Hi Steve , I'm wondering if the values displayed with the tags <#RecentOutsideTemp h=6>
<#RecentOutsideTemp h=5 m30> andso-on dislay the 'good values' it seems to me that to values in a hour are allways the same, I know it's an approach but my data are witten to the logfiles every 10 minutes and have more changes as displayed.

I've made a table and substract the values to a graph

http://apeldoorn.tk/weer/googletrend.html (these trends are not upto date due bufffering of the googleserver but represent the data in the range) I can't give a timetag with the values as suggested by someone else this isn't a priority for me by the way. Any suggestions how I can prove the historical data ??

I created a test page: http://sanday.org.uk/weather/test.htm

At 10:00 local, this shows:

Time now = 10:00 on 16 April 2012
Temp now = 6.8
<#RecentOutsideTemp m=30> = 6.4
<#RecentOutsideTemp h=1> = 6.0
<#RecentOutsideTemp h=1 m=30> = 4.4
<#RecentOutsideTemp h=2> = 3.7
<#RecentOutsideTemp h=2 m=30> = 4.2
<#RecentOutsideTemp h=3> = 3.6
<#RecentOutsideTemp h=3 m=30> = 1.7
<#RecentOutsideTemp h=4> = 0.9
<#RecentOutsideTemp h=4 m=30> = 1.3
<#RecentOutsideTemp h=5> = 2.3
<#RecentOutsideTemp h=5 m=30> = 2.8
<#RecentOutsideTemp h=6> = 2.6

I'm not sure exactly how the search works; you might find that it finds the nearest entry after the time you specify, so if the data is from the logs rather than the 1-minute live data, you might find a slight 'shift' to the returned values.
