Understand that weewx does not read LOOP2 packets. Did not get the part about " LOOP2 data is more than likely software generated by weewx"
The LOOP2 packet format is specified in Davis protocol and it seems to be containing some data that WU is expecting. Shouldnt weewx be reading it then? Not sure if something changed in WU upload protocol as well. The earlier wiki link with upload protocol no longer works! So I am not sure what the protocol was before.
