Here you will find the guide to install Raspbina

https://www.raspberrypi.org/help/noobs-setup/

Please select Raspbina as operating system.

Clone CraftBeerPI from GitHub

git clone https://github.com/Manuel83/craftbeerpi.git

Run the installation script

sudo ./install.sh

As part of the installation you will ask if you like to start CraftBeerPI after boot automatically. If you have selected this at the first installation just run the installation again and select 'y' when you are ask if CraftBeerPI should start after boot.

sudo python runserver.py

The App is now avaibale under: http://<server_id>:5000 im Browser aufrufbar.

To import the database from "Kleiner Brauhelfer" select "Steps". There you will find a buttton "Import Kleiner Brauhelfer". Upload the kb_daten.sqlite of Kleiner Brauhelfer.

The Kiosk Mode requires that CraftBeerPI is start at boot. Make sure that SSH is still enabled otherwise its not possible remove this kiosk mode.

sudo raspi-config

Change your boot to desktop environment. This will start-up the GUI instead of the CLI and automatically will login to user 'pi'.

Install Chromium Browser

sudo apt-get install chromium

Change startup Config

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

Change the file that it looks like this

@lxpanel --profile LXDE
@pcmanfm --desktop --profile LXDE
@xset s off
@xset -dpms
@xset s noblank
@sed -i 's/"exited_cleanly": false/"exited_cleanly": true/' ~/.config/chromium/Default/Preferences
@chromium --noerrdialogs --kiosk http://localhost:5000 --incognito

Reboot the Raspberry PI

sudo reboot

Out of the box CraftBeerPI is supporting 1-wire thermometers. But integrating a custom thermometer protocol is quite simple.

Just overwrite 3 simple method of the w1_thermometer.py

## This method gets invoked only once during start time.
## This is the right place if the Thermometer needs to be initialize
## during server start.
@brewinit()
def initThermo():
    #Custom Code here
    # no return value

## Define which Thermometers are available
## Return the id/name of available thermometers as string array
def getW1Thermometer():
    ## Custom code here!
    return ["DummySensor1","DummySensor2"]

## This method gets invoked every 5 seconds for each thermometer
## Just read the current value and return it a float
def tempData1Wire(tempSensorId):
    ## Custom code here!
    return 100.00
