How to include Fakegato to a platform (FakeGatoHistoryService is not defined)

[ceraz68]

I have a working platform with 8 temperature sensors and struggling to integrate fakegato-history. I added fakegato-history 0.5.6 as a dependency for my plugin and its visible in the node_modules folder. I followed the instructions by adding to module export, in the module for each accessory creation, and returned the service (fakegato related entire are in Bold font).

By I can't resolve an error and pretty new to coding. I'm probably creating the FakeGatoHistoryService in the wrong place or out of scope. Thanks a lot for any hints!

• Here are the relevant extracts of the key code:

module.exports = function(homebridge) {
Service = homebridge.hap.Service;
Characteristic = homebridge.hap.Characteristic;
var FakeGatoHistoryService = require('fakegato-history')(homebridge);
homebridge.registerAccessory("homebridge-heater-reporting", "heater-reporting", HeaterReportingAccessory);
homebridge.registerPlatform("homebridge-heater-reporting", "heater-reporting", HeaterReportingPlatform);
}
function HeaterReportingPlatform(log, config){
this.sensors = config['sensors']; //sensors is an array in config.json, each sensor identified my name, keyword, serial
//(...)my code
}
HeaterReportingPlatform.prototype = {
accessories: function(callback) {
var sensorAccessories = []; //this is an array to store the sensor temperature accessories
for(var i = 0; i < this.sensors.length; i++){
var sensor = new HeaterReportingAccessory(this.log, this.sensors[i]);
sensorAccessories.push(sensor);
}
var saCount = sensorAccessories.length;
callback(sensorAccessories);
}
function HeaterReportingAccessory(log, sensorConfig) {
this.log = log;
this.keyword = sensorConfig["keyword"];
this.name = sensorConfig["name"];
this.sn = sensorConfig["serial"];
}
HeaterReportingAccessory.prototype = {
getServices: function() {
var informationService = new Service.AccessoryInformation();

    informationService
      .setCharacteristic(Characteristic.Name, this.name)
      .setCharacteristic(Characteristic.Manufacturer, "Dallas")
      .setCharacteristic(Characteristic.Model, this.keyword)
      .setCharacteristic(Characteristic.SerialNumber, this.sn);

    var temperatureService = new Service.TemperatureSensor(this.name);
    temperatureService.getCharacteristic(Characteristic.CurrentTemperature)
                            .on("get", this.getTemperature.bind(this));

//line 211
var loggingService = new FakeGatoHistoryService("weather", {displayName: this.name, log: this.log}, {storage: 'fs'});

    **return [informationService, temperatureService, loggingService];**
},

Solved by creating the variable outside of modules exports:

var fakegatoHistory = require( 'fakegato-history' );
module.exports = function(homebridge) {
HistoryService = fakegatoHistory( homebridge );
...}
