==========



Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven Controller.

Of course, since it is basically just a robot sensing temperature and controlling

environmental agitators (heating/cooling) you can use it as inspiration / basis

when you're in need of a PID based temperature controller for your project.

Don't forget to share and drop a link, when you do :)

## Hardware



  * Raspberry Pi (Rev 2B, Zero W)

  * MAX 31855/6675 Cold-Junction K-Type Thermocouple

  * GPIO driven Solid-State-Relays/MOSFETs



## Installation



### Dependencies



We've tried to keep external dependencies to a minimum to make it easily

deployable on any flavor of open-source operating system. If you deploy it

successfully on any other OS, please update this:



#### Currently tested versions



  * greenlet-0.4.2

  * bottle-0.12.4

  * gevent-1.0

  * gevent-websocket-0.9.3



#### Ubuntu



    $ sudo apt-get install python3-pip python-dev libevent-dev

    $ sudo pip3 install ez-setup

    $ sudo pip3 install greenlet bottle gevent gevent-websocket



#### Raspbian



    $ sudo apt-get install python3-pip python-dev libevent-dev

    $ sudo pip3 install ez-setup

    $ sudo apt-get install python-gevent python-gevent-websocket

    $ sudo pip3 install greenlet bottle



#### Gentoo



    $ emerge -av dev-libs/libevent dev-python/pip

    $ pip install ez-setup

    $ pip install greenlet bottle gevent gevent-websocket



#### Raspberry PI deployment



If you want to deploy the code on a PI for production:



    $ pip3 install RPi.GPIO



This **only applies to non-Raspbian installations**, since Raspbian ships

RPi.GPIO with the default installation.



If you also want to use the in-kernel SPI drivers with a MAX31855 sensor:



    $ sudo pip3 install Adafruit-MAX31855



### Clone repo



    $ git clone https://github.com/apollo-ng/picoReflow.git

    $ cd picoReflow



## Configuration



All parameters are defined in config.py, just copy the example and review/change to your mind's content.



    $ cp config.py.EXAMPLE config.py



## Usage



### Server Startup



    $ python3 picoreflowd.py



### Autostart Server onBoot

If you want the server to autostart on boot, run the following commands



    sudo cp /home/pi/picoReflow/lib/init/reflow /etc/init.d/

    sudo chmod +x /etc/init.d/reflow

    sudo update-rc.d reflow defaults



### Client Access



Open Browser and goto http://127.0.0.1:8081 (for local development) or the IP

of your PI and the port defined in config.py (default 8081).
