Totally agree with your comments. I’m trying to handle network and remote server issues for a station I don’t have remote access to, and sometimes (depending on time of year) have to wait a few days before I can go onsite. So I am trying to handle conditions external to WeeWX.
One issue is Raspberry Pi OS “wlan0 carrier lost problem” (see https://www.raspberrypi.org/forums/viewtopic.php?t=233847 for a conversation). Even if I fix each problem as they arise, I’d like to have a “belts & suspenders” backup solution.
