Pelops Overview
``Eurydike`` is part of the collection of mqtt based microservices
`pelops <https://gitlab.com/pelops>`__. An overview on the microservice
architecture and examples can be found at
(http://gitlab.com/pelops/pelops).
For Users
=========
Installation Core-Functionality
-------------------------------
Prerequisites for the core functionality are:
::
sudo apt install python3 python3-pip
sudo pip3 install paho-mqtt pyyaml pelops
Install via pip:
::
sudo pip3 install eurydike
To update to the latest version add ``--upgrade`` as prefix to the
``pip3`` line above.
Install via gitlab (might need additional packages):
::
git clone git@gitlab.com:pelops/eurydike.git
cd eurydike
sudo python3 setup.py install
This will install the following shell scripts: \* ``eurydike``
The script cli arguments are: \* '-c'/'--config' - config file
(mandatory) \* '-v' - verbose output (optional) \* '--version' - show
the version number and exit
YAML-Config
-----------
A yaml [1]_ file must contain four root blocks: \* mqtt - mqtt-address,
mqtt-port, and path to credentials file credentials-file (a file
consisting of two entries: mqtt-user, mqtt-password) \* logger - which
log level and which file to be used \* eventdetectors - parameters for
the controller and the embedded pid
::
mqtt:
mqtt-address: localhost
mqtt-port: 1883
credentials-file: ~/credentials.yaml
log-level: INFO
logger:
log-level: DEBUG # DEBUG, INFO, WARNING, ERROR, CRITICAL
log-file: test_eurydike.log
eventdetectors:

# on-violation: event_detected # on detection of a threshold violation send this value to topic-pub

type: onband # detector type identifier
upper-threshold: 8 # upper threshold for on band detection
lower-threshold: 7 # lower threshold for on band detection
topic-sub: /test/value
topic-pub: /test/band
responses: # leave value empty or remove line for no response
on-violation: event_detected # on detection of a threshold violation send this value to topic-pub
on-restoration: event_ended # on the event of returning to valid values send this value to topic-pub
active: True # entry ignored if set to False

For Developers
==============
Getting Started
---------------
The project consists of two main modules:
- ``eventdetectionmanager`` - manages all configured event detectors
- ``abstracteventdetector`` - base class for all event detectors
Todos
-----
- ... ?
Misc
----
The code is written for ``python3`` (and tested with python 3.5 on an
Raspberry Pi Zero with Raspbian Stretch).
`Merge requests <https://gitlab.com/pelops/eurydike/merge_requests>`__ /
`bug reports <https://gitlab.com/pelops/eurydike/issues>`__ are always
welcome.
.. [1]
Currently, pyyaml is yaml 1.1 compliant. In pyyaml On/Off and Yes/No
are automatically converted to True/False. This is an unwanted
behavior and deprecated in yaml 1.2. In copreus this autoconversion
is removed. Thus, On/Off and Yes/No are read from the yaml file as
strings (see module baseclasses.myconfigtools).
