Sensor Tag 2 Smart Light

1) Use the latest version of "Jessie" on the Raspberry Pi 2 -https://www.raspberrypi.org/downloads/raspbian/

2) Connect the Raspberry Pi 2 to the internet and "Putty" into it from another computer. 

3) Connect the Blinkstick to the Raspberry Pi 2 - 

https://www.blinkstick.com/help/raspberry-pi-integration

4) Verify the Blinkstick is working (it will turn a random color). Type the following into the Raspberry Pi 2 terminal:

sudo blinkstick random

To avoid permission errors type this into terminal:

sudo blinkstick --add-udev-rule

Now "sudo" will not be needed when entering Blinkstick commands. Verify this by entering the command below. The Blinkstick should turn a random color. 

 blinkstick random 

4) Follow the instructions to run Node Red and also install NPM on your Raspberry Pi 2 - 

http://nodered.org/docs/hardware/raspberrypi.html

5) Once the Blinkstick and Node Red are set up on the Raspberry Pi 2, navigate to the Node Red directory to install some nodes.

cd ~/.node-red

6) Install "dweetio" and "blinkstick" nodes into Node Red.

sudo npm install node-red-node-blinkstick

sudo npm install node-red-node-dweetio

7) Restart Node Red and the nodes will be installed.  

8) Download the Sensor Tag app for either iOS or Android - 

http://www.ti.com/ww/en/wireless_connectivity/sensortag2015/appsAndPartners.html

9) Run the Sensor Tag app and edit the cloud configuration to send the data to Dweet.IO.

10) Name the "Thing" in Dweet.io settings on the Sensor Tag app. *Remember this unique name because you'll need it for your Node Red Flow later.

12) Open Node Red in your browser using the IP address of your Pi followed by :1880. 

Ex. 192.168.2.67.1880

13) Copy the flow below into your Node Red. (Import > Clipboard > Paste). Once you see the flow pasted into Node Red, change the Dweetio Node to the name you set up in the phone app for your Ti Sensor Tag 2.

15) Check the debug tab on your Node Red (located on the far right). The Sensor Tag 2 data will look like this:

{ "ambientTemp": 26.03, "objectTemp": 20.62, "humidity": 85.51598, "pressure": 1018.3, "altitude": -0.7708694, "accelX": -0.06, "accelY": 0.04, "accelZ": 1.03, "gyroX": -0.59, "gyroY": 0.81, "gyroZ": -0.76, "magX": 83.8, "magY": 80.2, "magZ": 116.47, "light": 18.5 } 

16) Set the "blinkstick" node to either blink, morph, pulse depending on what you like. I prefer morph. 

 16) Now you have a smart light that responds to remote lighting conditions. The Raspberry Pi does not need to be on the same network as the cell phone that is publishing the Sensor Tag 2 data. Which makes it extra cool.
