Don't worry about the anomonaly !
You are looking at the last data from the wx, NOT the last (5 min) record

Doesn't seem to be 'carrying around' Min / Max nor change / trends

But .......... It may be 'carrying around' rain totals

beteljuices thoughts #2

1/ Record No.
2/ date / timestamp (ISO format) of when Software interogated wx
3/ date / timestamp (ISO format) of RECORD
4/ probably recording interval (minutes)
5/ indoor humidity
6/ indoor temp. (is this always C or user set ?)
7/ outdoor humidity
8/ outdoor temp. (is this always C or user set ?)
9/ Dew Point (is this always C or user set ?)
10/ Windchill (is this always C or user set ?)
11/ baro - absolute (is this always hPa or user set ?)
12/ baro - relative (is this always hPa or user set ?)
13/ windspeed - appears to be metres per sec
14/ ? windspeed - may be beaufort
15/ windspeed GUST - appears to be metres per sec
16/ ? windspeed GUST - may be beaufort
17/ wind direction: 0 - 15 options 8 = S(outh)
18/ wind direction: NNW - probably language dependent
19/ ? eg. 0 - integer
20/ ? eg. 0.0 - 1 dec place
21/ ? eg. 0.0 - 1 dec place
22/ hourly rain - appears to be mm
23/ 24hr rain - appears to be mm
24/ ? may be 7 day rain (mm ?)
25/ ? may be rain month(? this or 30 days)(mm ?)
26/ ? may be rain total (mm ?)
27 => 34/ ? eg. 0 - integer


Any ideas on the blanks ?, what 'fields' do you have when you look at historic records with the software ?
