Re: davis rain
Haven't followed all the rain determination from the attachment but it says:
2016-04-07 18:43:06.384 Station type: Davis Vantage Pro2
but you mention:
ive got the davis vantage vue
Do you have the correct station ticked in setting?

Ah, OK... I wasn't at my computer to check what setting options there are, and I couldn't remember either.

Re: davis rain
Sorry I am unable to understand all the rain amounts in that log. I did notice entries of "rainday start" = 50.2 and "raincounter" = 51.8 along with some other "startup" rain amounts. Again sorry I can't help with this.
However I did notice an entry:

However I did notice an entry:
You may want to look in your Mar16log.txt file at line 42802 and see if you can detect an error there.2016-04-07 18:43:56.032 Error at line 42802 of data/Mar16log.txt : startIndex + length cannot exceed length of string.
Parameter name: length
2016-04-07 18:43:56.033 Please edit the file to correct the error

Re: davis rain
Looking at the error message in the previous post, I reckon there is either an extra comma on that line, or two lines have been joined together by deletion of a line ending. If you upload your data file to here then somebody could take a look - more than one pair of eyes often leads to quicker solutionsdazza1223 wrote:hi i look in that line 42802 and it dose all seem to be ok this is relly burging me lol
