GW Builder - Weather Data Submission Tool

This package is purposed to submit weather data to a weather server using the gWeather protocol. It supports data sorting on a minutely basis and a few basic field types the weather data can stored into.

Usage

Installation

You can install the package in the usual way by running

> yarn add lx-gwbuilder

or

> npm i lx-gwbuilder

Make sure that needle is installed as project dependency.

Integration

First, create a builder instance:

const GwBuilder = require('lx-gwbuilder');

const builder = new GwBuilder(
	"<client-id>",
	"<client-secret>",
	"<host>", // Optional, defaults to "localhost"
	"<path>"  // Optional, defaults to "/gweather"
);

The builder now can be filled with sensor data and measurements. The following describes a general workflow:

builder.CreateSensor(builder.SensorType.Out, "My Outdoor Sensor")
	.AddMeasurement(builder.FieldType.Temperature,		12.0)	// 12.0°C
	.AddMeasurement(builder.FieldType.Humidity,			22  )	// 22%
	.AddMeasurement(builder.FieldType.WindSpeed,		 6.3)	// 6.3 km/h
	// Above defaults to sensor creation minute. 
	// Other identical fields will overwrite the value

	// Below inserts into the full minute at a given UNIX timestamp.
	// Different minute signatures will NOT overwrite each other.
	.AddMeasurement(builder.FieldType.Temperature,		-2.5, 1641819658)

Notice: Values should be unit normalized with the gWeather Protocol. See field reference for unit details

If the data injection is complete, the results can be submitted to the server by simply calling

builder.Submit()

Alternatively, you can submit or work with the data yourself by getting the serialized struct with builder.Serialize()
