Wacky rain amounts on PWS
« on: September 17, 2011, 05:50:45 PM »
I installed my Davis Rain Collector interfaced with a Hobby Boards dual counter board to my One-Wire Weather setup.

Since I changed the rain gauge from the old Dallas Semiconductor one, I have been getting extreme rain counts (only on PWS Weather) like

Precip    Precip Rate    Daily Precip Total
999.99 in    0.00 in/hr    24999.75 in

The daily precip total will jump by 10,000 right after going to zero. Sometimes it looks OK, especially during actual rain. When there is no rain it starts going nuts.

The odd thing is that my local program display is fine, a remote PC getting the same data is OK. Wunderground and CWOP rain amounts are OK as well. (no rain, it stays at 0.00 inch like it should).

I have dumped out the log file and there is no sign of any problem with crazy counts there either.

I am kind of stumped by this. Has anyone experienced any similar issues?


----------------------------------------------------------------------
I checked my posted data for PWS at http://www.pwsweather.com/pwsupdate/pwsupdate.php?ID=CW4114
I discovered that the Software Version and DailyRainIN columns are reversed. PWS must be parsing Oww/0.82.2-L as rain data.
Perhaps it is just a coincidence with the new rain gauge?

Just to put some closure on this, I found that this issue was the result of posting the PWS data from a remote client instead of the Linux box actually running the weather station and rain gauge. I did this because I had graphics issues with the newer version that the display of OWW wouldn't render correctly. I since found that I was missing libraries and corrected the problem on the host machine with OWW 0.84.0. Running the PWS uploads directly from the host weather Linux box resolves this precipitation data issue.
