The Tasmota firmware documentation has a decent list, but it's limited to devices that are known to be flash-able so you can install custom firmware on them. https://templates.blakadder.com/
Are you thinking of Lemmy? OP had it on their Matrix chat server.
At least your stupid ISP has IPv6. Mine doesn't (yet).
I'm the one who files the most bug reports on github under a different name. Our instance runs on Lemmy Schedule, so thanks!
I used Portainer for a while and still like it for checking out networking stuff, but try out Dockge! It's more open sourcey and basic, but makes updating easier.
It's great. You can subscribe to all sorts of stuff including Lemmy communities if you want. You just have to be a little nerdy to get it set up.
I used to use Google Feeds (I think that's what it was called?) until they shut it down. Then I switched to Feedly. I think both of those had some "discovery" functionality so normal people could just search for something and follow it. You have to find your own RSS feeds with FreshRSS but it's still great. I use Read You as an Android app.
Have you ever heard the phrase "don't dip the pen in company ink"?
I use gmail. You just have to set up an "app" password. I always have to search for how to do that, but once you have an app password you're off and running.
I also just started hosting my own nfty and have been moving as much as possible to that. So far I've replaced two email notifications with push notifications, which is nice.
The Google account is still there, I've just hidden each of those calendars. New events seem to default to whichever calendar you used last (citation needed) so once you've created an event under the NextCloud account, it should default to that. The app I use (Business Calendar Pro) doesn't even give the option if a particular calendar is disabled.
As far as DAVx^5^, the default is to only sync every 4 hours. Phone to NC is instant (once DAVx sees the change), but NC to Phone has a delay. However!...
I just set up the ntfy app to create instant two way sync both ways. It's pretty slick. Dig around in the DAVx^5^ documentation about how that works. You install the DAV Push app on the NC server, ntfy on your phone, enable UnifiedPush in the DAVx settings, do a little dance, and then NC notifies DAVx every time there's a change.
Edit: you can also delete calendars from Google Calendar settings on the web, but this is obviously permanent. I think you can also totally remove Calendar from your account.
Edit2: You can't remove calendar from your account, only delete individual calendars.
In a web browser I use the NextCloud one. It's functionally very similar to Google and I like it a lot.
For our Android phones, my wife uses the Google Calendar app, and I like Business Calendar Pro.
Both apps you just have to go into the settings once DAVx^5^ has done the initial sync and uncheck all of the Google calendars so they aren't shown, and check the boxes next to the new Calendars.
Exporting and Importing I could only really easily do via the web browser for both.
