Calendar - connecting to Synology Calendar

Configuration
1

Dear Community,
I’m trying to connect home assistant to my Synology Calendar App - I’m not able to do this ;-(
I set up a calendar at Synology Calendar and shared this calendar.
In Home Assistant I configured the calendar in the configuration.yaml

calendar:
  - platform: caldav
    username: username from user "homeassistant"
    password: password from user "homeassistant"
    url: http://192.168.100.5:5000/caldav/homeassistant
    custom_calendars:
      # CALDAV Synology waste calendar
      - name: "Gelbe Tonne"
        calendar: "Abfallkalender"
        search: "Gelbe Tonne"
      - name: "Restabfalltonne"
        calendar: "Abfallkalender"
        search: "Restabfalltonne"
      - name: "Blaue Tonne"
        calendar: "Abfallkalender"
        search: "Blaue Tonne"

In home assistant the calendar view stays empty after several reboots… grrr.
Anybody out there who has a tipp where Im wrong???

Thanks in advance
//Erik

Any errors in the log?
Sure that your ha server can reach the nas?

Not sure, but if you access this link and want to “access” the other calendars, ypu need to give access to them (via the webinerface).

That’s all I can think of…

I believe it should be caldav.php and closing slash in your calendar URL:

calendar:
  - platform: caldav
    username: username from user "homeassistant"
    password: password from user "homeassistant"
    url: http://192.168.100.5:5000/caldav.php/homeassistant/
    custom_calendars:
      # CALDAV Synology waste calendar
      - name: "Gelbe Tonne"
        calendar: "Abfallkalender"
        search: "Gelbe Tonne"
      - name: "Restabfalltonne"
        calendar: "Abfallkalender"
        search: "Restabfalltonne"
      - name: "Blaue Tonne"
        calendar: "Abfallkalender"
        search: "Blaue Tonne"

Hi. I can’t connect HA calendar to Synology Calendar. I use all yours recommendations, but calendar in HA don’t received calendar data.
