I’m trying to de-Google my life and self-host more. One tricky point with me is calendaring. I can get a CalDav server running and syncing with my Android phone without much hassle, but I haven’t yet found a server or client that can send e-mail reminders for events, rather than just pop-up notifications.
I’ve been told to try Nextcloud. I tried installing it but it’s overkill for me, and I don’t want to deal with setting up a domain. Surely there can’t be exactly one CalDav option that can send email reminders. But I’ve never heard anyone say anything other than “Nextcloud.”
My raw IP wouldn’t help, my ISP has me behind CGNAT. I can set up a CalDav server and sync it with Tailscale, but can’t do that for Nextcloud.
You can bypass CGNAT easily. Look here. I sync contacts, calender, tasks, everything from Nextcloud.
Why can’t you sync NC over Tailscale?
