vantjs

vantjs is a platform-independent javascript and typescript interface to the Davis Vantage Pro, Pro 2 and Vue. It works on any linux, windows or osx device!

Features

• Getting hourly, daily, monthly and yearly highs and lows (read more here)

const highsAndLows = await device.getHighsAndLows();

console.log(
    `Todays minimum temperature was ${highsAndLows.tempOut.day.low} °F!`
);
// Output: Today's minimum temperature was 25.3 °F!

console.log(
    `The maximum rain rate in the current hour was ${highsAndLows.rainRate.hour} in/h!`
);
// Output: The maximum rain rate in the current hour was 0.2 in/h!
Copy

• Getting realtime weather data (read more here)

const realtime = await device.getRichRealtimeData();

console.log(`Currently it's ${realtime.tempOut} °F!`);
// Output: Currently it's 45.2 °F!

console.log(
    `The wind blows from ${realtime.windDir} with an average speed of ${realtime.windAvg10m} mph!`
);
// Output: The wind blows from SW with an average speed of 23.12 mph!

• Converting the weather data automatically to the desired units

const device = await VantPro2Interface.create({
    units: {
        temperature: "°C",
        wind: "km/h",
        rain: "mm",
        ...
    },
    ....
});

const realtime = await device.getRichRealtimeData();
console.log(`It's ${realtime.tempIn} °C`);
// Output: It's 23.1233 °C

Beyond vantjs

vantjs is only a small part of the Vantage Environment.

While vantjs provides the direct serial connection to the weather station, the vant-api provides a convenient interface for this data in the form of a RESTful API for any kind of application. In the background it utilizes vant-db that manages a database that allows long-term storage and archiving of weather data. The vant-api package also includes a recorder that utilizes vantjs to repeatedly send weather data to the running REST API. These programs together form a robust platform that allows you to use your weather data pretty much anywhere.

⚠️ The Vantage Environment is still in active development. Once it is finished multiple guides will guide you through the process of setting up your very own vantage environment.
