NPM Software modules used:

• node-static - simple web server to demonstrate project
• os - used to get the server IP address and return it to a client
• tessel - cannot live without it ;)
• twilio - used with a free account to send an SMS message
• relay-mono - try turning on a rotating light/etc.
• tessel-toggle-power - toggles a relay module, or specified pin (wire up your own relay and trigger it)

Instructions

1. Get a free account from Twilio, then activate a From number
2. Edit app.js: enter your accound SID, token, twilio (from) number, cell number and WEB_ADDRESS
3. Run node server which you can then view @ localhost:3000
4. t2 list to make sure your Tessel is connected, then run t2 run app.js
5. Your T2 app will noisily output console logs (notice DEBUG = true)
6. Switch to your node server and press CTRL+C to stop the web server
7. When the T2 app runs http.get and it fails, you will get an SMS message
8. Feeling adventurous? Have a Relay module or breadboard, some jumper cables and lights? Enable the relay-mono and tessel-toggle-power lines within app.js. If you use a Relay module, plug it into port A as shown in the code. If you use a pin simply edit the code with the pin-number that you prefer.

So now the question is, what else can you do with this?! :)
