Vince, thank you for your reply. The os has not been updated since I installed weewx Versio 3.8.0 which is still the version in use. The system worked perfectly for 10 years but has now become very unstable. Sometimes I get a week without issues. Yesterday I had to shutdown and restart on 3 seperate occasions. Hence my "where do I start" question. I tried a new SD card but this has not resolved the instability.
My questions remain the same, where (how) should I start to try and isolate the issue.
