Hi Graham Thanks for that and I understand all of what you are saying - except I have no idea whereabouts in /etc/init.d/weewx to change to make it use Python3. I thought I might find the line command line containing weewxd in there somewhere but alas no (or I've done a "boy look"). And I know enough this part of the system to be dangerous, so I'll keep fingers off until I can actually figure this out! Still learning lots here so appreciate the patience and explanations :)
