How to use
==========

Installation
------------

:code:`pip install raspyrfm-client`

Usage
-----

For a basic example have a look at the `example.py <https://github.com/markusressel/raspyrfm-client/blob/master/example_simple.py>`_ file.

If you need more info have a look at the `documentation <http://raspyrfm-client.readthedocs.io/>`_ which should help.

Basic Example
-------------
Import required modules
^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: python

from raspyrfm_client import RaspyRFMClient
from raspyrfm_client.device_implementations.controlunit.actions import Action
from raspyrfm_client.device_implementations.controlunit.controlunit_constants import ControlUnitModel
from raspyrfm_client.device_implementations.gateway.manufacturer.gateway_constants import GatewayModel
from raspyrfm_client.device_implementations.manufacturer_constants import Manufacturer


Create the :code:`RaspyRFMClient` object
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Get a client instance by calling:


.. code-block:: python

rfm_client = RaspyRFMClient()

Create a :code:`Gateway` instance
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You can let the library search automatically for gateways available in LAN using:

.. code-block:: python

gateways = rfm_client.search()

This will return a list of Gateways that can later be used to send signals to.

To get a quick overview of what gateway **manufacturers** and **models** are supported call:

.. code-block:: python

rfm_client.list_supported_gateways()

Create a gateway instance with the specified :code:`IP` and :code:`Port` of your Gateway by using:

.. code-block:: python

gateway = rfm_client.get_gateway(Manufacturer.SEEGEL_SYSTEME, GatewayModel.RASPYRFM, "192.168.2.10", 9876)

or

.. code-block:: python

gateway = rfm_client.get_gateway(Manufacturer.SEEGEL_SYSTEME, GatewayModel.RASPYRFM, "192.168.2.10") # defaults to 49880 or the gateway implementations default

Get a :code:`ControlUnit`
^^^^^^^^^^^^^^^^^^^^^^^^^
ControlUnits are the devices that receive the RC signals sent using the gateway, f.ex. a power outlet.

To get a quick overview of what ControlUnits **manufacturers** and **models** are supported call:

.. code-block:: python

rfm_client.list_supported_controlunits()

which will give you an indented list of supported manufacturers and their supported models similar to this:

.. code-block:: text

Elro
RC3500-A IP44 DE
AB440S
AB440D 200W
AB440D 300W
AB440ID
AB440IS
AB440L
AB440SC
AB440WD
BAT
RC AAA1000-A IP44 Outdoor
Brennenstuhl
RCS 1000 N Comfort
RCS 1044 N Comfort
Intertek
Model 1919361
[...]

To generate codes for a device **you first have to get an instance of its implementation** like this:

.. code-block:: python

brennenstuhl_rcs1000 = rfm_client.get_controlunit(manufacturer_constants.BRENNENSTUHL,
manufacturer_constants.RCS_1000_N_COMFORT)

The parameters of the :code:`get_controlunit()` method always need to be an enum value of the specified type.
You can get an enum constant by its name though using:

.. code-block:: python

manufacturer = Manufacturer("Intertechno")
model = ControlUnitModel("IT-1500")

:code:`ControlUnit` channel configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Before you can generate codes with your shiny new gateway and :code:`ControlUnit` implementations you have to specify a channel configuration for your :code:`ControlUnit`. These **configurations can be very different for every device**. The best way to know the correct way of specifying the channel configuration for a specific device is to look at the source code (yes I know...) or by trial and error (even worse). A good :code:`ControlUnit` implementation should tell you how the configuration should look like when specifying it in a wrong way.

However all configurations are a **keyed dictionary**.
So in general there are two ways of passing the channel configuration argument.
One (inline):

.. code-block:: python

device.set_channel_config(value1=1, value2=2)

Two (as a dictionary):

.. code-block:: python

device.set_channel_config(**{
'value1': 1,
'value2': 2
})

**Note** that the **keys always need to be a** :code:`string`.
The second one is the recommended one as it will often result in a much more readable source code.

For our Brennenstuhl device it would look like this:

.. code-block:: python

brennenstuhl_rcs1000.set_channel_config(**{
'1': True,
'2': True,
'3': True,
'4': True,
'5': True,
'CH': 'A'
})

Generate action codes
^^^^^^^^^^^^^^^^^^^^^
Now that you have a properly set up :code:`ControlUnit` you can generate codes for it's supported actions by using an :code:`Action` enum constant that you imported previously.

To get a list of supported actions for a :code:`ControlUnit`call:

.. code-block:: python

brennenstuhl_rcs1000.get_supported_actions()

and generate a code for one of them using your :code:`Gateway` instance:

.. code-block:: python

code = gateway.generate_code(brennenstuhl_rcs1000, Action.ON)

Send the code to the :code:`RaspyRFM` module
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To send a code for your device of choice you can combine the objects in this call:

.. code-block:: python

rfm_client.send(gateway, brennenstuhl_rcs1000, Action.ON)

This will generate a code specific to the passed in gateway implementation and send it to it's host address immediately after.

Custom implementations
======================

The :code:`raspyrfm-client` library is designed so you can implement custom devices in a (hopefully) very easy way.

File Structure
--------------
All :code:`ControlUnit` implementations are located in the :code:`/device_implementations/controlunit/manufacturer/` module and implement the base class :code:`Device` that can be found in :code:`/device_implementations/controlunit/base.py`.

Create a new :code:`ControlUnit`
--------------------------------
To create a new :code:`ControlUnit` implementation for a new manufacturer and model create a new subdirectory for your manufacturer and a python file for your model:

.. code-block::

───raspyrfm_client
│ │ client.py
│ │
│ └───device
│ │ actions.py
│ │ base.py
│ │
│ └───manufacturer
│ │ manufacturer_constants.py
│ │
│ ├───intertek
│ │ Model1919361.py
│ │
│ ├───rev
│ │ Ritter.py
│ │ Telecontrol.py
│ │
│ ├───universal
│ │ HX2262Compatible.py
│ │
│ └───yourmanufacturer
│ yourmodel.py
──────────────────────────────────────────

Implement a :code:`ControlUnit`
-------------------------------

Now the basic implementation of your :code:`ControlUnit` should looks like this:

.. code-block:: python

from raspyrfm_client.device_implementations.controlunit.actions import Action
from raspyrfm_client.device_implementations.controlunit.base import ControlUnit


class YourModel(ControlUnit):
def __init__(self):
from raspyrfm_client.device_implementations.manufacturer_constants import Manufacturer
from raspyrfm_client.device_implementations.controlunit.controlunit_constants import ControlUnitModel
super().__init__(Manufacturer.YourManufacturer, ControlUnitModel.YourModel)

def get_channel_config_args(self):
return {}

def get_pulse_data(self, action: Action):
return [[0, 0], [0, 0]], 0, 0

def get_supported_actions(self) -> [str]:
return [Action.ON]


Most importantly you have to call the :code:`super().__init__` method like shown. This will ensure that your implementation is found by the :code:`RaspyRFMClient` and you can get an instance of your device using :code:`rfm_client.get_controlunit()` as shown before.

If your manufacturer does not exist yet **create a new enum constant** in the :code:`manufacturer_constants.py` file and use its value in your :code:`__init__`.
**Do the same thing for your model name** in the :code:`controlunit_constants.py` file.

You also have to implement all abstract methods from the :code:`Device` class. Have a look at it's documentation to get a sense of what those methods are all about.

After you have implemented all methods you are good to go!
Just call :code:`rfm_client.reload_implementation_classes()` and :code:`rfm_client.list_supported_controlunits()` to check if your implementation is listed.
If everything looks good you can use your implementation like any other one.



Exclude a WIP implementation
----------------------------
To prevent the RaspyRFM client from importing your half baked or base class implementation just include a class field like this:

.. code-block:: python

class YourModel(ControlUnit):
DISABLED = True

[...]
