Module usage

The project is separated in two layers:

1. ApiConnector

This is the low level connector using the vaillant API and returning raw data directly coming from the API (basically, json formatted responses). The connector is handling the login and session (cookie based). There are 2 helper packages for urls and payload: pymultimatic.api.urls and pymultimatic.api.payloads.

Here is an example on how to use it:

import aiohttp
from pymultimatic.api import Connector, urls, payloads

async with aiohttp.ClientSession() as session:
    connector = Connector('user', 'pass', session)
    # get information about your system
    response = await connector.request('get', urls.system(serial='123'))
    #set the target low heating temperature of a zone to 15 °C
    response = await connector.request('put', urls.zone_heating_setback_temperature(id='1', serial='123'), payload=payloads.zone_temperature_setback(15))

Here is an example of response:

{
    "body": {
        "facilitiesList": [
            {
                "serialNumber": "1234567891234567891234567890",
                "name": "Name",
                "responsibleCountryCode": "BE",
                "supportedBrand": "GREEN_BRAND_COMPATIBLE",
                "capabilities": [
                    "ROOM_BY_ROOM",
                    "SYSTEMCONTROL_MULTIMATIC"
                ],
                "networkInformation": {
                    "macAddressEthernet": "12:34:56:78:9A:BC",
                    "macAddressWifiAccessPoint": "34:56:78:9A:BC:DE",
                    "macAddressWifiClient": "56:78:9A:BC:DE:F0"
                },
                "firmwareVersion": "1.1.1"
            }
        ]
    },
    "meta": {}
}

I would recommend using this layer if you only want to retrieve basic data (outdoor temperature, current temperature of zone, etc.)

2. SystemManager

This layer allows you to interact in a more friendly way with the system and it computes some data for you. The underlying Connector is hidden and raw responses are mapped to more useful objects.

Here is a script example:

#!/usr/bin/env python3

import asyncio
import sys

import aiohttp

from pymultimatic.systemmanager import SystemManager
from pymultimatic.model import System


async def main(user, passw):
    print('Trying to connect with user ' + user)

    async with aiohttp.ClientSession() as session:
        manager = SystemManager(user, passw, session)
        system =  await manager.get_system()
        print(system)


if __name__ == "__main__":
    if not len(sys.argv) == 3:
        print('Usage: python3 dump.py user pass')
        sys.exit(0)
    user = sys.argv[1]
    passw = sys.argv[2]

    asyncio.get_event_loop().run_until_complete(main(user, passw))

Then you can run the script: python3 script.py user passw

The main object to manipulate is pymultimatic.model.System, which is grouping all the information about your system.

In case of error coming from the API, a pymultimtic.api.Error is raised, containing the response and the payload sent to the API.

I would recommend using this layer if you want to do more complex things, e.g: if you want to get the target temperature for a room or a zone, it can become a bit complex since you have to deal with holiday mode, quick mode, quick veto, time program, etc. This layer is hiding you this complexity.
