Issues after weather station downtime

[david_h]

Hi  - I had a problem with my Davis Vantage Pro2 where it was not transmitting data for about 2 weeks.  After some maintenance it has started working again today, but when I get weewx going again, although the current weather readings are fine on my weather station website, the reports and graphs etc are all as at the date of the weather station failure.  I am getting the following errors from weewx in my Rpi syslog file:

I am using the belchertown skin.

Any ideas as to how I correct this please?

Many thanks

David.

Most likely this is a problem in the Belchertown skin: it forgot that values can sometimes be Python None. You'll have to ask the skin author.

There may be other problems (such as a corrupt logger), but the log excerpt is too short to tell.

Hi  - can anyone with familiarity with the excellent belchertown skin help with this error please?  The symptom is that the daily summaries, NOAA reports, forecasts etc are all stuck on 27 December - which is when the weather station stopped transmitting data.  The weather station is working again now, after replacing the ISS board etc, but daily summaries are all wrong.   I am using an old version of the belchertown skin that hasn't been updated for a while, but it was all working fine prior to the malfunction with my weather station transmitter. 

Any help that anyone can give would be much appreciated.

Thanks

David.
