Thanks Michael I've worked through the doc but not found a resolution.
pi the weewx user is in the following groups pi adm dialout cdrom sudo
audio video plugdev games users input netdev lpadmin gpio i2c spi
The arm device is as follows;
(weewx-venv) pi@weepi:/home/weewx $ ls -l /dev/ttyAMA0
crw-rw---- 1 root dialout 204, 64 Jun 24 11:10 /dev/ttyAMA0
ps -ef | grep weewx - shows no instances running
If I sudo weewxd then it runs.
when running with sudo I see an error "unrecognised magic number 5528" in
the log
