IoT Power Consumption

Description

The purpose of this project is reading power consumption from refrigerators. This project uses an IoT Edge package to stream data from power sensors into an IoT Edge pipeline, process it and forward it to IoT Hub

Creating a BLE Module

Followed this Tutorial to create a Node.js BLE module to generate fridge readings from the UMass Trace Repository and to stream them to the IoT Edge.

Datastructure

The data used in the csv files follows the following format:

Timestamp	Refrigerator Power Usage (kW)
1/1/2016 0:00	0.132692222

Deployment Steps

Creating The IoTHub

1. Deploy ARM Template
2. Once deployed, open the newly created IoT Hub, go to Device Explorer, click Add and enter a deviceId (the name of each device in Gateway Config).
3. Repeat for all devices.
4. After all are created, go to each one and copy the primary key into the Gateway Config, replacing all the values resembling <<DeviceKey1>>.
5. Replace the value for IoTHubName with the name you chose for your IoT Hub.

Creating the Function Handler

1. Open your new function app.
2. Create a new function for EventHubTrigger - Javascript called IoTHubHandler
3. Click new next to Event Hub connection
4. Click IoT hub, select your IoT hub name and the events endpoint and click select.
5. Enter your IoT hub name in the Event Hub name field and click create.

Deploy IoT Edge to a FunctionApp

1. Open your new function app.
2. Create a new function called IoTEdge
3. Upload the folders: data, devices and files: function.json, gw.config.json, index.js and package.json.
4. Navigate to the project Kudu console
5. Run:

   cd site\wwwroot\IoTEdge
   npm install

6. Using the function url, start the function.

Development Environment

Install the dependencies

npm install

Run the IoTEdge

npm start
