> SparkCore\_Node-RED - Spark Core and Node-RED integration

Spark Core and Node-RED are great IOT tools. If these two can work together then it is more awesome. So I decided to create a simple Node-RED node for Spark Core. The node implements basic things to interact with Spark Core, such as call a function, read a variable and subscribe to events. This node defines INPUT and OUTPUT nodes. Input node can be used to call a function, read a variable and subscribe to events. The output node can be used to call a function and pass an input parameter. Following are the return values:

**Function call**

1. **msg.raw** contains the raw JSON string returned
2. **msg.payload** contains the return value of the function
3. **msg.id** contains the core id
4. **msg.name** contains the core name

**Read a Variable**

1. **msg.raw** contains the raw JSON string returned
2. **msg.payload** contains the value of the variable
3. **msg.name** contains the name of the core

**Subscribe to variables**

1. **msg.raw** contains the raw JSON string returned
2. **msg.payload** the event data
3. **msg.ttl** contains he TTL
4. **msg.published\_at** contain the published date and time
5. **msg.coreid** contains the core id

**Sample Applications**

I have created two samples created. The first sample demonstrates the subscribe to events functionality and uses DHT Temperature and Humidity sensor to log data to **Xively**. This Spark Core application published temperature and humidity at particular intervals and the Node-RED application send this data to **Xively**. This uses INPUT node.

The second sample uses MQTT to set color of RGB led. This uses OUTPUT node and Eclipse Sandbox MQTT server ([iot.eclipse.org:1883](http://iot.eclipse.org:1883)). The Node-REd application listens for MQTT messages and forward to Spark Core which parses the color (in the format R,G,B) and set the LED color.

Hi. Is there an npm that I can install so that this shows up in my Node-RED interface?

@sriram155, while doing this the node-red nodes were not npm capable, as of Node-RED 0.9.1 nodes can be installed using npm. I am preparing the npm and will publish it this weekend or so and update here.

@alkopop79,

1. Go to `<Node-RED>\nodes\hardware` folder.
2. Create a folder named spark.
3. Copy two files from [https://github.com/krvarma/SparkCore\_Node-RED/tree/master/spark-node](https://github.com/krvarma/SparkCore_Node-RED/tree/master/spark-node).

You can use **`node red.js -v`** to debug any issues.

Let me know any issue facing.

@krvarma when i followed the above instruction, i get the following error

@sriram155, the error shows some HTML tags which the `sparkcore.js` have, can you paste your `sparkcore.js` here?

@sriram155, can you execute following command an check:

npm install request  
npm install eventsource

@krvarma it’s still the same even after installing the request and eventsource packages.

@sriram155, I tried the same with my RPi and Windows machine, its working fine. Is there any detailed error message, I mean from `node red.js -v`?

@sriram155, can you take the latest and check it is working or not, I just made some changes based on an assumption, lets see it is working or not.

Here is the version 0.0.7 NPM install package. Following command will install the package. The node-red authentication mechanism is implemented in this version. The authentication data, core id and access token are stored in separate file, so when you copy and paste the flow the auth data is not copied.

```
npm install node-red-contrib-sparkcore

```

I want to thank [Dave Conway-Jones](https://github.com/dceejay) for his valuable inputs.

@krvarma Thanks a lot. Does this work with Spark local cloud?

@sriram155 , this version 0.0.7 does not support the local cloud, but the next version will support this. I am working on it and may be early next week I can update it.

As I mentioned in the previous post this version has Authentication, Spark Core icon and some message modification to make it more consistent for all function call, read variable and the publish/subscribe.

@krvarma thanks for the note. I’m working on the local cloud. I’ll bookmark this thread for future updates.

@sriram155, I just published the version 0.0.8, can you check you are able to connect to local cloud?
