Cumulus Support

Hello, this thread was pertaining to my question so I thought I could piggyback off of it...

I just moved to the Davis 6313 console, everything is running well now except for the graph of my wind speed (the gust is fine) when cumulus downloads the historical data, everything is good, the wind data matches what it should be on weatherlink.com. But after cumulus has been running the windspeed drops dramatically, say the windspeed is 3.4mph, cumulus would report the wind speed as 0.4-0.5mph.

I find it interesting cumulus downloads the historical data just fine, but after its running the windspeed is much lower than it should be.

I have messed with the common options and the advance options, but after clicking the average boxes in different variations of on or off, the windspeed flatlines.

When I restart the program no matter what I had last saved the setting as, the average cumulus speed box is always checked.

Please switch on debug and data logging, let MX run for a while and post the resulting log file.

Hello, let me know if I'm missing anything you need...


I took a screenshot, the data to the left of the calm period is accurate data, the windspeed to the right was ran while cumulusmx was live, so its the erroneous data.

Your MXdiags at startup shows: and no indication it was turned on later.

Paul, ah, must be because I didnt restart cumulus, ill let it run until tomorrow afternoon and see whats up

Hi,
A short period i.e. 15 to 30 minutes should be fine, and the monthly log file that includes that logging period.

Enjoy,
Paul

If you switch them on they should start without a restart. It is more likely that you did not Save the settings after switching them on, because if you do not do that they will not start.

I did save the changes, when I rebooted it, the two boxes were checked

Here is what I have

OK, it's a problem in Cumulus. It is always calculating the average wind speed (ignoring the advanced settings), but there just isn't enough data available when using the cloud as a source. I'll change it to use the average speed value from the cloud.

Great, thanks for the help

Mark,

I updated cumulus to the newest build and the windspeed now works great! But the wind gust goes from my preset 1 minute setting to, it appears, 10 minute gust speed. Is there something I can do to fix it?

No, 'fraid not. The data points are 5 minutes apart, so there is no way of MX calculating a 1 minute value - and Davis only send a 10 minute value via the wl.com API.

I guess if you had a Pro+ subscription it might change slightly, but I think you would still only get a 10 value from Davis.

For realtime data you need a WLL (or an old console + logger)
