I’m looking for ways to reduce my dependence on the cloud, and one obvious target is Google calendar.
I’m able to host my own calendar on a Synology NAS, and HA can access this using the the CalDAV integration, but I notice that the docs and the GUI refer to it as using the cloud.
Is this actually the case where the server is on the local network? I wouldn’t have thought so - unless there’s something going on behind the scenes.
