Pelops Overview
``Epidaurus`` 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 epidaurus
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/epidaurus.git
cd epidaurus
sudo python3 setup.py install
This will install the following shell scripts: \* ``epidaurus``
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 [2]_ 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 \* controller - 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_epidaurus.log
controller:
value-idle: 4.5 # idle mode output - heating system does nothing
value-min: 5 # minimum output for active (=heating) system
value-max: 23 # maximum value for heater
pid-max-output: 500 # for normalization purposes. this is the expected maximum output of the pid controller
idle-mode-threshold: 0.75 # if temperature is this value above set-point, set output to volt-idle value.
topics-sub:
set-point: /test/thermostat/set-point # receive new set point via this topic
input: /test/thermostat/input # receive input (=temperature) updates via this topic
topics-pub:
output: /test/thermostat/output # publish resulting output voltage to this topic
pid:
p-gain: 75
i-gain: 20
d-gain: 0
update-interval: 30 # in seconds (in fact not used anywhere)
windup-guard: 20 # protect integral term from windup
systemd
-------
- add systemd example.
For Developers
==============
Getting Started
---------------
The project consists of two main modules: \* ``pid`` - classic
pid-implementation \* ``controller`` - wraps around the ``pid`` and adds
thermostat related behavior like minimum output, idle output,
normalization of pid output to expected voltage range.
The values for ``pid`` and some for ``controller`` must be determined
using experiments with the real system. To get a first set of parameters
you can use ``tests/test_controller_model_nomqtt.py`` together with
``tools/model_trivial_flat.py``.
Todos
-----
- Auto parameterization of pid
- ...
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/epidaurus/merge_requests>`__
/ `bug reports <https://gitlab.com/pelops/epidaurus/issues>`__ are
always welcome.

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).
