# coffeefy

## Description

Coffeefy let you control a coffee maker via the Internet using a RESTful API provided by an express.js-server. However, this system isn't reliable yet and should run under supervision.

## System architecture

![Systemarchitektur](https://cdn.rawgit.com/rehne/coffeefy/b97ae538/docs/Architekturdiagram%20IoT%203.0.svg)

## Used hardware

- Raspberry Pi 3

- Senseo 7810 Coffee Machine

- HC-SR04 Ultrasonic Sensor

- 3 Relays

- 2 Resistors(680Ohm/1kOhm)

- minor small parts (optional breadboard, wires etc.)

## Installation

- clone repository

- navigate to ./node

- run `npm install` to install the dependencies

- To start the webserver, run: `nodemon app` or `node ./bin/www`

- open `http://localhost:3000` in your browser

You can run Coffeefy as a daemon service using "forever". (see below)

After Installation you can start the node.js server by running `forever start ./bin/www`.

To see what's going on, determine the logfile path by running `forever list` and run

`tail -f `

(Instructions for running `ultrasonic.py` in background)

## Required Python libraries

- RPi.GPIO via `sudo apt-get install rpi.gpio`

- paho-mqtt via `pip install paho-mqtt`

## Useful node.js modules and other ressources

- [mqtt.js](https://github.com/mqttjs/MQTT.js)

- [python-shell](https://github.com/extrabacon/python-shell)

- [Correct usage of GPIO.cleanup()](http://raspi.tv/2013/rpi-gpio-basics-3-how-to-exit-gpio-programs-cleanly-avoid-warnings-and-protect-your-pi)

- Running a node js server.. [forever(Github-Repo)](https://github.com/foreverjs/forever)

- [nodemon](http://nodemon.io/) monitors for any changes in source, restarts the server automatically if necessary.

## Troubleshooting

- Installing paho-mqtt causes an error. Missing "Python.h"? → Install the python developer package via `apt-get install python2.7-dev`.

- `node app.js` results in a crash. → I dunno Y,  just install `nodemon` via npm. →  `node ./bin/www`
