Hi

Results for August - some very spurious RG11 readings on the Cumulus RG11 at the end of the month. My first though was birds perching on the unit but the select-a-graph shows the readings occur when there is rain - birds would be much more random.
The two buckets performed quite well. The dummy reading and two other red entries used the manual gauge reading due to instrument or computer hiccups

My numbers were so different between the two RG-11's sitting only maybe 24 inches from each; I quit looking. The odd thing is that the Davis and the Dallas tipping bucket are also adjacent to each other on the same weather mast and these two tipping buckets were always in sync. That said I honestly don't know if I want to use the RG-11 as a digital tipping bucket. Maybe just an on/off switch for a rain sensor.

My conclusion too. At least now if the RG11 development / accuracy continues, Cumulus has the ability to read the data from it :) .

Hi All
I thought it had gone quiet on the RG11 front but it seems I'm not the only on still playing with the things.

So here are my results from September.
The manual site RG11 is still modified with the funnel and an extra tipping bucket has been added. A very well made mini weather station from Lidl - not PC loadable - only stand alone. At £39.99 with wireless wind and rain sensors incredible value.
That's the one I have called SH Bucket (It's on my summer house roof). The SH Bucket only started during the month so a red 9.3 entry is added to correct the early part of the month. The RG11's are not a million miles out over a period but in the short term very erratic. The red zeroes are when there were no readings. The Sept 31st line is there to give a part reading up to 9am 1/10/2012.

the trend i have noticed is that with light rain the rg11 over measures and heavy rain under measures,

this does fall in line with the info on hydreon's site about accuracy in tip bucket mode.

more readings from other users might help to workout what is going on.
