Google Apps Script that records temperature values from TMP36 sensor connected to Particle Photon, Nest thermostat and WeatherUnderground API into Sheet. More @ http://techiys.com/tagged/WiFiTemp.
//PARTICLE DEVICE
//Define the Particle Photon's Device ID and Access Token. Then use those variables to create the URL to access JSON output from board.
var deviceID = "3e002..................."; //Set to specific device ID.
var accessToken = "6dae...................................."; //Set to specific device's access token.
var particleUrl = 'https://api.particle.io/v1/devices/' + deviceID + '/analogvalue?access_token=' + accessToken;
//WEATHERUNDERGROUND
//Define WeatherUnderground API key, weather station location and request type. Then create URL to access JSON results.
var apiKey = "d1792..........."; //Set to your API Key.
var requestType = "conditions";
var wStation = "KILCHICA310"; //Set to desired weather station location.
var weatherUrl = 'http://api.wunderground.com/api/' + apiKey + '/' + requestType + '/q/pws:' + wStation + '.json';
//NEST THERMOSTAT
//Define Nest URL, device ID and OAuth v2.0 credentials
var nestID = "N4ndF..........................."
var nestAuth = "c.PNi.............................................................................................................................................";
var nestUrl = "https://developer-api.nest.com";

//Parse JSON output from particleURL into array set photonValue to Voltage reading from Photon JSON output convert to C then F and write in results array.
