Hello,

Can anyone offer help on why I can't download forecast from Wunderground, despite having updated my API key?

I see this in the logs:

The forecast extension has not been updated to use WU’s new API.

If you navigate your browser to the URL you have in your log snippet:

http://api.wunderground.com/api

You will get:

Service Unavailable

I think I understand what you meant. Not that my API key needed to be updated, but that http://api.wunderground.com/api/ is no longer the URL.

I see from the documentation that the URL is now api.weather.com. Should the updated forecast extension not have taken care of that?

my understanding is that forecast has not been updated to python3/weewx4 as yet (all good things take time)

and i was pointed to a fork that has been: https://github.com/chaunceygardiner/weewx-forecast

i have been playing with it for a week or so and the forecast data (i am using WMO) was okay in mild weather but way off in the current freezing episode - presumably that would be the data source, not the weewx extension. i will probably give another source a go but my expectations are not high for off-shore predictions of aussie bush weather

That was a higher version than I was previously using. Just installed it, and I get...

Aug 4 09:46:15 weather journal: weewx[8782] INFO user.forecast: WUThread: WU: download forecast from 'http://api.wunderground.com/api/XXXXXXXXXXXXXXXXXXXXXXXXXXXX0a13/hourly10day/q/XXXXXX.json'

I've been in touch with WU Support, and that is definitely not the URL. So the next question is: in which file do I alter this, so that it uses the correct URL, and is the syntax the same?

i have been avoiding WU like the plague (probably a bad analogy at the moment..) because of its stability issues with no resolution in sight, so i have no idea about WU interface

The chaunceygardiner fork is mine. I originally modified the extension to get it working for me as I was running the WeeWX 4.x beta. Others asked for it, so I made it available. I tested everything *except* WU and got it working. This fork is intended as an interim solution while waiting for Matthew to update the extension.

I did look at updating WU. It’s not just a URL change. The API changed and the change is substantial. One user has mentioned that UKMO is is moving to this API; so perhaps I should take another look at this. I’ll have some time this weekend to assess the situation.

I started to look into OWM, but too much faffing around, with downloading Postman etc. I tried with curl, but ...

[root@weather weewx]# curl http://api.openweathermap.org/data/3.0/stations?appid=XXXXXXXXX

[][root@weather weewx]#

Ah, well. I will stick with the basic Weewx.

Thank you all.

i vaguely recall one trivial step to get an API key from OWM, that was all.

and install the forecast extension of course, telling it to use OWM rather than WU or NWS and giving it API key

i think you have the wrong end of the stick there: i thought you wanted to download forecasts, not upload your station data.

on my test server:

Yep, he did change the subject on us.

I just double checked. I still have OWM running and my fork is *fetching* forecasts just fine.

We seem to have crossed lines, and I apologise. I didn't change my intentions, but no doubt expressed myself inaccurately.

Let me try to clear up any confusion. My weather station is pushing data perfectly, to the Wunderground servers. That's not a problem.

What I want is to have forecasts at the bottom of my weather screen. I'm attaching a screenshot of the bottom half of my Weewx front end. That is the 'WU' strip to the left, and as you can see, it has no data. I would like it to have data. It was working perfectly up until, well .. I don't know. No doubt until they changed something at the Weather Underground.

So what I have been trying to do in this thread is to pull data from WU (and latterly OWM) to have it displayed here at home.

After learning that OWM forecasts can be pulled with the same syntax in the weewx.conf as WU, I entered my API key into that config file, and restarted. This looks a bit more promising...

Aug 5 10:10:14 weather journal: weewx[2680] INFO user.forecast: OWMThread: OWM: download forecast from 'http://api.openweathermap.org/data/2.5/forecast?APPID=XXXXXXXXXXXXXXXXXXXXXXXXXXXX112c&lat=XXXXX&lon=XXXXXX'

Aug 5 10:10:15 weather journal: weewx[2680] INFO weewx.cheetahgenerator: Generated 14 files for report StandardReport in 0.25 seconds

Aug 5 10:10:15 weather journal: weewx[2680] INFO user.forecast: OWMThread: OWM: got 40 forecast records

Aug 5 10:10:15 weather journal: weewx[2680] INFO weewx.manager: Added record 2020-08-05 10:10:15 BST (1596618615) to database 'forecast.sdb'

Aug 5 10:10:15 weather journal: weewx[2680] INFO weewx.imagegenerator: Generated 12 images for report StandardReport in 0.15 seconds

All right.

So what I need now, is to get that forecast data displayed. I set all of this up with WU back in January of 2020 when I first got my Oregon Scientific station, and aside from WU changing their API, everything was perfect. But as I probably mentioned, we moved house back in November, and it is only this past weekend that I got the station out of the garage and set it up. So I am very rusty as to how to get the forecasts to appear.

Any help you could give, would be much appreciated.

the forecast skin’s .inc files have a flag you set to indicate which forecast db data to display: ‘WU’, ‘OWN’, etc.

this is in addition to setting similar value in .conf to indicate what to put into forecast db.

i haven’t looked any further into this extension, pending the ‘official’ weewx4 one hopefully forthcoming

Yes, I thought I had defined that correctly ...

/home/weewx/skins/forecast

## #set global $forecast_strip_settings['source'] = 'OWM'

## <body onload="populate_strip('nws', 'NWS'); populate_strip('owm', 'OWM'">

#set $strip_source = 'OWM'

populate_strip('owm_strip', 'OWM');

Yes, 'david' is the skin I have defined in weewx.conf so I could be sure that I wouldn't overwrite stuff when upgrading.

Don’t change ‘wu_strip’ to ‘owm_strip’. It is a referring to an element on the page that has an id of wu_strip. Perhaps that’s not the greatest id, but it is what it is.

So, that should read:

populate_strip(‘wu_strip’, ‘OWM’);

In addition, you need to change $strip_source in forecast_strip.inc:

## Which forecasts should be displayed?

#set $strip_source = 'WU'

Change to:

#set $strip_source = 'OWM'
