Help testing an extension.

[John Kline]

Hi all,

I have an extension, LoopData, that can be used to update weewx report web pages on each loop packet (of course, JavaScript is needed in the web pages).

I’ve tested it with US, METRIC and METRICWX databases targeting US and metric reports.

Alas, I have only tested it with the the RainWise CC3000 and IP100 drivers and the simulator.  I suspect there will be issues when other drivers are tried.

It’s been tried by a couple of people on weewx-users, but at this point, I’d prefer weewx-developers give it a try.

I would appreciate it if some of you could try it.  Running it just for a couple of loop cycles is fine—to see if the loop-data.txt file is being produced and to verify the contents of it look good.

The install sets loop_data_dir to/home/weewx/public_html (yes, it should use a symbolic here).  Change it as necessary.

The file is named loop-data.txt (by default).

Please note, one user complained, after installing many versions, that one version of loopdata broke his installation.  He’s since fixed his weewx.conf.  I don’t believe the very simple install did that; but I feel it necessary to make you aware this.  If you do find this issue. Simply copy over the backup of weewx.conf that the install makes and restart.  (And of course, report the issue.)

The aim is for loop-data.txt to yield exactly what the JavaScript needs right out of the box.  Please let me know what issues you run into.

Install at head from https://github.com/chaunceygardiner/weewx-loopdata. Detailed installation instructions are there.

Details of LoopData

(BTW, credit to Gary for his great rtgd work that inspired this.)

To use LoopData, you pick a report to target (e.g., SeasonsReport) and then all scalar observations, along with day high (w/ time), low (w/time), average, weighted average and sums are available in a form appropriate for the report.  That is, all of these are automatically converted and formatted to match the target report.  As such, if the SeasonsReport is targeted, and one changes windSpeed in the SeasonsReport to be in meters per second with three decimal places, windSpeed in the loop-data.txt file will also be in meters per second with three decimal places.  Formatting with a label is achieved simply by prepending FMT_ to the observation.  As such, FMT_SUM_rain would yield “FMT_SUM_rain”: “0.03 in” in loop-data.txt if .03 inches of rain fell today (even if the database was METRIC).

Of course, if all of this data would make for an enormous loop-data.txt file: <obs>, FMT_<obs>, SUM_<obs>, FMT_SUM_<obs>, AVG_<obs>, FMT_AVG_<obs> and so on and so forth).  As such, it is possible to only include what you are going to use.

For example:

   [[Include]]

        fields = dateTime, windSpeed, COMPASS_windDir, DESC_barometerRate, FMT_barometer, FMT_SUM_rain, FMT_dewpoint, FMT_heatindex, FMT_outHumidity, FMT_outTemp, FMT_rainRate, FMT_windchill, FMT_windSpeed, FMT_HI_windGust, FMT_10mMaxGust, pm2_5_aqi, pm2_5_aqic

Yields a loop-data.txt file containing the following.  This is assuming everything in the include is in the loop packet.  Anything not in the loop packet will, of course, not be present in loop-data.txt.

{"dateTime": 1593911456, "windSpeed": "4.4", "COMPASS_windDir": "N", "DESC_barometerRate": "Falling Slowly", "FMT_barometer": "29.965 inHg", "FMT_SUM_rain": "0.00 in", "FMT_dewpoint": "55.4\u00b0F", "FMT_heatindex": "88.2\u00b0F", "FMT_outHumidity": "33%", "FMT_outTemp": "88.2\u00b0F", "FMT_rainRate": "0.00 in/h", "FMT_windchill": "88.2\u00b0F", "FMT_windSpeed": "4.4 mph", "FMT_HI_windGust": "12.6 mph", "FMT_10mMaxGust": "9.1 mph", "pm2_5_aqi": "46", "pm2_5_aqic": "11204096"}

Please let me know if you were successful and/or any issues that arose.

Cheers,

John

Incidentally, I strongly encourage coding to the same support matrix as WeeWX itself: Python v2.7 and V3.5 and later. Otherwise, you'll exclude a lot of potential users.

Thanks Tom.  I appreciate you trying this out.

Another tester reported this and I’ve subsequently updated the extension to check for Python 3.7.  And updated the README accordingly.

I’d rather not give up the type annotations and I do understand this limits potential users.  I’m also not listing any of my stuff in any WeeWX 4 compatible lists (or any lists for that matter) as I think it would be misleading considering the limitation.

Cheers,

John

Hi John,

I'm just about to test your extension. The installation is on a raspi that gets its data only via SDR. There is no station connected. Barometer data is not available on this test system.

shortly after the start of weewx there is this error:

Hi Michael,

Thank you for testing my extension.  I added a check for barometer value of None in the database.  Would you give 1.3.18 a try?

Cheers,

John

Hi John,

great, thankyou. Now weewx-loopdata works as expected

But now I have another question: I installed the Skin Weatherboard. What do I have to do, so that the page refreshes automatically when the values are updated. Until now I have to update the page manually with F5. Then in 5 minutes rhythm updated values are displayed.

Kind Regards

Michael

Asssuming loop-data.txt is being generated on every loop, some questions:

Is WeatherBoard pointed to the correct location where loop-data.txt is located?

Did you add the fields required by WeatherBoard (see WeatherBoard README) to the fields entry in the LoopData section of weewx.conf?

Perhaps you are missing a field that WeatherBoard requires?  Do you see any JavaScript errors on the WeatherBoard page (Developer Tools->View JavaScript console or something of that sort).  If so, would you tell me what those errors are?

Hi Michael,

I rewrote LoopData to use the same names as Cheetah (rather than keeping my home-grown naming scheme).

If you are planning on going further with LoopData (and WeatherBoard) I recommend that you switch to:

https://github.com/chaunceygardiner/weewx-loopdata/tree/development

and

https://github.com/chaunceygardiner/weewx-weatherboard/tree/development

You’ll find the names you can include much more familiar.  Here’ my loop-data.txt now:

current and day are pretty much all there.  You can’t use .format(xxx); but you can use .formatted (which is the same as .format(add_label=False).
unit.label.<obs> works.
Trend only has barometer and it’s for a hard coded (at present) 3-hour barometer trend:
trend.barometer
Also, trend.barometer.desc is a made up, not currently localized, way of getting steady, falling slowly, etc.  I’ve got to figure something out for that.
Lastly, there’s also a 15m period just for windGust.
15m.windGust.max
15m.windGust.maxtime

Cheers,
John

Asssuming loop-data.txt is being generated on every loop, some questions:

Is WeatherBoard pointed to the correct location where loop-data.txt is located?

Did you add the fields required by WeatherBoard (see WeatherBoard README) to the fields entry in the LoopData section of weewx.conf?

Perhaps you are missing a field that WeatherBoard requires?  Do you see any JavaScript errors on the WeatherBoard page (Developer Tools->View JavaScript console or something of that sort).  If so, would you tell me what those errors are?

Hi John,

great, thankyou. Now weewx-loopdata works as expected

But now I have another question: I installed the Skin Weatherboard. What do I have to do, so that the page refreshes automatically when the values are updated. Until now I have to update the page manually with F5. Then in 5 minutes rhythm updated values are displayed.

Kind Regards

Hi John,

I have just tested the version LOOP_DATA_VERSION = '2.0.b2'.
the following error appears after a few minutes runtime:

Hi Michael,

I rewrote LoopData to use the same names as Cheetah (rather than keeping my home-grown naming scheme).

If you are planning on going further with LoopData (and WeatherBoard) I recommend that you switch to:

https://github.com/chaunceygardiner/weewx-loopdata/tree/development

and

https://github.com/chaunceygardiner/weewx-weatherboard/tree/development

You’ll find the names you can include much more familiar.  Here’ my loop-data.txt now:

{"current.dateTime.raw": 1594525666, "current.windSpeed.raw": 0.0, "current.windSpeed": "0.0 mph", "current.windDir.ordinal_compass": "N/A", "trend.barometer.desc": "Rising Slowly", "current.barometer": "29.976 inHg", "day.rain.sum": "0.00 in", "current.dewpoint": "55.5\u00b0F", "current.heatindex": "68.2\u00b0F", "current.outHumidity": "64%", "current.outTemp": "68.2\u00b0F", "current.rainRate": "0.00 in/h", "current.windchill": "68.2\u00b0F", "day.windGust.maxtime": "07/11/2020 03:58:52 PM", "day.windGust.max": "13.8 mph", "10m.windGust.max": "4.4 mph", "current.pm2_5_aqi.raw": 29.0, "current.pm2_5_aqic.raw": 2746368, "day.wind.maxtime": "07/11/2020 03:58:52 PM", "day.wind.max.formatted": "13.8", "day.wind.gustdir.formatted": "45", "day.outTemp.maxtime": "07/11/2020 02:01:02 PM", "day.outTemp.max.formatted": "87.2", "day.outTemp.mintime": "07/11/2020 06:15:54 AM", "day.outTemp.min.formatted": "53.2", "day.heatindex.maxtime": "07/11/2020 02:01:02 PM", "day.heatindex.max.formatted": "87.2", "day.windchill.mintime": "07/11/2020 06:15:54 AM", "day.windchill.min.formatted": "53.2", "day.dewpoint.maxtime": "07/11/2020 07:59:56 AM", "day.dewpoint.max.formatted": "61.4", "day.dewpoint.mintime": "07/11/2020 06:15:54 AM", "day.dewpoint.min.formatted": "51.8", "day.outHumidity.maxtime": "07/11/2020 07:06:56 AM", "day.outHumidity.max.formatted": "96", "day.outHumidity.mintime": "07/11/2020 02:03:02 PM", "day.outHumidity.min.formatted": "34", "day.barometer.maxtime": "07/11/2020 10:36:58 AM", "day.barometer.max.formatted": "30.025", "day.barometer.minttime": "day.barometer.minttime", "day.barometer.min.formatted": "29.945", "day.rain.sum.formatted": "0.00", "day.rainRate.maxtime": "07/11/2020 12:00:02 AM", "day.rainRate.max.formatted": "0.00", "day.wind.avg.formatted": "2.0", "day.wind.rms.formatted": "2.6", "day.wind.vecavg.formatted": "1.8", "day.wind.vecdir.formatted": "357", "current.consBatteryVoltage": "5.3 V", "current.supplyVoltage": "6.6 V"}
current and day are pretty much all there.  You can’t use .format(xxx); but you can use .formatted (which is the same as .format(add_label=False).
unit.label.<obs> works.
Trend only has barometer and it’s for a hard coded (at present) 3-hour barometer trend:
trend.barometer
Also, trend.barometer.desc is a made up, not currently localized, way of getting steady, falling slowly, etc.  I’ve got to figure something out for that.
Lastly, there’s also a 15m period just for windGust.
15m.windGust.max
15m.windGust.maxtime

Cheers,
John

Hi Michael,

Would you give 2.0.b3 a try and let me know how it goes?

If it doesn’t work, I’ll run with the simulator (and no barometer/pressure) before I push another version.

Cheers,

John

Hi Michael,

I just pushed new versions of LoopData and WeatherBoard on the development branches.

I’ve now tested LoopData with a simulator without barometer and pressure readings.

I’ve also updated the WeatherBoard JavaScript to be resistant to missing observations.

If you try these, please let me know how it goes.

Cheers,

John

Hi, John,

I made the updates. There are no more error messages now and the file loop-data.txt is permanently re-created.
But there was a problem with the paths.

When I use some of the defaults:

[LoopData]
    [[FileSpec]]
        loop_data_dir = /home/weewx/loop-data
       
and:

  [[WeatherBoardReport]]
        # HTML_ROOT = public_html/weatherboard
        HTML_ROOT = /var/www/html/weatherboard
        skin = WeatherBoard
        [[[Extras]]]
            title = my-weather-website.com WeatherBoard&trade;
            subtitle = Updated continuously
            logo = ""
            loop_data_file = ../loop-data.txt

with this configuration loop-data.txt not found.

Change to:

    [[FileSpec]]
        loop_data_dir = /var/www/html
        filename = loop-data.txt

all is fine.

the page updates itself automatically every few seconds.
Thanks for your help and patience

Kind Regards

Michael

Hi Michael,

Thank you for trying it out!  I thank you for your help and patience.

I’ll need to fix the default paths.
