Dew Point not showing

[Timo]

Hi,

Dew Point is not showing even though temperature and humidity is
registering:

http://riihineva.no-ip.org/weewx

Lämpötila ulkona = Outside Temperature
Kosteus ulkona = Outside Humidity

The week report shows that it is occasionally working. When it doesn't
work, humidity seems to be stuck in some way but still registering. At
~21:00 there is a real interruption.

Is there more dependencies than temperature and humidity only?

I had an Oregon Scientific station years ago.  As I recall it wouldn't calculate Dew Point below a certain temperature (presumedly because it doesn't calculate Frost Point, or something like that).  Your graphs tend to bear that out as it seems to only show DP above -15C.

I think you can have WeeWX calculate it by changing weewx.conf file under [StdWXCalculate] to "dewpoint = software".

Thanks a lot! I really didn't realize that it might come directly from
the weather station and not calculated by Weewx. Maybe the humidity
readings are also stuck for the same reason.
