Aeris forecast not displaying.

[David Barto]

galfert posted that you can get free Aeris forecasting:

The free Aeris Weather account is not advertised. You have to use the link I provided to get in on the special "Contributor account" only for those that contribute with their station to PWSweather.com.

This link: https://www.aerisweather.com/signup/pws/

-----

So I signed up for Aeris through the pws, and got my 2 hashes.

I added the Aeris data to weewx.conf and restarted.
The forecast page doesn't show any forecast for Aeris, while the
NWS does show up.

The log output for weewx is showing an error:

Clearly I've not configured something correctly. Anyone want to point out the error of my ways?

Thanks.

I switched from my free trial Aeris to a free one based on the thread you mention.  I got back the same client ID and secret.  It continues to work for me.

You should be able to do something like the following to test:

PYTHONPATH=/home/weewx/bin python3 bin/user/forecast.py --method Aeris --action download --client-id XXX --client-secret XXX--loc "37.431495,-122.110937"

If you could do that, you could quickly see wether the issue is that no forecast is available for the location you requested.

Alas, I notice that Aeris isn’t supported when running as main.  I added the support to do that and fixed some bugs WRT command line arguments.  I will add it to my fork, but I will need to test more.

What version of WeeWX and the forecast plugin are you running?

ALSO, PLEASE REPLY ON THE LIST RATHER THAN DIRECTLY TO ME.

Here’s a diff showing the changes I had to make so that the command below will run.

Please make those changes and then run the command again pointing to your changed file.  You don’t even have to update the forecast.py that weewx is using.  This is just so that you don’t get the method not supported error below when running directly.

Of course, you also need to plug in your client-I’d and secret-key.

BTW, you didn’t have to send me this error.  I told you it wouldn’t work without modifying the code.

Yikes.  Forgot the diff.  The line numbers won’t match, but this should be easy to apply to your current forecast.py.

Brilliant. Now I get the forecast if I set the location to “Poway, CA.” and that works for me.

Where in the configuration for Aeris would I change the location for getting their forecast for my city?

Add location to the Aeris entry in weewx.conf.

    [[Aeris]]

        client_id = XXX

        client_secret = XXX

        location = "Poway, CA"

Well dang, set it as noted, getting the same failure.

I’ll just wait until 4.0 and see if that changes anything.

If you got that failure with weewx using the same forecast.py you used successfully from the command line, that is indeed strange.  Are you really sure you used the same client-id and secret-key in weewx.conf that you used from the command line?

The other option is that the service was temporarily down.  That’s what a 503 is.  It could actually start working for you.

And of assumes that you are trying this from the same machine where you ran the forecast from the command line.  Also assuming you don’t have intermittent network connectivity problems.

Hi David,

I tried this in my weewx.conf file.  You’ll need to remove the space in the location (after the comma) to get this to run.

location = "Poway,CA"

I’ll add code to encode the space on my fork (if that solves the issue), but you should be in business 3.9.2 by simply removing the space.

I only have python installed on my weather machine/http host, and I copied the id/secret data from the weewx.conf file to the command line. So all that stayed the same.

This morning it is still reporting the same error(s).
