Weather Display and Meteotemplate API Rain Rate issue
« on: May 29, 2017, 08:19:27 AM »
Hi Brian,
I use Weather Display to pickup data from the Davis Vantage Pro2 and use the meteotemplate API to send to meteotemplate.
This is working fine an all respects except the rain rate.
This is shown OK on the WD control panel but Meteotemplate see a RR number that is far too low.
It was reading approx 3mm/hour in WD but this mapped to 0.1 or 0.2mm/hour in meteotemplate. The actual rain amount was also correct.
This could be a setup issue on my part but I have also asked Jachym and he wants to check that RR from WD is being sent in mm/hour via the API.
I am using WD 10.37S Build 44 with latest build of meteotemplate
Any help would be greatly appreciated.
Justin

I would first be using the latest version of WD as I might have already fixed this (as I am not seeing other reports of this issue, as the latest version does use per hour)

Hi,
yes, it should be the average over the API sending interval.

However Justin's values are way too low, I think he might be using old version of WD, I remember this was a problem at the beginning, which is now fixed.

I have now updated to the latest WD version (build 49). The reason I didn't upgrade was because I didn't see anything on the changelog that appeared relevant.
Now I will wait for the rain which looks like it may be some time away :-(
Thanks

There is an analogy with buses and police here.
There is never any when you want it and when you don't it is relentless   :x

OK - there is still something wrong with this.
The Rain Rate as shown on WD control Panel (both the mm/minute and mm/hour) has very little correlation to the API RR info being sent to meteotemplate which is normally zero. On occasions it sends a one off high reading (probably correct) but then returns to zero on the next reading. The daily rain reading is perfect.
I am using the meteotemplate apiViewer to check values that WD sends

OK lets see what Brian says, the numbers you see in API viewer come directly from the raw data file saved from the API bypassing the db etc.

It is quite possible that I have not setup something correctly in WD for my Davis Vantage Pro2 as I am very new to WD, however the WD app display does appear to show the correct values as far as I can tell.

Hi Brian,
The frequency of the data as set in WD is every 5 seconds.
Thanks

try this update
http://www.weather-display.com/downloadfiles/weatherdisplaytest.zip
which now provides the rain rate as a rolling 1 minute average
