Directory Structure

directory	description
bin	the main python file is based here
dev	if you plan to create a plugin then this is the folder you want to have a closer look at
doc	Source files for the user- and developer documentation
etc	the three basic configuration files smarthome.yaml, module.yaml, plugin.yaml, logic.yaml and logging.yaml are located here, you will edit these files to reflect your basic settings
items	put here your own files for your items
lib	some more core python modules are in this directory. You won't need to change anything here
logics	here your logic files are put
modules	here are all loadable core-modules located (one subdirectory for every module)
plugins	here are all plugins located (one subdirectory for every plugin). The plugins have to be installed from a separate repository (smarthomeNG/plugins)
scenes	the scenes are stored here
tests	The code for the automated travis tests is stored here
tools	there are some tools which help you for creating an initial configuration
var	everything that is changed by smarthome is put here, e.g. logfiles, cache, sqlite database etc.

Some more detailed info on the configuration files

As of Version 1.5 the old conf format will still be valid but will be moved out of the docs since it's deprecated now for some time.

etc/smarthome.yaml

Upon installation you will need to create this file and specify your location.

# smarthome.yaml
# look e.g. at http://www.mapcoordinates.net/de
lat: '52.52'
lon: '13.40'
elev: 36
tz: Europe/Berlin

etc/module.yaml

Upon installation you will need to create this file and configure the modules and their parameters. On first start of SmartHomeNG this file is created from etc/module.yaml.default.

An example is shown below:

# module.yaml
http:
    module_name: http
    starturl: admin

admin:
    module_name: admin

#enable, if mqtt protocol is going to be used
#mqtt:
#    module_name: mqtt

etc/plugin.yaml

Upon installation you will need to create this file and configure the plugins and their parameters. On first start of SmartHomeNG this file is created from etc/plugin.yaml.default.

An example is shown below:

# plugin.yaml
database:
    plugin_name: database
    driver: sqlite3
    connect:
    -   database:./var/db/smarthomeng.db
    -   check_same_thread:0

cli:
    plugin_name: cli
    ip: 0.0.0.0
    update: True

websocket:
    plugin_name: visu_websocket


knx:
    plugin_name: knx
    host: 127.0.0.1
    port: 6720

ow:
    plugin_name: onewire

smartvisu:
    plugin_name: visu_smartvisu
    smartvisu_dir: /var/www/html/smartVISU

etc/logic.yaml

In the logic.conf you specify your logics and when they will be run. On first start of SmartHomeNG this file is created from etc/logic.yaml.default.

An example is shown below

# etc/logic.yaml
AtSunset:
    filename: sunset.py
    crontab: sunset

items/

This directory contains one or more item configuration files. The filename does not matter, except it has to end with '.yaml'.

# items/global.yaml
global:
    sun:
        type: bool
        attribute: foo

logics/

This directory contains your logic files. Simple or sophisitcated python scripts. You could address your smarthome item by sh.item.path. If you want to read an item call sh.item.path() or to set an item sh.item.path(Value).

# logics/sunset.py
if sh.global.sun():       # if sh.global.sun() == True:
    sh.gloabl.sun(False)  # set it to False
