Topic: Help downloading data from Weather Underground

[IgnesFatui]

First of all, huge thanks to all of the contributors to this project for their excellent work. I now have WeeWx running alongside Pi Hole on a Raspberry Pi and I'm very delighted with the functionality.

I have been uploading weather data to Weather Underground since mid-2015 from my Ambient Weather device. Now I would like to get that data back so that I can add it to the WeeWX database. Fortunately I am grandfathered in for 1500 per day/30 per minute API calls.

I came across the WU-History app (https://github.com/ktrue/WU-History) which works fine, but I can't find a way to tell it to download the daily (5 minute interval) observations for the past 6 years. However, I am able to download the data a day at a time.

It looks like I should be passing values to the script:

Code: [Select]

$da = $_REQUEST['day'];
$mo = $_REQUEST['month'];
$yr = $_REQUEST['year'];
$da2 = $_REQUEST['dayend'];
$mo2 = $_REQUEST['monthend'];
$yr2 = $_REQUEST['yearend'];
$units = $_REQUEST['units'];
$mode = $_REQUEST['mode'];
I tried https://mywebsite.com/WXDailyHistory.php?year=2021&month=1&day=1&dayend=31&mode=1&debug=y To get the data for January of this year, but it only returned data for January 1.

The other concern is that I think the current Weather Underground API is https://api.weather.com/v2/pws/history/all??stationId=KSSCCCCCN&format=json&units=m&date=YYYYMMDD&apiKey=xxxxxxxxxxx, but the script uses https://www.wunderground.com/weatherstation/WXDailyHistory.asp

I wonder if I should just run a JavaScript script from my browser to get this data? Any guidance would be greatly appreciated.

For getting the data, the only script you need to run from https://github.com/ktrue/WU-history is the WXDailyHistory.PHP script.  It will access the api.weather.gov JSON data, save it to a cache file, and create a .csv of the data just like the old WXDailyHistory.asp page used to on the WU site.

For a day's data, you should use (localhost)/WXDailyHistory.php?month=1&day=1&year=2021&format=1&graphspan=day
The day data request will only return one full day's data .. increment the &day= value for other dates within the month.

OK, I think I understand now. Thank you for the explanation. I'm sure I can kludge something together to programmatically retrieve all 1800+ records.
