CWOP dew point data dropping out ** solved **

When I look at the CWOP data analysis page for my station: (http://weather.gladstonefamily.net/site ... =11#themap)

I see the data transmittal for dew point is being dropped for several hours each day and then returns.

Since I'm a relative newbie using Meteohub, which of the log files should I be scanning to find an possible explanation for the data loss ?

Regards,

Which weather station are you using?
Does the temp and hum data for the same sensor also drop out?

I'm using an Oregon WMR-968. The uploads to CWOP do not show loss of temperature and pressure data, only dew point and humidity. I have installed Meteohub v2.6a 3 days ago and I'm currently not experiencing the drop out.

Another anecdotal data point. The data drop appears to only occur when I have added an adjustment factor in Meteohub to calibrate the humidity data. My humidity sensor reports dryer than actual conditions. When the calibration adjustment is active, I get data drops, when no calibration is used, no drops

thanks, that observation helps a lot. I checked code an if the values resulting from a calibration exceed the interval [0..100] then this is taken as a bad value and no humidity values are reported at all.

are there messages according to this in the "meteohub log"?

However, update 2.6b will limit range of calibrated humidity to interval [0..100], so this problem will be solved.

Ive checked the data and your response is correct. Data Loss = humdity >100% due to high actual humdidty plus calibration factor. Looking forward to v2.6+ I love the new WD Live as do my website subscribers. Any chance to get US date formats for the WD live uploads in a subsequent release ?
