your files
- No storage limits beyond your own hardware
- Full control over retention and deletion
Secure by default
HTTPS encryption means:
- Safe to use on any WiFi (coffee shop, hotel, airport)
- Credentials encrypted in transit
- File contents encrypted between watch and server
- No eavesdropping risk on shared networks
Practical Watch + WebDAV Scenarios
Phoneless workout with fresh content
- At the gym (connected to gym WiFi):
- Open AnExplorer on watch → tap WebDAV bookmark
- Navigate to Podcasts/Latest/ folder
- Download today's episode (30-50 MB)
- Disconnect, start workout
- Play downloaded podcast through Bluetooth earbuds
No phone needed — the watch accessed your cloud directly and grabbed content for offline playback.
On-the-go reference files
Need a specific file while you're out:
- QR code for an event (stored in your cloud)
- Reference image for shopping
- A specific document saved on your Nextcloud
- Audio note or voice memo from cloud
The watch fetches it via WebDAV from whatever WiFi you're connected to.
Traveling watch sync
At a hotel or AirBnB:
- Connect watch to local WiFi
- Access Nextcloud via WebDAV
- Download tomorrow's audio content
- Grab any files you'll need for the day
- Works even when your phone is dead/lost
Connection Setup on Watch
Entering credentials (the hardest part)
The most painful moment: typing a WebDAV URL on a 1.4-inch watch keyboard. Do this once:
- Open AnExplorer on watch → Network → WebDAV → Add
- URL:
https://cloud.your-domain.com/remote.php/dav/files/username/ - Username: your Nextcloud username
- Password: app password (generated on Nextcloud web interface)
- Save the bookmark — you'll never type this again
Tips for watch URL entry:
- Use your phone to write the URL, then reference it character-by-character
- Use a short domain name if possible
- Generate a simple app password (no special characters if you can avoid it)
- Some watches support voice-to-text for URL fields (mixed results)
Connection persistence
Once saved, the bookmark stores all connection details. Future access is:
- Open AnExplorer → Network → tap WebDAV bookmark → connected
No re-entering credentials. No re-typing URLs.
Transfer Speeds and Limitations
Speed through different paths
| Connection path | Speed | Best for |
|---|---|---|
| Watch WiFi → local Nextcloud | 1-5 MB/s | Fast local downloads |
| Watch WiFi → remote Nextcloud | 0.5-3 MB/s | Internet-dependent |
| Watch via Bluetooth → phone → internet → Nextcloud | 0.1-0.5 MB/s | Very slow, last resort |
For meaningful transfers: Use direct WiFi. Bluetooth-bridged internet is functional but painfully slow for anything larger than a few hundred KB.
Practical file sizes
| Content | Size | Watch WiFi time | Bluetooth bridge time |
|---|---|---|---|
| Reference image | 200 KB | Instant | 1-2 sec |
| Podcast episode | 40 MB | 8-40 sec | 80-400 sec |
| Music track | 5 MB | 1-5 sec | 10-50 sec |
| Watch face APK | 5 MB | 1-5 sec | 10-50 sec |
| Short audio book chapter | 20 MB | 4-20 sec | 40-200 sec |
Download vs. stream
Always download on watch WebDAV. Streaming requires persistent connection and works poorly given watch WiFi instability. Download the file → use it offline.
Battery Impact
WebDAV usage on watch:
- WiFi activation: primary power cost
- HTTPS encryption: minor additional CPU load vs. plain HTTP
- File download: proportional to transfer duration
- Total for a quick download session: 3-5% battery
Recommendation: Do WebDAV transfers when watch is freshly charged or on charger. Don't drain precious battery on lengthy browsing sessions.
Server-Side Optimization for Watch
Create a watch-friendly folder
On your Nextcloud, organize watch-destined content:
/Watch-Sync/
├── Podcasts/
│ ├── Latest-Episode.mp3
│ └── Previous-Episode.mp3
├── Music/
│ ├── Running-Playlist.mp3
│ └── Cool-Down.mp3
└── Reference/
├── QR-Codes/
└── Quick-Images/
Principles:
- Flat hierarchy (2 levels max)
- Clear filenames readable on tiny screen
- Only content destined for watch
- Keep each folder under 20 files for comfortable scrolling
Automation with Nextcloud
Server-side features that help:
- Flow/automation: Automatically move latest podcast to Watch-Sync folder
- External storage: Mount other sources into Nextcloud accessible via WebDAV
- Sharing: Receive files shared by others into your Watch-Sync folder
WebDAV vs. Other Watch Access Methods
| Method | Works outside home? | Speed | Security | Setup complexity |
|---|---|---|---|---|
| WebDAV/Nextcloud | ✅ Yes | Good | HTTPS encrypted | Medium (URL entry) |
| FTP | ❌ Home only (no VPN) | Good | Unencrypted | Low |
| SMB | ❌ Home only | Best | Varies | Low |
| WiFi Share (phone) | ✅ (phone nearby) | Good | Local only | Very low |
| Google Drive | ✅ Yes | Good | Google HTTPS | Low |
| Dropbox | ✅ Yes | Good | Dropbox HTTPS | Low |
WebDAV wins when: You want self-hosted cloud access from anywhere, without trusting third parties with your data.
Security on Watch
App passwords (recommended)
Don't use your main Nextcloud password on the watch:
- Nextcloud → Settings → Security → App passwords
- Create "Wear OS Watch" app password
- Use this in AnExplorer
- If watch is lost/stolen: revoke only this password
- Main account unaffected
Certificate trust
If your Nextcloud uses Let's Encrypt (standard): certificate is trusted automatically. If self-signed: you'll need to accept the certificate on first connection.
Watch loss scenario
If your watch is lost with saved WebDAV credentials:
- Immediately revoke the app password on Nextcloud (from web or other device)
- Access terminated — lost watch can't reach your files
- No impact on other devices using different app passwords
Limitations
Tiny screen browsing: Large Nextcloud libraries are impractical to browse on a watch. Know your file paths; navigate directly to known locations.
URL entry pain: The initial setup requires typing a complex URL on a watch keyboard. Do this once — save the bookmark.
No auto-sync: Downloads are manual. No background synchronization of files.
WiFi dependency: WebDAV needs network. No WiFi = no access. Download what you need while connected.
Transfer interruptions: Watch WiFi can be flaky. If a download fails, retry. Resume support helps for larger files.
