Rainfall reading accuracy

Hi
I have Davies Vantage Vue station and Cumulus MX 3040 build on rasp pi 2. Yesterday the console rainfall reading was reading 20mm at 23.00h but Cumulus 13.2mm. I have further investigated this morning and logfiles /dayfiles suggest 13.2mm. But Weathercloud website (I upload data to them) says 20mm for yesterday. The met office WOW site shows 13.2mm.

Although it was very misty and drizzly yesterday, I cannot remember 20mm falling from the skies when I was awake. We had 39mm on the 1st of August though.

The console monthly total has added the 39 and the 20. Anybody any thoughts? There does not appear to be any break in transmission.

David

If you zip up the MXdiags folder and attach it, I'll take a look at the figures that Cumulus was working with - it uses the increasing annual total to determine daily rainfall etc.
