Wind Data Missing

[Andre]

Hardware: Davis Vantage Vue

Raspberry Pi 4: Install with DEB package

WeeWX: 4.1.1

Skin: Belchertown 1.2b6

Actually, I just wanted to quickly correct a too high value of the rain rate. So I did:

1. wee_database --drop-daily

2. wee_database --rebuild-daily

3. wee_database --update

After that the too high rain rate value was corrected, but the "snapshot" area in the Belchertown skin did not work anymore. 

So I uninstalled and reinstalled the Belchertown skin. After that everything worked as desired, but now the wind values were missing. Also the NOAA files were completely missing the wind data.

I deleted all NOAA files and hoped that the wind data would be generated. Unfortunately without success.

Can someone help me to solve the problem?

Best regards, Andre

You did not include a log, but on the basis of similar problems, I would bet that you used the wrong combination of schema and 'manager' in your configuration file, weewx.conf.

Please post the section [DataBindings] in weewx.conf

Thanks for reply, Tom.

Here is my 

[DataBindings]
   
    [[wx_binding]]
        # The database must match one of the sections in [Databases].
        # This is likely to be the only option you would want to change.
        database = archive_sqlite
        # The name of the table within the database
        table_name = archive
        # The manager handles aggregation of data for historical summaries
        manager = weewx.manager.DaySummaryManager
        # The schema defines the structure of the database.
        # It is *only* used when the database is created.
        #schema = schemas.wview_extended.schema
        schema = user.extensions.schema_extended

It looks like you are using a custom schema. May we see it? It should be in /usr/share/weewx/user/extensions.py

It's a subtle error, but you're mixing the old style way of specifying and managing a schema with the new way. Try changing the [DataBindings] section to look like this:

[DataBindings]
   
    [[wx_binding]]
        # The database must match one of the sections in [Databases].
        # This is likely to be the only option you would want to change.
        database = archive_sqlite
        # The name of the table within the database
        table_name = archive
        # The manager handles aggregation of data for historical summaries

        manager = weewx.manager.WXDaySummaryManager

        # The schema defines the structure of the database.
        # It is *only* used when the database is created.
        #schema = schemas.wview_extended.schema
        schema = user.extensions.schema_extended

Then try rebuilding the daily summaries.

Sorry. We really should have a better error message.

Thanks for your help, Tom.

I got following message:

My apologies. The option should be

        manager = weewx.wxmanager.WXDaySummaryManager

Thank you very much, dear Tom.

Now it works as expected.

I learned more about weewx again.
