windDir is None since upgrading to 4.6.2 from 4.5.1 on VP2

[James Taylor]

Hello

I've upgraded to weewx 4.6.2 and found out that my vantage Pro2 REC is giving a different output for windDir

record_generation is set to hardware in weewx.conf

I amended StdPrint to output new_archive_record to stdout and log.debug and I can see a difference

4.6.2 -

I've issued a clear-memory just in case it was corrupted, but I'm now thinking something else is going on.  The Loop data is fine and mqtt is working as expected.

Any idea on how to debug this some more?

Thanks

I do not have any output of windir and wingustdir after first update to 4.6.2.

Even if I reverted a full machine backup, the output of weewxd still shows no data for the wind...

Even after flashing the py file from https://groups.google.com/g/weewx-user/c/9N8gg44u8Q0, I cannot see any data.

I cleared the station's memory...

No idea.

Your windSpeed and windGust are 0.0 so there is no direction.

[James Taylor]

Yes, unfortunately that isn't the case with my output :-(

[gjr80]

The 4.5.1 archive record looks very much like a software generated archive record, you can tell by the windDir value. The windDir value in a hardware generated archive record from a VP2 appears in multiples of 12.5 degrees - that is fixed and a limitation of the archive record format emitted from the console/logger. In a WeeWX VP2 hardware generated archive record the wind direction values will be multiples of 12.5 or None. Software generated archive records contain an average of the loop packet windDir values. windDir in a VP2 loop packet is in whole degrees and not subject to the '12.5 degree multiple' effect. So in a software generated archive record windDir will be a float, usually with a number of decimal places and certainly (almost always) not a multiple of 12.5. I also see THSW in the archive records, THSW is only present in the LOOP2 archive packet so I am guessing you are using LOOP2 instead of the normal LOOP1 packet. Should not be a problem but it's something out of the ordinary.

Might help to see the WeeWX startup for each case and weewx.conf to understand your configuration. You say record generation is set to hardware in weewx.conf, that is great but not necessarily what is used by WeeWX. WeeWX will try hardware and if for some reason it doesn't work/isn't available WeeWX will drop back to software record generation. Always best to check what is in the log.

I would also look at the loop packets, what wind direction values do you see in loop packets? What appears in the subsequent archive record? No need to modify WeeWX, just run WeeWX directly and you will see loop packets and archive records direct to console.

Thanks Gary

Yes - I forgot about the 12.5 multiples thing so yes gives me a possible idea on what is going to work out what has changed in behavior as the weewx.conf hasn't changed (apart from the version details)

[James Taylor]

Tonight's debug....

So I've detected that I'm not getting windDir on the archive record from the Vantage Pro 2 on the records coming every 5 mins, compared to any archive records received after a restart, so possibly a hardware issue.

I've also worked out that, I appear to be getting caught up with getting a weewx.CannotCalculate (hence a None) from calc_windDir in wxxtypes.py, because the default calculation is software for windDir under wxservices.py

If I set it to windDir = hardware, then it uses the loop entries and creates the averages!

Hello

So this was broken by commit ec958a0 (https://github.com/weewx/weewx/commit/ec958a0658612ef3bce90ab5c6e825ef0d329e8e).

To give the history, to allow Belchertown to output / graph rxCheckPercent as discussed here https://www.mail-archive.com/weewx...@googlegroups.com/msg21816.html, it meant we delete windDir from the Vantage archive record which means we then process the loop packets as an accumulator

I'm guessing this will need the brains / knowledge of Tom to comment???

So if I understand your post correctly you are running Pat's service to delete windDir from archive records? If so that sort of info would have been nice to know from the outset; that is why we ask for a startup log with debug=1 - it gives us key WeeWX config info so we know what services are being run and what aren't.

Again if you are running Pat's service then the solution should be fairly straightforward; instead of running the service as a data service, run it as a process service but list it after StdWxCalculate. This way StdWxCalculate can do whatever to the archive record and then Pat's service will come along and delete windDir. When StdArchive steps in it will extract windDir from the accumulator as before (assuming windDir is in loop packets) and add it to the archive record before it is saved to database. Making Pat's service an archive service would probably work as well, as long as it was listed in archive_services in weewx.conf before StdArchive.

Sorry Gary

Yes I was also annoyed when I caught the extension and remembered why it was there :-(   I did learn a lot more about the code setup.  I had been running the debug at 2 and still missed it so therefore renamed it to windDir so it matches the same case at least!

I'm still trying to fully understand the 'services' implementation, but yes I've moved it from data_services to the end of process_services, and also before weewx.engine.StdArchive and in both cases it continued to operate as expected.

I will update Belchertown users in case they are using Pat's service.

Thanks again and sorry for the long winded way of getting there.

No problems James.

Regards the services, think of the [[Services]] stanza as a matrix. When an event occurs (for example the arrival of a new archive record) WeeWX works it way down each 'row' (ie each xxxx_services option) in turn checking each 'column' (ie each service defined in that row) to see if that service was bound to the event in question. If it is bound WeeWX executes the designated code (method) for that service, if it's not bound WeeWX moves on to the next 'column'/service. The services are loosely grouped by type, but there is really no great difference between service types. Order matters, typically services towards the top of the list (eg data) will be doing things to the incoming data to maybe add observations, eg you may have a service that reads air quality data from a separate sensor suite and adds it to loop packets and archive records (such a service would likely be bound to the new archive record and new loop packet events). You would not put such a service after StdArchive as the data would not be saved to the archive. Services that process the incoming data and perhaps change the archive record (eg StdWxCalculate) need to be 'placed' after all of the incoming data has been assembled but before StdArchive writes the archive record to database.

In your case some careful placement of your service in the processing chain has solved the problem.

Thanks for the info.
