SAPUI5 Cordova Electricity Meter Reading

[former_member193140]

In many homes there are still electricity meters with a mechanical counter that do not provide a direct interface for reading the consumption of electrical energy. In this blog, I am trying to capture the consumption of electrical energy with a mobile device (Android) as a scanner to read the information from the mechanical counter and record it in the database like SAP HCP. In this case, we are going to build a SAPUI5 Cordova electricity meter reading with the SDK from Anyline.io.

• Go to Anyline.io website to download the SDK Cordova plugin and obtain the license. 
• Setup and build the Cordova project under C:\programs
  • cordova create C:\programs\meterReading com.enterprisemobility.meterReading meterReading
  • cd c:\programs\meterReading\
    
  • cordova platform add android
  • cordova plugin add <path_to_AnylineSDK_Cordova_Plugin>
    

• Create a function to scan the mechanical counter by calling the scanElectricMeter function in ElectricScan.controller.js:
  

  
  
  scanElectricMeter: function() {
  
  cordova.exec(this.onResult, this.onError, "AnylineSDK", "scanElectricMeter", this.energyConfig);
  
  }
  
  
  
  
  
  
  
  
  
  
  
  
  
  

• If scan is success, it will call the onResult function which will capture the meter reading value and pass the information to the ScanResult.view.js.
  

  
  
  onResult: function(result) {
  
  var meterType = []; var reading=[];
  
  meterType.push(result.meterType);
  
  reading.push(result.reading);
  
  var data = [];
  
  for(var i = 0; i < meterType.length; i++) {
  
  data.push({"meterType": meterType[i], "reading": reading[i]});
  
  }
  
  var oModel1 = new sap.ui.model.json.JSONModel({ "zgwmat": data });
  
  sap.ui.getCore().setModel(oModel1, "zgwmatmodel");
  
  var bus = sap.ui.getCore().getEventBus();
  
  bus.publish("nav", "to", {
  
    id : "scanresult",
  
  });
  
  },
  
  
  
  
  
  
  
  
  
  
  
  
  
  

• I have attached the complete source code in this blog: www.zip. Replace the c:\Programs\meterReading\www folder with the attached www folder.
  
• Download SAPUI5 runtime here and save it under C:\Programs\meterReading\www\resources
• Build the cordova project under c:\programs\meterReading, execute command cordova build
• Install the generated .apk from c:\Programs\meterReading\platforms\android\build\outputs\apk to your Android device.

That's it!
