* Documentation: https://htheatpump.readthedocs.io
* Free software: `GNU General Public License v3 <https://www.gnu.org/licenses/gpl-3.0.en.html>`_


Introduction
------------

This library provides a pure Python interface to access `Heliotherm <http://www.heliotherm.com/>`_ heat pumps
over a serial connection. It's compatible with Python version 3.4, 3.5 and 3.6.

Features
~~~~~~~~

* read the manufacturer's serial number of the heat pump
* read the software version of the heat pump
* read and write the current date and time of the heat pump
* read the fault list of the heat pump
* query whether the heat pump is malfunctioning
* query for several parameters of the heat pump
* change parameter values of the heat pump
* fast query of MP data points / parameters ("Web-Online")


Todo
~~~~

* check access right for writing parameters of the heat pump
* read and write the time programs of the heat pump
* add some (more) examples
* add some (more) unit tests
* cleanup/extend documentation

Installing
----------

You can install or upgrade :mod:`htheatpump` with:

.. code-block:: console

$ pip install htheatpump --upgrade

Or you can install from source with:

.. code-block:: console

$ git clone https://github.com/dstrigl/htheatpump.git
$ cd htheatpump
$ python setup.py install


Getting started
---------------

To use :mod:`htheatpump` in a project take a look on the following example. After establishing a connection
with the Heliotherm heat pump one can interact with it by different functions like reading or writing
parameters.

.. code:: python

from htheatpump.htheatpump import HtHeatpump

hp = HtHeatpump("/dev/ttyUSB0", baudrate=9600)
try:
hp.open_connection()
hp.login()
# query for the outdoor temperature
temp = hp.get_param("Temp. Aussen")
print(temp)
# ...
finally:
hp.logout() # try to logout for an ordinary cancellation (if possible)
hp.close_connection()

A full list of supported functions can be found in the :mod:`htheatpump` documentation at
`readthedocs.io <https://htheatpump.readthedocs.io/en/latest/?badge=latest>`_.


Logging
~~~~~~~

This library uses the :mod:`logging` module. To set up logging to standard output, put

.. code:: python

import logging
logging.basicConfig(level=logging.DEBUG)

at the beginning of your script.

----------

History
=======

1.1.0 (2019-02-23)
------------------

* added some more heat pump parameters (data points) in :file:`htparams.csv`
* extended sample script :file:`htfaultlist.py` by the possibility to write a JSON/CSV file
* added new sample scripts :file:`hthttp.py` and :file:`htfastquery.py`
* fixed some formatting (flake8) errors
* some improvement for the reconnect in the :meth:`~HtHeatpump.login()` method of class :class:`HtHeatpump`
* changed return type of :meth:`HtHeatpump.get_fault_list()` from :obj:`dict` to :obj:`list`
* added support for Python 3.6
* added support for a user specific parameter definition file under :file:`~/.htheatpump/htparams.csv`
* extended sample :file:`htbackup.py` to store also the limits (MIN and MAX) of each data point
* added method to verify the parameter definitions in :file:`htparams.csv` during a :meth:`HtHeatpump.get_param()`,
:meth:`HtHeatpump.set_param()` or :meth:`HtHeatpump.query()`; this is just for safety to be sure that the
parameter definitions in :class:`HtParams` are correct (deactivated by default, but can be activated by setting
the property :attr:`HtHeatpump.verify_param` to :const:`True`)
* added new method :meth:`HtHeatpump.fast_query()` to retrieve "MP" data point values in a faster way ("Web-Online")
* extended the :meth:`HtHeatpump.login()` method to perform an update of the parameter limits if desired

1.0.0 (2018-01-12)
------------------

* First release on PyPI.
