A new third party IP logger (WiFiLogger) has recently become available for
the Vantage Pro series. It has received rave reviews from users and
apparently behaves in most ways like a superset of the Davis WeatherLink IP
logger. With a little difficulty (not weewx or hardware problems), I have
installed one of the new loggers in my VP2 (previously communicating with
weewx, running on a RPi, without problems via a USB connection) and (I
think!) I have made the appropriate changes in weewx.conf as if the new
logger were an instance of the Weatherlink IP. It seems to be happily
downloading and storing archive records, but it is consistently erroring
out on LOOP records. The relevant section of my weewx.conf file is:
[Vantage]

It almost looks as if weewx is still trying to get the LOOP records from
the (virtual) serial port.
Can anyone who is using weewx with a VP2, either via a Weatherlink IP or
via a new WiFiLogger, shed any light on this?
