Ambient weather data
« on: August 09, 2018, 11:11:19 AM »
Hi, I am a rank newbie at WD and have been playing over the last 3 days trying to absorb this great program and how it works.  I have an Ambient 2902A.  What I am noticing is a discrepancy in rain data if I close the program, i.e. I got a new build of windows 10 and it took about an hour to install.  When I restarted the program daily rain jumped from the correct .300 inches to .720 inches.  I have figured out how to correct yesterdays rain, the month total and YTD total, but, why did this happen in the first place? I am attaching a screen shot of the graph, notice the red rain line at around 17:30 hours, I went out during a thunderstorm and shut off the computer, it jumps when I come back, again at 23:00 when I installed the new windows build.

I get the blue line, being humidity from my nest thermostat not being read, stored or saved while WD is not running.

Thanks for any help on this.

Hi
are you using build 77?
re the rain problem
try that version

re the humidity from your nest
there is no way to get data from when the program is not running

Nice, thanks.  I am an old beta-tester (done MS windows since 1994), so leave it to me to find a bug.  Thanks for your help and i love the program.  I am still only a couple days into the trial period, but i will be happy to support your efforts and buy the program.  Its obviously the result of a lot of effort and nicely done.

Ooops, still not quite right, did it again last night after the new build was installed. Doubled the daily total for rain fall.  Perhaps you are getting the max hourly rain instead of total rain?

what looks to be happening is that the current total rain is added on to the already stored total rain that WD had
in theory I found where in the code that was happening and it should have been fixed
but what I will do is plug in some dummy rain amounts into the raw data and test and get back to you
(I am guessing because its summer time not many users have come across this problem yet)

If there is a way for me to store the actual data and forward it to you? i'd be happy to.  I have watched it read in the downloaded data from ambient when its been off over night and its neat the way its scanning the time stamps looking for when it shutdown.  Since we are only looking for the incremental changes, perhaps its only subtracting the base amount on the first new data line, but not storing the new baseline for the second data line?  Just a thought, i haven't coded in many years, but remember well the head scratching moments of 'why did it do that?'

Lucky me to live in the land of daily thunderstorms. We had more rain in the last 3 days of July than is normal for the whole month and August's total is already 2x the monthly average.

 :D

I did try and do some testing with some 'offline data'
by changing the rain values in the history data and live data
but I could not duplicate a problem
but I have added option to use the rain totals from the station
in the ambient weather station type setup

so that should work better in theory
latest .zip update (build 79 )

So, naturally, it has not rained since we had this exchange, its supposed to rain today.  But I notice a different anomaly started with the new tick box for "use station rain total."  Every day either at 23:17 or 23:32 the temp is read to have dropped to 32, the humidity to 0 (actually the number disappears altogether), and the dew point goes to 122.  Two screen caps attached.  Its not in the raw ambient data that way.  It also is not being picked up by 'daily extremes' and shows no where except the graph.  Its not really a big deal to me, but thought i'd let you know its happening.  Also, the app is not running, it happening upon read in of the overnight data.

ah
its not related to the new rain setting
but is a first time initialisation of the data when using the history data function
I should be able to resolve that
(actually if you could email or PM me your apikey so I can test with your data)

The graphing issue is, indeed repaired, thanks.  We finally got some rain and what i notice is that the rain rate and max rain rates are never non-zero.  This is something new, as it was working the last time it rained.  You can see in the screen cap the ambient web page behind the WD display showing that it is raining.  The totals and all increment fine, but the rates are always zero.

You are very attentive to these things and it is appreciated.

that will occur if you have set to use the station's rain totals
what I need to do is use the rain rate provided by the station then
I will do that
( I see that hourly rain data is provided)
