Synology DSM

Synchronize contacts, events and tasks between Synology DSM and your Android device using DAVdroid!

Synology DiskStation Manager (DSM) is a Linux based software package that is the operating system for Synology's DiskStation and RackStation products.

A CalDAV server is available in the base system. CardDAV can be installed as an extra package.

It's also possible to run other CalDAV/CardDAV software like Baïkal and ownCloud on Synology systems. In this case, see the respective configuration pages for details.

CalDAV setup (using Synology Calendar package)

The Calendar package provides a calendar with Web and CalDAV interface.

You can view the CalDAV URL in the Calendar Web interface (Calendar > CalDAV Account). Use the macOS / iOS URL, but you have to replace /caldav/ by /caldav.php/ (Synology bug, not a DAVdroid bug).

So, the CalDAV URL could look like this:

CalDAV setup (using Synology WebDAV package)

See: How to host a calendar server using the Synology NAS (Synology KB)

  1. Open Synology DSM: Control Panel / WebDAV.
  2. Enable WebDAV or WebDAV HTTPS (remember the port).
  3. Enable CalDAV.
  4. Go to "View calendar list" and add a calendar. Make sure that you have read/write permissions on the destination folder.
  5. In the calendar list, each calendar has a location (e.g. MyFolder/Work). This location is required to add the calendar with DAVdroid.

Now you can add an account in DAVdroid:

CalDAV URL: http(s)://server.example:port/MyFolder

User name and password: same as for Synology DSM

Known problems

CardDAV setup
