SmartMesh IP mesh networks and and IBM Watson IoT are perfectly complementary. Sending data gathered by a SmartMesh IP mote into the Watson IoT platform is a breeze, as you will see in this recipe.
Overview
Create your network
We assume you have a DC9000B SmartMesh IP starter kit
Plug the manager into your computer's USB board and its blue LED switches on
Switch on at least one mote, two green LEDs are steady-on when the mote has successfully joined the network and is publishing data:
What just happened?
That's it, you have a fully functional SmartMesh IP network with every mote publishing a temperature reading every 30s.
Run the software
On your computer, you will need to run two programs: JsonServer and Node-RED
JsonServer
JsonServer is a program developed by the DustCloud community and part of the SmartMesh SDK.
It connects to your SmartMesh IP manager and opens an HTTP JSON interface that Node-RED can connect to.
Download the latest release of the SmartMesh SDK at https://github.com/dustcloud/smartmeshsdk/releases
Run the application
Node-RED
Publish to Watson IoT Quickstart
Copy the following Node-RED flow into Node-RED:
JSON version of the flow
https://gist.github.com/twatteynelinear/9626af15ec56cf661ffe70734d3b11e0/raw/
Double-click on "connect serial port" and change "COM13" by the name of the serial port you noted above
Click the Deploy button on Node-RED
Click on the left of the "connect serial port" widget
Make sure the debug tab on the right contains "200"
Click on the left of the "get status" widget
Make sure the debug tab on the right contains "connected"
Choose any one of your motes, and read its label, in my case "3FFEE6"
In Node-RED, double-click on the function widget
Replace "3FFEE6" by what you have on your label and click Done
Double-click on the event widget
Change the Quickstart Id by your mote's identifier, and click Done
Click Deploy
Go to https://quickstart.internetofthings.ibmcloud.com
check the box to accept the terms and conditions
enter the identifier of your mote and press Go
You start by seeing an empty screen, this is normal as the mote only publishes every 30s
Every 30s, a new datapoint plots live
