    location: "Palm Springs, CA"
});

    console.log("+", "istate", thing.state("meta"), "\n ", thing.state("istate"));
});

Get the forecasts. Each specific forecast for a point in time, for example, 3p on January 3, will create a new "Thing".

Changes to the forecast will create istate events.

const iotdb = require('iotdb')
iotdb.use("homestar-openweathermap")

const things = iotdb.connect("OpenWeatherMapForecast", {
    location: "Palm Springs, CA"
});
things.on("istate", thing => {
