Just installed Weewx 5 and new install of Bookworm 32 bit on Raspberry pi
4. I'm using a USB Serial interface with my Davis Vantage Vue, which has
worked perfectly for the past few years.
After completing setup I started with sudo service weewx start.
No data appeared to be sent, so checked weewx status and got this error:
$ sudo service weewx status

Something has changed with permissions I think, but no idea what.
Any ideas on what has happened? Thanks!
