Private Weather App, powered by Dark Sky, with Google Apps Script backend

I was unhappy with stock weather app, because it refreshes infrequently (three hours old "current" temperature? Seriously?). So I quickly put together my own. 


It's a "push" Indicator App, and the push data is provided by Google Apps Script set to run every 15 min. Those scripts are hosted by Google (for free). The script retrieves data from The Dark Sky Forecast API (https://developer.forecast.io/). It's free up to 1000 request per day, but you have to register and get API key you need to put into the script:


  

function getDarkSkyWeather() {
  var result = UrlFetchApp.fetch("https://api.forecast.io/forecast/<PUT YOUR FORECAST API KEY HERE>/35.00,-120.00?units=si&exclude=flags,hourly,daily,alerts");
  //Logger.log(result);
  var json = JSON.parse(result);
  //Logger.log(json.currently);
  return json;
}

function convertDarkSkyToLaMetric(darkSkyJson) {
  var temp = darkSkyJson.currently.temperature;
  var icon = darkSkyJson.currently.icon;
  var minutelySummary = darkSkyJson.minutely.summary;
  var minutelyIcon = darkSkyJson.minutely.icon;
  
  return {
    "frames": [
        {
            "index": 0,
            "text": Math.round(temp) + "°",
            "icon": pickIcon(icon)
        },
        {
            "index": 1,
            "text": minutelySummary,
            "icon": pickIcon(minutelyIcon)
        },
    ]
  }
}

function pickIcon(icon) {   // clear-day, clear-night, rain, snow, sleet, wind, fog, cloudy, partly-cloudy-day, or partly-cloudy-night
  switch (icon) {
      case "clear-day": return "a2282";
      case "cloudy": return "a2283";
      case "rain": return "a2284";
      case "sleet": return "a160";
      case "partly-cloudy-day": return "a2286";
      case "snow": return "a2289";
      case "clear-night": return "i2314";
      case "wind": return "a2440";
      case "fog": return "i2158";
      case "partly-cloudy-night": return "i2152";
      default: return "i73";
  }
}
      
function executePost() {
  var payload = convertDarkSkyToLaMetric(getDarkSkyWeather());
  var options = {
        "method" : "post",
        "payload" : JSON.stringify(payload),
        "contentType": "application/json",
        "headers" : {
            "X-Access-Token" : "<PUT YOUR LAMETRIC ACCESS TOKEN HERE>"
        }
  };
  var result = UrlFetchApp.fetch("https://developer.lametric.com/api/V1/dev/widget/update/com.lametric.<PUT YOUR APP ID HERE>/1", options);
  Logger.log(result);
}

1. Here you can find information on updating apps. We've added instructions.


2. Currently it is not possible to use icons from LaMetric Weather App, but you can create your own.

Please follow instructions in User Guide (7.6. Searching and creating icons).


And some great news: in the next LaMetric firmware the weather data on LaMetric Weather App will be refreshed once in 1 and half hour.

Here is response I've got for your coordinates:

Ok.

Looks like i have to better lat long or something. Thanks.

I have to learn how  to see the result i gs also.... 

Getting there...

Kind regards

Stefan

You can use those Logger.log functions to see results. You can uncomment them, run your code and then click  "View / Log" menu

Great!

It was the exclude that i have not seen....

Hourly works now, daily give wrong day. 

Kind regards

Stefan

Hi. Would anybody be kind enough to provide step by step instructions on how to make this work? 

Thanks
I am in Kolkata. So I need details weather report for Kolkata and surrounding.
