Are you using 'spike removal'? EWtempdiff in cumulus.ini in 1.9.0., or on the calibration screen in 1.9.1?m0clx wrote:Hi - had the temperature error thing yesterday again. Data ok in logger but cumulus insisting outside temp flat-lined all day.

Re: Fine Offset Station data errors
Hi Steve
yup, think so 1° I think. I have attached the two graphs for comparison. It was cold in the night and warmed up really quickly so I guess it tipped the threshold of the spike filtering.
Maybe I should increase the spike removal threshold. I used to get spikes at high windspeeds I think. I might try unpluging the wind sensors for a while with the spike removal off see if I can locate the prob.

Yes, it looks like the spike removal setting causing the flat-lining, as it picked up again once the temperature had fallen again to within a degree of where it had been when the flat-lining started.

Re: Fine Offset Station data errors
Thanks Steve
I've set the ewtempdiff to 2 degrees. Hopefully it'll be less likely to be triggered under normal conditions then. I think the spikes I got were very large when they occured (I use orignal cable but a longer mast).
Will see how it goes..
cheers
