Send arbitrary commands to a Particle Photon (new version of Spark Core) via express
var express = require('express');
var app = express(),
var spark = require('spark');
var _ = require('lodash');
require('dotenv').load(); // reads particle username and password from a file named .env that you can .gitignore
var deviceName = "InternetButton"; // set this to the name of your device
// Login and retrive the device
var getDevice = spark.login({
username: process.env.PARTICLE_USERNAME,
password: process.env.PARTICLE_PASSWORD
}).then(function() {
return spark.listDevices();
}).then(function(devices) {
var device = _.findWhere(devices, {name: deviceName});
if (device) {
return device;
} else {
throw new Error('Device ' + deviceName + ' not found. Avaliable devices: ' + _.pluck(devices, 'name').join(', '));
}
});
// app.all supports GET, POST, etc.
app.all('/device/:command/:value?', function(req, res) {
