Davis Weatherlink Download Issue

[CaveJohnson10]

I get this error when trying to upload data to Windy.

Dec 11, 2024, 8:20:04 PM Error Exception: Request failed for https://stations.windy.com returned code 400. Truncated server response: {"observations":[],"stations":[]} (use muteHttpExceptions option to examine full response)
at updateWindy_(Code:865:30)

I double checked my inputs to make sure everything is entered correctly. All the other functions complete successfully.

Any idea what is causing the issue?

Hmmm. A couple of thoughts.

1. Make sure that you're properly specifying your windyAPIKey as the whole key, within quotes, and the windyStationId as "0" (or if you have multiple, the correct ID number).

https://stations.windy.com/stations

https://github.com/leoherzog/WundergroundStationForwarder/blob/v2.8.2/code.gs#L42-L44

2. If you're sure those are correct, let's add some additional logging to the updateWindy_() function.

↓

// https://community.windy.com/topic/8168/report-your-weather-station-data-to-windy
function updateWindy_() {
  
  let conditions = JSON.parse(CacheService.getScriptCache().get('conditions'));

  console.log(JSON.stringify(conditions)); // add this
  
  let request = 'https://stations.windy.com/pws/update/' + windyAPIKey;
  request += '?stationId=' + windyStationID;
  request += '&time=' + new Date(conditions.time).toISOString();
  if (conditions.temp != null) request += '&tempf=' + conditions.temp.f;
  if (conditions.dewpoint != null) request += '&dewptf=' + conditions.dewpoint.f;
  if (conditions.windSpeed != null) request += '&windspeedmph=' + conditions.windSpeed.mph;
  if (conditions.windGust != null) request += '&windgustmph=' + conditions.windGust.mph;
  if (conditions.winddir != null) request += '&winddir=' + conditions.winddir;
  if (conditions.pressure != null) request += '&baromin=' + conditions.pressure.inHg;
  if (conditions.humidity != null) request += '&humidity=' + conditions.humidity;
  if (conditions.precipLastHour != null) request += '&rainin=' + conditions.precipLastHour.in;
  if (conditions.uv != null) request += '&uv=' + conditions.uv;

  console.log(request); // and this
  
  let response = UrlFetchApp.fetch(request).getContentText();
  
  console.log(response);
  
  return response;
  
}

Unfortunately, this did not solve the issue and I am still receiving the exact same error.

[leoherzog]

Sorry, I should have been more clear. Now that those have been added, what do you see in the ☰▶ Execution tab logs every time updateWindy_() runs?

[leoherzog]

@CaveJohnson10 Still having the issue?

[CaveJohnson10]

Hi, Yes the exact same error occurs.

Jan 20, 2025, 6:02:13 PM Error Exception: Request failed for https://stations.windy.com returned code 400. Truncated server response: {"observations":[],"stations":[]} (use muteHttpExceptions option to examine full response)

[leoherzog]

Is Windy the only one that's failing? Do you have other upload destinations that are working?

[CaveJohnson10]

I just tried Weather Underground and the upload itself to WU is successful in the script BUT it doesn't send any actual data. On the station page on WU I can see that that it says Online (Updated 1 minute ago) and it updates every minute but there's no weather data showing. I am starting to think there is an issue with the information the script is fetching from Davis Weatherlink.

[leoherzog]

That's my suspicion as well.

Were you going to look further into the issue?
