Ok, so I had a bit of spare time and was able to fix it. I’ve patched a tst container (copy from my active HA container) with python-caldav v0.9.0 and the issue discussed here was resolved, unfortunately I ran into another error, this one:. https://github.com/sabre-io/Baikal/issues/982

Luckily I was able to fix it with this solution on the Baikal config: https://github.com/sabre-io/dav/issues/1318#issuecomment-757380175

So now I have a tst environment where the fix(es) were successfully applied. Now (probably tomorrow) time to check how to create the PR for python-caldav v0.9.0 🙂

So it took a while, bit it looks like it is resolved (until the next HA version)

@allenporter Hey Allen, I am seeing that You’re active in improving the Calendar integration. Would it be possible for You to include the newer python-caldav version of tobixen into HA?

I got busy with guests previous weekend, but I’m working on running tests for the caldav library now and will release 0.9 this weekend 😃

First I have to release 0.9. Then it has to be picked up by the HA-team. Then we have to wait for a release of HA. But I promise, I’ll do everything I can to have 0.9 released before or during the weekend.
