etesync-dav VS vdirsyncer

You can download it and find instructions here: https://github.com/etesync/etesync-dav

That is where I got the package from: linux-amd64-etesync-dav on Github

etebase is an end-to-end encrypted synchronization backend that supports, among other things, tasks. I use etesync for android in conjunction with opentasks on android and etesync-dav as a caldav gateway (synchronized to thunderbird with tbsync and its caldav backend) on the desktop. The backed is rather easy to run as a container image.

There's the official EteSync DAV that works with Thunderbird. :-)

2) install this local bridge server locally on the computer where evolution is installed : https://github.com/etesync/etesync-dav

I am using etesync-dav on Linux. You have to follow this guide https://github.com/etesync/etesync-dav First, make sure etesync-dav works on your OS. Then you have to install the add-ons Tbsync and Dav for Thunderbird and enter your local dav server adress. After restarting the PC the syncing works fine for me.

I'm also using EteSync with the etesync-dav "bridge" for synchronising calendars and contacts (even though, that happens outside of ProtonMail; for me it was more important to have the sync working with Thunderbird and Android devices.

To use the etesync-dav bridge downloads available here: https://github.com/etesync/etesync-dav/releases

Use http://localhost:37358/ for both servers, your EteSync username as the username and the DAV password you got in configuration and running as the password.

Have a look at vdirsyncer. Sync calendars to a local directory and then use eMacs to read them.

I found vdirsyncer which seems like a nice and promising idea similar to maildir which I already use with notmuch, even though it seems too opinionated and the support for Google calender seems largely untested/unsupported.

For getting ics files, have you seen vdirsyncer ?

On another topic, I maintain a tool to synchronise calendars (e.g.: events and todos) using CalDav (a standard HTTP-based protocol which a lot of calendar servers implement). I'm actually rewriting this in Rust full-time these days.

I used https://github.com/pimutils/vdirsyncer and made a cronjob for it on my host. The configuration is pretty simple - but always do a backup before testing! :)

Whatever CalDAV type calendar you go with (NextCloud and Radicale have been suggested here, Sabre/DAV, DAViCal and Baikal are other options), in case you need to sync calendars to it, you might want to look at vdirsyncer. This way, everyone can keep using his favorite app and you can still gather everything in once central place and have it all synced. Or you get everyone to set up DAVx5.

I have recently started organizing my calendars using `vdirsyncer` [vdirsyncer](https://github.com/pimutils/vdirsyncer)

Hm. Generally for folks who are familiar with the command line I suggest using vdirsyncer, a nifty little python program that lets you keep remote calendars in sync.
