Do you want to connect your device directly to cloud services or to Watson IoT? If the latter one is the thing you wanna wish to do you will need a Bluemix Account, Raspbian Jessie account, a Raspberry Pi Model B/ Model B+/ 2, and minimim 8GB SD card. After you make sure that you have all the necessary stuff you can use:
sudo apt-get update
sudo apt-get install nodered
And then to start the Node-red:
node-red-start
There are a lot of useful material on the internet, you can follow the instructions and do whatever you want with it. I'm using my Raspberry Pi
to control my home security system of my property in Spain and I must admit that it's very useful.
