Well, I have to say that whatever you changed appears to be doing the trick. I've had Cumulus running just as much as I had done previously, and so far I have not seen a single piece of erroneous data transmitted for wind speed. I've had a few calm evenings here too, and it seems to be spot on now!! If I see any different I'll let you know, but as it stands, it may well be that you've nipped this bug in the bud! Thanks very much.
