simple climate monitor

climate.tessel.js

var Promise = require('es6-promise').Promise;
var tessel = require('tessel');
var wifi = require('wifi-cc3000');
var climatelib = require('climate-si7020');
var climate = climatelib.use(tessel.port['D']);
var http = require('http');
var led = tessel.led[0].output(0);
var led2 = tessel.led[1].output(0);

function checkClimate() {
    led2.output(1);
    climate.readHumidity(function(err, humid){
        climate.readTemperature(function(err, temp){
            send(temp.toFixed(2), humid.toFixed(2));
            setTimeout(checkClimate, 1000 * 600);
        });
    });
}

var climateReady = new Promise(function(resolve) {
    climate.on('ready', function () {
        resolve();
    });
});

var wifiReady = new Promise(function(resolve, reject) {
    function check(){
        if (wifi.isConnected()) {
            if (checkInt) {
                clearInterval(checkInt);
            }
            resolve();
        }
    }
    var checkInt = setInterval(check, 1000);
});

climate.on('error', function(err) {
  console.log('error connecting module', err);
});

Promise.all([climateReady, wifiReady]).then(function(){
    led.output(1);
    checkClimate();
}, function(){
    onError();
});

function onError(){
    var state = 0;
    setInterval(function(){
        if (state) {
            state = 0;
        } else {
            state = 1;
        }
        led.output(state);
    }, 500);
}

function send(temp, hum){
    var options = {
        hostname: '192.168.1.200',
        port: 3035,
        path: '/log?',
        method: 'GET'
    };
    options.path += 'temp=' + temp;
    options.path += '&hum=' + hum;
    console.log('send req...');
    var tesreq = http.request(options, function(res){
        led2.output(0);
    });
    tesreq.on('error', function(err){
        led2.output(0);
    });
    tesreq.end();
}

I got this test to work by adding the following to the http.request callback function:

var tesreq = http.request(options, function(res){
  res.on('data', function (data) {
//    console.log(data)
  })
  res.on('end', function () {
//    console.log('request done');
  })
})

An incompatibility we previously had was not requiring these events to flush, but you might need to add these listeners now. I'll look into this a bit more.

If there are any error messages you are running into, feel free to paste them in a comment here.
