Error while setting up

[jgclark]

I'm yet to get this sensor to work. I'm getting this error:

There seems to be a problem with the URL you are using for the calendar.

There seems to be a problem with the URL you are using for the calendar.

Thanks for replying. I've deleted and reinstalled the extension, and again put in the URL from Apple Calendar. Same errors. Is there anything else that can be done to debug this?

[Olen]

I don't have a mac or an apple calendar, but are you sure you use the whole URL?

https://discussions.apple.com/thread/5950029

[jgclark]

Here is one of the calendar URLs I tried: webcal://p65-caldav.icloud.com/published/2/OTg2Mjk1NzU5ODYyOTU3NQAXMSn9W9Pe7p5qwCiF_ulzmhD6zxHT625jIDZ_qXx0XvdmqECZZN64V9bB3Mu05K8MtKJuTEsraWZlqto4QyE

[Olen]

Change the URL from webcal:// to http://

I've deleted and redownloaded again. This time I get the following error:

This is a different set of issues than before.

I'm running on same versions as given in my OP.

[Olen]

I don't think you need to redownload all the time. Just try to remove the calendar and add it again. Not sure if Apple requres http or https, you can try them both.

[jgclark]

Thanks. Am trying various versions of the URLS. But that latest error message looks to me like a more fundamental problem than my configuration.

[Olen]

I just checked the calendar url you posted a few days ago, and as far as I can see that calendar is empty.

We should probably add some checks for that as well, but currently we probably just expect that the calendars have some events in them,

[jgclark]

I thought I'd try again with HA 2022.4. I'm still getting the same errors quoted above. This time I went into the console and had a poke around. And I have found I have no /usr/local/lib/python3.9/ folder, so perhaps no surprise it's not working. I don't know enough about HA and HACS to know what to do to resolve this. FYI I started with HA with the last release of version 2021.

[Olen]

It has nothing to do with any of that. The error basically tells you that there was no valid entries found in the calendar URL you provided.

I just tested with the URL you provided earlier again now, and by replacing "webcal://" with "https://" the calendard was parsed fine here.

[jgclark]

Thank you for persevering with me on this, @Olen.

It has nothing to do with any of that.

OK, I trust you on this.

I've tried deleting the integration, and then adding two different calendars, one as above, but both starting https:// not webcal://. Both reported success. The config checker says all is well. I restart HA. Again I see no entries in the calendar view, but I see the same error as before in the log:
