Contacts and calendars sync without a server (Syncthing + Radicale)

I just use Syncthing to backup Radicale files. I guess this is to remove the need for a domain name and web server? This won't work with all devices like iphones. Also shared calendars won't sync properly.

I am using this setup for years by now. Works great mostly.

Its great, been using it for a while across a few different devices. Android/windows/Linux, it doesn't care.

Isn't that just overcomplicating things for no reason? Radicale provides WebDAV endpoints that clients (including DAVx5 on Android) can just connect to, to synchronize calendars and contacts. All of this setup seems to just do all the sync part manually through Syncthing rather than just use Radicale's built-in functionality.

I'll try this! I used to use caldav via my mail provider with DAVx5, but I had problems with it not retaining notification settings with recurring events.

I don't know if that's a problem with their caldav server, DAVx5, or my phone's calendar. But worth trying with radicale and see if it works.
