I run weewx with the Belchertown skin and a couple of other skins, with a mysql 
database; there’s a local nginx instance running but the pages are uploaded to 
a hosted server that gets most of the traffic.  This configuration was tight on 
an RPi 1B+ with 512MB — every few months it would run out of memory and need a 
restart.  It runs fine on a 3B+ w/1GB.
