Unable to setup Caldav

Configuration
1

Hi All,

Saw in the latest release that caldav support was added so I thought I’d give it a whirl as I’ve been using a Caldav server with Mozilla Thunderbird as a client for a number of years. So far I have’t had any luck getting it to work by following the guide here: https://home-assistant.io/components/calendar.caldav/

Here’s the relevant bits from my log:

and my config file:
calendar:

  • platform: caldav
    url: http://< servername >:1080/users/< username >/calendar
    username: < username >
    password: < password >

really appreciate any suggestions.
Cheers!

Probably not the problem, but you don’t specify a host in your URL, just a port number (1080).

3

Sorry, I pulled the hostname, username and password out of the config to sanitize it, they way I had formatted them the website didn’t display. I do have them present in the actual config.

Thanks for catching that though, edited the post for clarity.

4

This is a known problem that will be fixed in 0.60.1

5

OK cool! Thanks for the note. I’ll wait for the 0.60.1 release.

Cheers!

I’ve updated to the 0.61 release but am still having issues with CalDav. The following is my error log (using same config as before):

Its working fine for me. It looks like its failing on the hostname. Do you still have that port in the url?

8

Thanks for the reply, I do still have the port, is there a better way of specifying a non-default port?

9

I just tried adding a port number to my url, and it didn’t complain, which rules that out as the problem. I’m not sure what else to try.

The only thing different in my configuration is that I have a list of 1 calendar. It is supposed to be optional, but that could be a mistake

calendar:
  - platform: caldav
    url: !secret owndrive_url
    username: !secret owndrive_username
    password: !secret owndrive_password
    calendars:
      - Waste
