Default-Calendar and MMM-Calendar-Ext2 with CalDAV from NextCloud?

[do1mps]

Hello Forum,

i did my first initial Setup of MM2 a few days before, and got it all running very fast.
Thanks a lot for the much work, MM2-Creators and Community. Youre top!

But with one synch i do have my complications, and i hope some of you have a idea how to deal with this.

I tried the original Calendar-Module and the MMM-Calendar-EXT2, but both of them do have his problems getting the NextCloud (=owncloud) caldav Calendar.
Two other calendars i have successfully bound to MM2 works fine, but my own “nextcloud”-Calendar not.

Lets describe what i had done:
The configuration looks like this:

{
    symbol: "calendar",
    url: "https://nc.[url].de/remote.php/dav/calendars/[user]/personal/",
    auth: {
        user: '[user]',
        pass: '[password]',
        method: 'basic'
    }
},

This is impossible, there are items in this Calendar. So i tried MMM-Calendar-Ext2

So I am going around checking the forum and playing a while with cURL to check what is going on. It seems the NextClound|OwnCloud do something else which is not just ical, it is caldav with every schedule in one separated ical-File. So the XML i got is a summarize of a “directory” showing the ical-“Files” for this calendar:

pi@magicmirror01:~# curl -i -X PROPFIND https://[user]:[password]@nc.[url].de/remote.php/dav/calendars/[user]/personal/ --upload-file - -H "Depth: 1" <<end

Dear Team, do you see any possibility to parse these XML, get the found ics files and publish this as calendar-Items to the MM2-Calendar-System?

Thanks a lot!
Stefan

It seems XML is a bit tricky in this Forum. I am on it to make it visible to you…

@do1mps
the calendar reader expects ics format. others have been able to download ics file ( into module folder) and point config to the downloaded file
