Virtual VP

Hi, I have just been trying out Virtual VP, and it seems to have changed the way Cumulus is plotting it's graphs.
I attach my wind graph :

I plot the peak gust rather than use the option "plot latest gust", so none of my settings have changed.

I think I know what's happening, it seems Virtual VP is feeding in data to cumulus more often than the data updates. Because during the period between 'real console updates', I see the average windspeed and average bearing changing. Hmmm...

Have you changed VP2SleepInterval?

Good thinking Steve, it never crossed my mind!

I'll change to VP2SleepInterval = 1100 as suggested in Wiki. Thanks

My Fujitsu Lifebook's HD failed yesterday so I decided it was time for a new laptop to run my Davis VP2. I downloaded the latest Cumulus version 1.8.9 and installed onto the new Toshiba and discovered the wind graphs were looking very chunky like in the image above, with the gust peaks lasting 10 minutes, something that was not happening previously. I did not need "VP2SleepInterval = 1100" on the Lifebook, but have just included that line in the .ini file now.
I'll know if it made any difference shortly.

No, that didnt help at all, the wind display is still very chunky. What else could it be? I have changed the "calculate 10 min average" and "use speed for average calculation" boxes, but that made no difference. What else might be causing the chunky display? The temerature and other graphs seem good, its just the wind that is chunky.

TIA, Gordon

If you want to change that, you probably need the 'plot latest gust' setting in the display settings.

Are you using Virtual VP?
