I suspect there is some history involved. As far as I can make out, if LOOP2 data were to be read then the packets are alternated with LOOP - which would result in LOOP packets being received every 5 seconds instead of every 2.5 seconds - perhaps that is why they are not being read!!! As to whether they should or should not be why not make a posting on the development group!!
What I mean was that dewpoint and heatindex and other items which are actually in LOOP2 packets I believe are software generated in weewx, and not read from the station.
