I just use the built-in email function that comes with mdadm. If a drive fails, I'll know right away and replace it with a spare. You do need your server to be able to send emails with something like postfix.

It's in the announcement for Plasma 6.1, see https://kde.org/announcements/plasma/6/6.1.0/

To enable it, you need to use the Brightness & Colour widget. See also the merge request for this: https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4093

I guess the documentation is a bit lagging still! I don't know about a list of compatible keyboards, but I suppose you can just try it out to see if it works! 😁
