$day($data_binding=...).wind.avg not working

[Graham Eddy]

under 4.7.0 $day.wind.avg works fine but $day($data_binding=...).wind.avg does not. is this expected?

(i have not tried the latter on earlier versions.)

I just tried it on my Mac and it worked fine. I even added it to the test suite (commit e907b59).

Are you sure that the binding "gw1000_binding" has wind? That is, it needs a daily summary schema that includes wind.

the weewx instance that owns gw1000 database reports $day.wind.avg fine:

the weewx instance that imports gw1000 database via gw1000_binding reports the ‘unrecognised’ error on $day($data_binding=‘gw1000_binding’).wind.avg. however, it is fine with $day($data_binding=‘gw1000_binding’).windSpeed etc:

this is the html template code that (successfully) imports scalar wind data and (unsuccessfully) vector wind data:

hopefully i’m just doing something stupid (i can fix that!)

this is on RPi 64bit bullseye (i gave up on macOS operational environment long ago as too mutant and mutating further…)

i hasten to clarify that those plot images are generated by the weewx instance that owns the gw1000 database. the other weewx instance generates html that only points to the existing image, but it does (try to) generate the text values via the tags

If I understand correctly, the instance that archives into the gw1000 can evaluate $day.wind.avg just fine, but the instance that imports it cannot.

I wonder if this is due to a time synchronization issue between the two instances?

The type 'wind' exists only in the daily summaries. In the main archive, it's been flattened into windSpeed and windDir. The daily summaries can only be used for aggregations over a midnight-to-midnight day, or the very last day in the database, that is, midnight to the last update of the daily summaries.

This test could fail if the archive records don't match between the two instances. For example, perhaps the data in the gw1000 database isn't quite ready when the other instance needs it?

See the Customizing Guide for an example where this happened.

this probably points to it. i created a database several days ago (took 7 hours to do calc-missing !!!) that has not been updated since and i am generating reports using the date of the last record in that database - debugging skin mods. the daily records in that database will be correctly ‘daily’ with respect to the reporting date, but maybe something is trying to compare to current real date?
